10 Below is a list of problems identified during the GDB 5.0 release
11 cycle. People hope to have these problems fixed in 5.1.
15 Update GDB's coding standard documentation. Known topics:
17 o alloca/malloc et.al.
29 Wow, three bug reports for the same problem in one day! We should
30 probably make fixing this a real priority :-).
32 Anyway, thanks for reporting.
34 The following patch will fix the problems with setting breakpoints in
35 dynamically loaded objects:
37 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00230.html
39 This patch isn't checked in yet (ping Michael/JimB), but I hope this
40 will be in the next GDB release.
42 There should really be a test in the testsuite for this problem, since
43 it keeps coming up :-(. Any volunteers?
49 x86 linux GDB and SIGALRM (???)
50 http://sourceware.cygnus.com/ml/gdb/2000-q1/msg00803.html
52 This problem has been fixed, but a regression test still needs to be
53 added to the testsuite:

65 GDB misses watchpoint triggers after proceeding over a breakpoint on
70 GDB 5.0 doesn't work on Linux/SPARC
72 There are two parts to this.
74 o GDB 5.0 doesn't work on GNU/Linux/SPARC32
76 o GDB 5.0 doesn't work on the new target
79 GDB does build on both these targets.
81 The first problem is the one that should be fixed.
85 GDB 5.1 - New features
86 ======================
88 The following new features should be included in 5.1.
92 Enable MI by default. Old code can be deleted after 5.1 is out.
96 o syntax change where a list would
98 [ foo=a, foo=b, foo=c ]

126 Java (Anthony Green, David Taylor)
128 Anthony Green has a number of Java patches that did not make it into
129 the 5.0 release. The first two are in cvs now, but the third needs
130 some fixing up before it can go in.

145 A predicate to this is the multi-arching of SOFTWARE_SINGLE_STEP(). A
146 patch has been submitted.

237 GDB 5.1 - Known Problems
238 ========================
244 The z8k has suffered bit rot and is known to not build. The problem
245 was occuring in the opcodes directory.
251 The m88k has suffered bit rot and is known to not build.
255 Solaris 8 x86 CURSES_H problem
256 http://sources.redhat.com/ml/gdb/2000-07/msg00038.html
258 The original problem was worked around with:
262 * configure.in: Enable autoconf to find curses.h on Solaris 2.8.
263 * configure: Regenerate.
265 When building both GDB and SID using the same source tree the problem
266 will still occure. sid/component/configure.in mis-configures
267 <curses.h> and leaves wrong information in the config cache.
276 Thread support. Right now, as soon as a thread finishes and exits,
277 you're hosed. This problem is reported once a week or so.
281 GDB 5.2 - New features
282 ======================
286 GCC 3.0 ABI support (but hopefully sooner...).
290 Objective C/C++ support (but hopefully sooner...).
297 The following cleanups have been identified as part of GDB 5.2.
301 Remove old code that does not use ui_out functions and all the related
302 "ifdef"s. This also allows the elimination of -DUI_OUT from
303 Makefile.in and configure.in.
309 Eliminate all warnings for at least one host/target for the flags:
310 -Wimplicit -Wreturn-type -Wcomment -Wtrigraphs -Wformat -Wparentheses
311 -Wpointer-arith -Wuninitialized
315 Deprecate, if not delete, the following:
321 Replaced by, on the target side
323 and on core-gdb side:
324 {read,write}_register_gen()
325 Remote.c will need to use something
326 other than REGISTER_BYTE() and
327 REGISTER_RAW_SIZE() when unpacking
330 STORE_PSEUDO_REGISTER
331 FETCH_PSEUDO_REGISTER
332 Now handed by the methods
333 gdbarch_{read,write}_register()
334 which sits between core GDB and
338 REGISTER_CONVERT_TO_RAW
339 REGISTER_CONVERT_TO_VIRTUAL
340 I think these three are redundant.
341 gdbarch_register_{read,write} can
342 do any conversion it likes.
344 REGISTER_VIRTUAL_SIZE
345 MAX_REGISTER_VIRTUAL_SIZE
346 REGISTER_VIRTUAL_TYPE
347 I think these can be replaced by
349 FRAME_REGISTER_TYPE(frame, regnum)
350 REGISTER_TYPE(regnum)
354 FRAME_REGISTER_INFO (frame, ...)
357 If nothing else rename this so that
358 how it relates to rawreg and the
362 The size of the cache can be computed
367 Restructure gdb directory tree so that it avoids any 8.3 and 14
372 Convert GDB build process to AUTOMAKE.
374 See also sub-directory configure below.
376 The current convention is (kind of) to use $(<header>_h) in all
377 dependency lists. It isn't done in a consistent way.
381 GDB 5.2 - Known Problems
382 ========================
386 Code Cleanups: General
387 ======================
389 The following are more general cleanups and fixes. They are not tied
390 to any specific release.
394 Investigate changing --target=a29k-amd-udi to a29k-*-coff* and
395 rationalize *.mt files. The got-ya is in remote-eb.c - it has its own
396 custom tty manipulation - it should be using the serial object.
400 Rename read_register{,_pid}() to read_unsigned_register{,_pid}().
404 Can't build IRIX -> arm GDB.

416 Problem with weak functions
417 http://sourceware.cygnus.com/ml/gdb/2000-05/msg00060.html

428 Follow through `make check' with --enable-shared.
430 When the srcware tree is configured with --enable-shared, the `expect'
431 program won't run properly. Jim Wilson found out gdb has a local hack
432 to set LD_LIBRARY_PATH, but, AFAIK, no other project has been hacked
435 http://sourceware.cygnus.com/ml/gdb/2000-q1/msg00845.html
439 Delete macro TARGET_BYTE_ORDER_SELECTABLE.
441 Patches in the database.
445 printcmd.c (print_address_numeric):
447 NOTE: This assumes that the significant address information is kept in
448 the least significant bits of ADDR - the upper bits were either zero
449 or sign extended. Should ADDRESS_TO_POINTER() or some
450 ADDRESS_TO_PRINTABLE() be used to do the conversion?
454 The BFD directory requires bug-fixed AUTOMAKE et.al.
456 AUTOMAKE 1.4 incorrectly set the TEXINPUTS environment variable. It
457 contained the full path to texinfo.tex when it should have only
458 contained the directory. The bug has been fixed in the current
459 AUTOMAKE sources. Automake snapshots can be found in:
460 ftp://sourceware.cygnus.com/pub/gdb/snapshots
461 and ftp://sourceware.cygnus.com/pub/binutils
465 Find something better than DEFAULT_BFD_ARCH, DEFAULT_BFD_VEC to
466 determine the default isa/byte-order.
470 Rely on BFD_BIG_ENDIAN and BFD_LITTLE_ENDIAN instead of host dependent
471 BIG_ENDIAN and LITTLE_ENDIAN.
475 Eliminate more compiler warnings.
477 Of course there also needs to be the usual debate over which warnings
478 are valid and how to best go about this.
480 One method: choose a single option; get agreement that it is
481 reasonable; try it out to see if there isn't anything silly about it
482 (-Wunused-parameters is an example of that) then incrementally hack
485 The other method is to enable all warnings and eliminate them from one
490 Elimination of ``(catch_errors_ftype *) func''.
492 Like make_cleanup_func it isn't portable.

506 [PATCH/5] src/intl/Makefile.in:distclean additions
507 http://sourceware.cygnus.com/ml/gdb-patches/2000-04/msg00363.html
509 Do not forget to merge the patch back into the trunk.
513 Rationalize the host-endian code (grep for HOST_BYTE_ORDER).
515 At present defs.h includes <endian.h> (which is linux specific) yet
516 almost nothing depends on it. Suggest "gdb_endian.h" which can also
517 handle <machine/endian.h> and only include that where it is really
522 Replace savestring() with something from libiberty.
524 An xstrldup()? but that would have different semantics.
528 Rationalize use of floatformat_unknown in GDB sources.
530 Instead of defaulting to floatformat_unknown, should hosts/targets
531 specify the value explicitly?
533 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00447.html
537 Add a ``name'' member to include/floatformat.h:struct floatformat.
538 Print that name in gdbarch.c.
542 Sort out the harris mess in include/floatformat.h (it hardwires two
543 different floating point formats).
547 See of the GDB local floatformat_do_doublest() and libiberty's
548 floatformat_to_double (which was once GDB's ...) can be merged some
553 Eliminate mmalloc(), mstrsave() et.al. from GDB.
555 Also eliminate it from defs.h.
559 Eliminate PTR. ISO-C allows ``void *''.
565 GDB should never abort. GDB should either throw ``error ()'' or
566 ``internal_error ()''. Better still GDB should naturally unwind with
571 GDB probably doesn't build on FreeBSD pre 2.2.x
572 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00378.html
574 Fixes to get FreeBSD working on 2.2.x, 3.x and 4.x caused the code to
579 Deprecate "fg". Apparently ``fg'' is actually continue.
581 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00417.html
585 Deprecate current use of ``floatformat_unknown''.
587 Require all targets to explicitly provide their float format instead
588 of defaulting to floatformat unknown. Doing the latter leads to nasty
591 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00447.html
595 Rationalize floatformat_to_double() vs floatformat_to_doublest().
597 Looks like GDB migrated floatformat_to_double() to libiberty but then
598 turned around and created a ..._to_doublest() the latter containing
601 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00472.html
605 Move floatformat_ia64_ext to libiberty/include floatformat.[ch].
607 http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00466.html
611 The ``maintenance deprecate set endian big'' command doesn't notice
612 that it is deprecating ``set endian'' and not ``set endian big'' (big
613 is implemented using an enum). Is anyone going to notice this?
617 When tab expanding something like ``set arch<tab>'' ignore the
618 deprecated ``set archdebug'' and expand to ``set architecture''.
622 Eliminate ``arm_register_names[j] = (char *) regnames[j]'' and the
623 like from arm-tdep.c.
627 Fix uses of ->function.cfunc = set_function().
629 The command.c code calls sfunc() when a set command. Rather than
630 change it suggest fixing the callback function so that it is more
633 http://sourceware.cygnus.com/ml/gdb-patches/2000-06/msg00062.html
635 See also ``Fix implementation of ``target xxx''.'' below.
639 IRIX 3.x support is probably broken.
643 Delete sim/SIM_HAVE_BREAKPOINTS and gdb/SIM_HAS_BREAKPOINTS.
644 http://sourceware.cygnus.com/ml/gdb-patches/2000-07/msg00042.html
646 Apart from the d30v, are there any sim/common simulators that make use
649 A brief summary of what happened is that sim/common/sim-break.c was
650 created as a good idea. It turned out a better idea was to use
651 SIM_SIGBREAK and have GDB pass back sim_resume (..., SIGBREAK).
655 Move remote_remove_hw_breakpoint, remote_insert_hw_breakpoint,
656 remote_remove_watchpoint, remote_insert_watchpoint into target vector.
660 Eliminate ``extern'' from C files.
664 Replace ``STREQ()'' et.al. with ``strcmp() == 0'' et.al.
666 Extreme care is recommeded - perhaps only modify tests that are
667 exercised by the testsuite (as determined using some type of code
672 Replace the file gdb/CONTRIBUTE with a file that is generated from the
673 gdb/doc/*.texinfo directory.
677 New Features and Fixes
678 ======================
680 These are harder than cleanups but easier than work involving
681 fundamental architectural change.
685 Hardware watchpoint problems on x86 OSes, including Linux:
687 1. Delete/disable hardware watchpoints should free hardware debug
689 2. Watch for different values on a viariable with one hardware debug
694 These are not GDB/ia32 issues per se: the above features are all
695 implemented in the DJGPP port of GDB and work in v5.0. Every
696 x86-based target should be able to lift the relevant parts of
697 go32-nat.c and use them almost verbatim. You get debug register
698 sharing through reference counts, and the ability to watch large
699 regions (up to 16 bytes) using multiple registers. (The required
700 infrastructure in high-level GDB application code, mostly in
701 breakpoint.c, is also working since v5.0.)
705 Add built-by, build-date, tm, xm, nm and anything else into gdb binary
706 so that you can see how the GDB was created.
710 Add an "info bfd" command that displays supported object formats,
711 similarly to objdump -i.
713 Is there a command already?
717 Fix ``I'm sorry, Dave, I can't do that.'' from symfile.c.
719 This requires internationalization.
725 (gdb) p fwprintf(stdout,L"%S\n", f)
726 No symbol "L" in current context.
730 Cleanup configury support for optional sub-directories.
732 Check how GCC handles multiple front ends for an example of how things
733 could work. A tentative first step is to rationalize things so that
734 all sub directories are handled in a fashion similar to gdb/mi.
736 See also automake above.
740 Add a transcript mechanism to GDB.
742 Such a mechanism might log all gdb input and output to a file in a
743 form that would allow it to be replayed. It could involve ``gdb
744 --transcript=FILE'' or it could involve ``(gdb) transcript file''.
748 Can the xdep files be replaced by autoconf?
752 Document trace machinery
756 Document ui-out and ui-file.
758 http://sourceware.cygnus.com/ml/gdb/2000-04/msg00121.html
762 Update texinfo.tex to latest?
766 Incorporate agentexpr.texi into gdb.texinfo
768 agentexpr.texi mostly describes the details of the byte code used for
769 tracepoints, not the internals of the support for this in GDB. So it
770 looks like gdb.texinfo is a better place for this information.
772 http://sourceware.cygnus.com/ml/gdb-patches/2000-04/msg00566.html
776 Document overlay machinery.
780 ``(gdb) catch signal SIGNAL''
782 Overlaps with ``handle SIGNAL'' but the implied behavior is different.
783 You can attach commands to a catch but not a handle. A handle has a
784 limited number of hardwired actions.
790 o readline/*.h bitrot
792 The TUI isn't up-to-date with
793 respect to the readline currently
794 bundled with GDB. Importing a
795 new readline is on the 5.1 wish
796 list so this can only get worse.
798 Grep for things like term_cursor_move.
800 (To be honest, I don't see anyone
801 importing a new readline before 5.1 is
804 o tui.c:va_catch_errors() bitrot
806 This nasty piece of work used knowledge
807 of the internals of GDBs error functions :-(
808 Ever since those internals were cleaned
809 up this code has been broken. :-(
811 o tuiWin.c:c_makeVisibleWithNewHeight() broken
812 tuiLayout.c:_extractDisplayStartAddr() broken
814 Both these function call find_line_pc()
815 incorrectly (wrong args, wrong return value).
817 I suspect this bug has always been there!
818 It had been hidden because those files
819 didn't include the necessary header files
822 o tuiRegs() host dependant
824 Not suprisingly, this isn't a very portable
825 section of code. However, I'm sure people
826 could live with no regs in the short to
829 o defs.h: #include "tui.h" et.al.
831 I'm not sure where this came from.
832 It was a really bad idea.
834 To get things to compile I did a nasty
835 hack (Just declare what was needed and
836 replace any expressions like xx->y.z()
837 in GDB proper with function calls). I
838 could commit it slightly cleaned up if
841 Medium Term. the #ifdef TUI and TuiDo()
842 should be changed to hooks (like GDBTK).
843 The gdb-events.[hc] is there for that
846 o tui.c:_tuiReset() host dependant
848 tui.c contains a lump of termio[s]
849 I suspect an equivalent block of
850 code can be lifted from readline.
851 An equivalent readline function may
854 o curses.h vs ncurses.h.
856 Simple portability problem.
860 This function is a mystery - where is it?
862 o tui-file.[hc] cleanup
864 This can be significantly simplified.
866 o The code should be pacified. (-Werror -W...)
868 There are plenty of #includes,
869 duplicate #includes, missing function decls
872 Some of the problems I found were through
873 fixing a few of the warnings.
875 o The code should be GNUtified.
877 It would be very nice to have this code
878 look like the rest of GDB. That way people
879 would be more accepting of it as a true
882 Until it is GNUtified it is going to stick
883 out like a sore thumb to the programmer.
885 o The code should be clearly copyrighted

892 Add support for ``gdb -cmd=...''
894 Along with many variations. Check:

926 The "ocd reset" command needs to flush the dcache, which requires breaking
927 the abstraction layer between the target independent and target code. One
928 way to address this is provide a generic "reset" command and target vector.

939 Generic: lin-thread cannot handle thread exit (Mark Kettenis, Michael

942 The thread_db assisted debugging code doesn't handle exiting threads
943 properly, at least in combination with glibc 2.1.3 (the framework is
944 there, just not the actual code). There are at least two problems

989 New languages come onto the scene all the time.
993 Re: Various C++ things
995 value_headof/value_from_vtable_info are worthless, and should be
996 removed. The one place in printcmd.c that uses it should use the RTTI
999 RTTI for g++ should be using the typeinfo functions rather than the
1000 vtables. The typeinfo functions are always at offset 4 from the
1001 beginning of the vtable, and are always right. The vtables will have
1002 weird names like E::VB sometimes. The typeinfo function will always
1003 be "E type_info function", or somesuch.
1005 value_virtual_fn_field needs to be fixed so there are no failures for
1006 virtual functions for C++ using g++.
1008 Testsuite cases are the major priority right now for C++ support,
1009 since i have to make a lot of changes that could potentially break

1020 Remote Protocol Support
1021 =======================
1025 Revised UDP support (was: Re: [Fwd: [patch] UDP transport support])
1026 http://sourceware.cygnus.com/ml/gdb-patches/2000-04/msg00000.html
1028 (Broken) support for GDB's remote protocol across UDP is to be
1029 included in the follow-on release.
1031 It should be noted that UDP can only work when the [Gg] packet fits in
1032 a single UDP packet.
1034 There is also much debate over the merit of this.
1038 Migrate qfThreadInfo packet -> qThreadInfo. (Andrew Cagney)
1040 Add support for packet enable/disable commands with these thread
1041 packets. General cleanup.

1053 Too much feedback to mention needs to be merged in (901660). Search
1054 for the word ``remote''.

1063 GDB doesn't recover gracefully from remote protocol errors.
1065 GDB wasn't checking for NAKs from the remote target. Instead a NAK is
1066 ignored and a timeout is required before GDB retries. A pre-cursor to
1067 fixing this this is making GDB's remote protocol packet more robust.
1069 While downloading to a remote protocol target, gdb ignores packet
1070 errors in so far as it will continue to download with chunk N+1 even
1071 if chunk N was not correctly sent. This causes gdb.base/remote.exp to
1072 take a painfully long time to run. As a PS that test needs to be
1073 fixed so that it builds on 16 bit machines.
1077 Fix the ``!'' packet.
1079 JT reported that the existing targets do, in fact return ``OK'' so it
1080 is possible to merge remote and extended-remote targets.
1084 Drop ``<address>'' from the [SsCc] packets.
1086 I don't think that GDB generates them so having it in the protocol is
1091 Fix doco on the ``q'' packet.
1093 It has evolved into a generic RPC. The notes should reflect this and,
1094 perhaps, the ``Q'' packet can be deprecated.
1096 The doco should mention that ``OK'' is a valid packet response.
1098 The doco should explain why ``OK'' needs to be a valid packet

1109 Resolve how to scale things to support very large packets.
1113 Resolve how to handle a target that changes things like its endianess
1114 on the fly - should it be returned in the ``T'' packet?
1116 Underlying problem is that the register file is target endian. If the
1117 target endianess changes gdb doesn't know.
1124 If / when GDB starts to support the debugging of multi-processor
1125 (rather than multi-thread) applications the symtab code will need to
1126 be updated a little so that several independent symbol tables are
1127 active at a given time.
1129 The other interesting change is a clarification of the exact meaning
1130 of CORE_ADDR and that has had consequences for a few targets (that
1131 were abusing that data type).

1167 There are never to many testcases.
1171 Better thread testsuite.
1175 Better C++ testsuite.
1179 Look at adding a GDB specific testsuite directory so that white box
1180 tests of key internals can be added (eg ui_file).
1184 Separate out tests that involve the floating point (FP).
1186 (Something for people brining up new targets). FP and non-fp tests
1187 are combined. I think there should be set of basic tests that
1188 exercise pure integer support and then a more expanded set that
1189 exercise FP and FP/integer interactions.
1191 As an example, the MIPS, for n32 as problems with passing FP's and
1192 structs. Since most inferior call tests include FP it is difficult to
1193 determine of the integer tests are ok.
1197 Architectural Changes: General
1198 ==============================
1200 These are harder than simple cleanups / fixes and, consequently
1201 involve more work. Typically an Architectural Change will be broken
1202 down into a more digestible set of cleanups and fixes.
1206 Cleanup software single step.
1208 At present many targets implement software single step by directly
1209 blatting memory (see rs6000-tdep.c). Those targets should register
1210 the applicable breakpoints using the breakpoint framework. Perhaphs a
1211 new internal breakpoint class ``step'' is needed.
1215 Replace READ_FP() with FRAME_HANDLE().
1217 READ_FP() is a hangover from the days of the vax when the ABI really
1218 did have a frame pointer register. Modern architectures typically
1219 construct a virtual frame-handle from the stack pointer and various
1220 other bits of string.
1222 Unfortunately GDB still treats this synthetic FP register as though it
1223 is real. That in turn really confuses users (arm and ``print $fp'' VS
1224 ``info registers fp''). The synthetic FP should be separated out of
1225 the true register set presented to the user.
1229 Register Cache Cleanup (below from Andrew Cagney)
1231 I would depict the current register architecture as something like:
1233 High GDB --> Low GDB
1238 register + REGISTER_BYTE(reg_nr)
1241 -------------------------
1242 | extern register[] |
1243 -------------------------
1245 where neither the high (valops.c et.al.) or low gdb (*-tdep.c) are
1246 really clear on what mechanisms they should be using to manipulate that
1247 buffer. Further, much code assumes, dangerously, that registers are
1248 contigious. Having got mips-tdep.c to support multiple ABIs, believe
1249 me, that is a bad assumption. Finally, that register cache layout is
1250 determined by the current remote/local target and _not_ the less
1251 specific target ISA. In fact, in many cases it is determined by the
1252 somewhat arbitrary layout of the [gG] packets!
1255 How I would like the register file to work is more like:
1283 The main objectives being:
1285 o a clear separation between the low
1286 level target and the high level GDB
1288 o a mechanism that solves the general
1289 problem of register aliases, overlaps
1290 etc instead of treating them as optional
1291 extras that can be wedged in as an after
1292 thought (that is a reasonable description
1293 of the current code).
1295 Identify then solve the hard case and the
1296 rest just falls out. GDB solved the easy
1297 case and then tried to ignore the real
1300 o a removal of the assumption that the
1301 mapping between the register cache
1302 and virtual registers is largely static.
1303 If you flip the USR/SSR stack register
1304 select bit in the status-register then
1305 the corresponding stack registers should
1308 o a mechanism that clearly separates the
1309 gdb internal register cache from any
1310 target (not architecture) dependent
1311 specifics such as [gG] packets.
1313 Of course, like anything, it sounds good in theory. In reality, it
1314 would have to contend with many<->many relationships at both the
1315 virt<->cache and cache<->target level. For instance:
1318 Modifying an mmx register may involve
1319 scattering values across both FP and
1320 mmpx specific parts of a buffer
1323 When writing back a SP it may need to
1324 both be written to both SP and USP.
1329 Rather than let this like the last time it was discussed, just slip, I'm
1330 first going to add this e-mail (+ references) to TODO. I'd then like to
1331 sketch out a broad strategy I think could get us there.
1334 First thing I'd suggest is separating out the ``extern registers[]''
1335 code so that we can at least identify what is using it. At present
1336 things are scattered across many files. That way we can at least
1337 pretend that there is a cache instead of a global array :-)
1339 I'd then suggest someone putting up a proposal for the pseudo-reg /
1340 high-level side interface so that code can be adopted to it. For old
1341 code, initially a blanket rename of write_register_bytes() to
1342 deprecated_write_register_bytes() would help.
1344 Following that would, finaly be the corresponding changes to the target.
1348 Check that GDB can handle all BFD architectures (Andrew Cagney)
1350 There should be a test that checks that BFD/GDB are in sync with
1351 regard to architecture changes. Something like a test that first
1352 queries GDB for all supported architectures and then feeds each back
1353 to GDB.. Anyone interested in learning how to write tests? :-)
1357 Architectural Change: Multi-arch et al.
1358 =======================================
1360 The long term objective is to remove all assumptions that there is a
1361 single target with a single address space with a single instruction
1362 set architecture and single application binary interface.
1364 This is an ongoing effort. The first milestone is to enable
1365 ``multi-arch'' where by all architectural decisions are made at
1368 It should be noted that ``gdbarch'' is really ``gdbabi'' and
1369 ``gdbisa''. Once things are multi-arched breaking that down correctly
1370 will become much easier.
1374 GDBARCH cleanup (Andrew Cagney)
1376 The non-generated parts of gdbarch.{sh,h,c} should be separated out
1377 into arch-utils.[hc].
1379 Document that gdbarch_init_ftype could easily fail because it didn't
1380 identify an architecture.
1384 Fix BELIEVE_PPC_PROMOTION. Change it to BELIEVE_PPC_PROMOTION_P?
1386 At present there is still #ifdef BELIEVE_PPC_PROMOTION code in the
1391 Fix target_signal_from_host() etc.
1393 The name is wrong for starters. ``target_signal'' should probably be
1394 ``gdb_signal''. ``from_host'' should be ``from_target_signal''.
1395 After that it needs to be multi-arched and made independent of any
1396 host signal numbering.
1400 Update ALPHA so that it uses ``struct frame_extra_info'' instead of
1403 This is a barrier to replacing mips_extra_func_info with something
1404 that works with multi-arch.
1408 Multi-arch mips_extra_func_info.
1410 This first needs the alpha to be updated so that it uses ``struct
1415 Rationalize TARGET_SINGLE_FORMAT and TARGET_SINGLE_BIT et al.
1417 Surely one of them is redundant.
1421 Convert ALL architectures to MULTI-ARCH.
1425 Select the initial multi-arch ISA / ABI based on --target or similar.
1427 At present the default is based on what ever is first in the BFD
1428 archures table. It should be determined based on the ``--target=...''
1433 Make MIPS pure multi-arch.
1435 It is only at the multi-arch enabled stage.
1441 Enable the code to recognize --enable-targets=.... like BINUTILS does.
1443 Can the tm.h and nm.h files be eliminated by multi-arch.
1447 Architectural Change: MI, LIBGDB and scripting languages
1448 ========================================================
1450 See also architectural changes related to the event loop. LIBGDB
1451 can't be finished until there is a generic event loop being used by
1454 The long term objective is it to be possible to integrate GDB into
1455 scripting languages.
1459 Implement generic ``(gdb) commmand > file''
1461 Once everything is going through ui_file it should be come fairly
1464 http://sourceware.cygnus.com/ml/gdb/2000-04/msg00104.html
1468 Replace gdb_stdtarg with gdb_targout (and possibly gdb_targerr).
1470 gdb_stdtarg is easily confused with gdb_stdarg.
1474 Extra ui_file methods - dump.
1476 Very useful for whitebox testing.
1480 Eliminate error_begin().
1482 With ui_file, there is no need for the statefull error_begin ()
1487 Send normal output to gdb_stdout.
1488 Send error messages to gdb_stderror.
1489 Send debug and log output log gdb_stdlog.
1491 GDB still contains many cases where (f)printf or printf_filtered () is
1492 used when it should be sending the messages to gdb_stderror or
1493 gdb_stdlog. The thought of #defining printf to something has crossed
1498 Re-do GDB's output pager.
1500 GDB's output pager still relies on people correctly using *_filtered
1501 for gdb_stdout and *_unfiltered for gdb_stdlog / gdb_stderr.
1502 Hopefully, with all normal output going to gdb_stdout, the pager can
1503 just look at the ui_file that the output is on and then use that to
1504 decide what to do about paging. Sounds good in theory.
1508 Check/cleanup MI documentation.
1510 The list of commands specified in the documentation needs to be
1511 checked against the mi-cmds.c table in a mechanical way (so that they
1512 two can be kept up-to-date).
1516 Convert MI into libgdb
1518 MI provides a text interface into what should be many of the libgdb
1519 functions. The implementation of those functions should be separated
1520 into the MI interface and the functions proper. Those functions being
1521 moved to gdb/lib say.
1527 The first part can already be found in defs.h.
1531 MI's input does not use buffering.
1533 At present the MI interface reads raw characters of from an unbuffered
1534 FD. This is to avoid several nasty buffer/race conditions. That code
1535 should be changed so that it registers its self with the event loop
1536 (on the input FD) and then push commands up to MI as they arrive.
1538 The serial code already does this.
1542 Make MI interface accessible from existing CLI.
1546 Add a breakpoint-edit command to MI.
1548 It would be similar to MI's breakpoint create but would apply to an
1549 existing breakpoint. It saves the need to delete/create breakpoints
1550 when ever they are changed.
1554 Add directory path to MI breakpoint.
1556 That way the GUI's task of finding the file within which the
1557 breakpoint was set is simplified.
1561 Add a mechanism to reject certain expression classes to MI
1563 There are situtations where you don't want GDB's expression
1564 parser/evaluator to perform inferior function calls or variable
1565 assignments. A way of restricting the expression parser so that such
1566 operations are not accepted would be very helpful.
1570 Remove sideffects from libgdb breakpoint create function.
1572 The user can use the CLI to create a breakpoint with partial
1573 information - no file (gdb would use the file from the last
1576 The libgdb interface currently affects that environment which can lead
1577 to confusion when a user is setting breakpoints via both the MI and
1580 This is also a good example of how getting the CLI ``right'' will be
1585 Move gdb_lasterr to ui_out?
1587 The way GDB throws errors and records them needs a re-think. ui_out
1588 handles the correct output well. It doesn't resolve what to do with
1589 output / error-messages when things go wrong.
1593 do_setshow_command contains a 1024 byte buffer.
1595 The function assumes that there will never be any more than 1024 bytes
1596 of enum. It should use mem_file.
1600 Should struct cmd_list_element . completer take the command as an
1605 Should the bulk of top.c:line_completion_function() be moved to
1606 command.[hc]? complete_on_cmdlist() and complete_on_enums() could
1607 then be made private.
1611 top.c (execute_command): Should a command being valid when the target
1612 is running be made an attribute (predicate) to the command rather than
1613 an explicit set of tests.
1617 top.c (execute_command): Should the bulk of this function be moved
1618 into command.[hc] so that top.c doesn't grub around in the command
1623 Architectural Change: Async
1624 ===========================
1626 While GDB uses an event loop when prompting the user for input. That
1627 event loop is not exploited by targets when they allow the target
1628 program to continue. Typically targets still block in (target_wait())
1629 until the program again halts.
1631 The closest a target comes to supporting full asynchronous mode are
1632 the remote targets ``async'' and ``extended-async''.
1636 Asynchronous expression evaluator
1638 Inferior function calls hang GDB.
1642 Fix implementation of ``target xxx''.
1644 At present when the user specifies ``target xxxx'', the CLI maps that
1645 directly onto a target open method. It is then assumed that the
1646 target open method should do all sorts of complicated things as this
1647 is the only chance it has. Check how the various remote targets
1648 duplicate the target operations. Check also how the various targets
1649 behave differently for purely arbitrary reasons.
1651 What should happen is that ``target xxxx'' should call a generic
1652 ``target'' function and that should then co-ordinate the opening of
1653 ``xxxx''. This becomes especially important when you're trying to
1654 open an asynchronous target that may need to perform background tasks
1655 as part of the ``attach'' phase.
1657 Unfortunately, due to limitations in the old/creaking command.h
1658 interface, that isn't possible. The function being called isn't told
1659 of the ``xxx'' or any other context information.
1661 Consequently a precursor to fixing ``target xxxx'' is to clean up the
1662 CLI code so that it passes to the callback function (attatched to a
1663 command) useful information such as the actual command and a context
1664 for that command. Other changes such as making ``struct command''
1665 opaque may also help.
1668 http://sourceware.cygnus.com/ml/gdb-patches/2000-06/msg00062.html
1672 Make "target xxx" command interruptible.
1674 As things become async this becomes possible. A target would start
1675 the connect and then return control to the event loop. A cntrl-c
1676 would notify the target that the operation is to be abandoned and the
1677 target code could respond.
1681 Add a "suspend" subcommand of the "continue" command to suspend gdb
1682 while continuing execution of the subprocess. Useful when you are
1683 debugging servers and you want to dodge out and initiate a connection
1684 to a server running under gdb.
1693 Frequently requested but not approved requests.
1697 Eliminate unused argument warnings using ATTRIBUTE_UNUSED.
1699 The benefits on this one are thought to be marginal - GDBs design
1700 means that unused parameters are very common. GCC 3.0 will also
1701 include the option -Wno-unused-parameter which means that ``-Wall
1702 -Wno-unused-parameters -Werror'' can be specified.
1711 This list is not up to date, and opinions vary about the importance or
1712 even desirability of some of the items. If you do fix something, it
1713 always pays to check the below.
1717 @c This does not work (yet if ever). FIXME.
1718 @c @item --parse=@var{lang} @dots{}
1719 @c Configure the @value{GDBN} expression parser to parse the listed languages.
1720 @c @samp{all} configures @value{GDBN} for all supported languages. To get a
1721 @c list of all supported languages, omit the argument. Without this
1722 @c option, @value{GDBN} is configured to parse all supported languages.
1726 START_INFERIOR_TRAPS_EXPECTED need never be defined to 2, since that
1727 is its default value. Clean this up.
1731 It should be possible to use symbols from shared libraries before we know
1732 exactly where the libraries will be loaded. E.g. "b perror" before running
1733 the program. This could maybe be done as an extension of the "breakpoint
1734 re-evaluation" after new symbols are loaded.
1738 Make single_step() insert and remove breakpoints in one operation.
1740 [If this is talking about having single_step() insert the breakpoints,
1741 run the target then pull the breakpoints then it is wrong. The
1742 function has to return as control has to eventually be passed back to
1743 the main event loop.]
1747 Speed up single stepping by avoiding extraneous ptrace calls.
1751 Speed up single stepping by not inserting and removing breakpoints
1752 each time the inferior starts and stops.
1754 Breakpoints should not be inserted and deleted all the time. Only the
1755 one(s) there should be removed when we have to step over one. Support
1756 breakpoints that don't have to be removed to step over them.
1758 [this has resulted in numerous debates. The issue isn't clear cut]
1762 Provide "voodoo" debugging of core files. This creates a zombie
1763 process as a child of the debugger, and loads it up with the data,
1764 stack, and regs of the core file. This allows you to call functions
1765 in the executable, to manipulate the data in the core file.
1771 GDB reopens the source file on every line, as you "next" through it.
1773 [still true? I've a memory of this being fixed]
1777 Perhaps "i source" should take an argument like that of "list".
1781 Remove "at 0xnnnn" from the "b foo" response, if `print address off' and if
1782 it matches the source line indicated.
1786 The prompt at end of screen should accept space as well as CR.
1790 Backtrace should point out what the currently selected frame is, in
1791 its display, perhaps showing "@3 foo (bar, ...)" or ">3 foo (bar,
1792 ...)" rather than "#3 foo (bar, ...)".
1796 "i program" should work for core files, and display more info, like what
1797 actually caused it to die.
1801 "x/10i" should shorten the long name, if any, on subsequent lines.
1805 "next" over a function that longjumps, never stops until next time you happen
1806 to get to that spot by accident. E.g. "n" over execute_command which has
1811 "set zeroprint off", don't bother printing members of structs which
1812 are entirely zero. Useful for those big structs with few useful
1817 GDB does four ioctl's for every command, probably switching terminal modes
1818 to/from inferior or for readline or something.
1822 terminal_ours versus terminal_inferior: cache state. Switch should be a noop
1823 if the state is the same, too.
1827 "i frame" shows wrong "arglist at" location, doesn't show where the args
1828 should be found, only their actual values.
1832 There should be a way for "set" commands to validate the new setting
1833 before it takes effect.
1837 "ena d" is ambiguous, why? "ena delete" seems to think it is a command!
1841 i line VAR produces "Line number not known for symbol ``var''.". I
1842 thought we were stashing that info now!
1846 We should be able to write to random files at hex offsets like adb.
1850 [elena - delete this]
1852 Handle add_file with separate text, data, and bss addresses. Maybe
1853 handle separate addresses for each segment in the object file?
1857 [Jimb/Elena delete this one]
1859 Handle free_named_symtab to cope with multiply-loaded object files
1860 in a dynamic linking environment. Should remember the last copy loaded,
1861 but not get too snowed if it finds references to the older copy.
1865 [elena delete this also]
1867 Remove all references to:
1874 now that we have BFD. All remaining are in machine dependent files.
1878 Re-organize help categories into things that tend to fit on a screen
1883 Add in commands like ADB's for searching for patterns, etc. We should
1884 be able to examine and patch raw unsymboled binaries as well in gdb as
1885 we can in adb. (E.g. increase the timeout in /bin/login without source).
1887 [actually, add ADB interface :-]
1891 When doing "step" or "next", if a few lines of source are skipped between
1892 the previous line and the current one, print those lines, not just the
1893 last line of a multiline statement.
1897 Handling of "&" address-of operator needs some serious overhaul
1898 for ANSI C and consistency on arrays and functions.
1899 For "float point[15];":
1900 ptype &point[4] ==> Attempt to take address of non-lvalue.
1901 For "char *malloc();":
1902 ptype malloc ==> "char *()"; should be same as
1903 ptype &malloc ==> "char *(*)()"
1904 call printf ("%x\n", malloc) ==> weird value, should be same as
1905 call printf ("%x\n", &malloc) ==> correct value
1909 Fix dbxread.c symbol reading in the presence of interrupts. It
1910 currently leaves a cleanup to blow away the entire symbol table when a
1911 QUIT occurs. (What's wrong with that? -kingdon, 28 Oct 1993).
1913 [I suspect that the grype was that, on a slow system, you might want
1914 to cntrl-c and get just half the symbols and then load the rest later
1915 - scary to be honest]
1919 Mipsread.c reads include files depth-first, because the dependencies
1920 in the psymtabs are way too inclusive (it seems to me). Figure out what
1921 really depends on what, to avoid recursing 20 or 30 times while reading
1926 value_add() should be subtracting the lower bound of arrays, if known,
1927 and possibly checking against the upper bound for error reporting.
1931 When listing source lines, check for a preceding \n, to verify that
1932 the file hasn't changed out from under us.
1934 [fixed by some other means I think. That hack wouldn't actually work
1935 reliably - the file might move such that another \n appears. ]
1939 Get all the remote systems (where the protocol allows it) to be able to
1940 stop the remote system when the GDB user types ^C (like remote.c
1941 does). For ebmon, use ^Ak.
1945 Possible feature: A version of the "disassemble" command which shows
1946 both source and assembly code ("set symbol-filename on" is a partial
1949 [has this been done? It was certainly done for MI and GDBtk]
1953 investigate "x/s 0" (right now stops early) (I think maybe GDB is
1954 using a 0 address for bad purposes internally).
1958 Make "info path" and path_command work again (but independent of the
1959 environment either of gdb or that we'll pass to the inferior).
1963 Make GDB understand the GCC feature for putting octal constants in
1964 enums. Make it so overflow on an enum constant does not error_type
1965 the whole type. Allow arbitrarily large enums with type attributes.
1966 Put all this stuff in the testsuite.
1970 Make TYPE_CODE_ERROR with a non-zero TYPE_LENGTH more useful (print
1971 the value in hex; process type attributes). Add this to the
1972 testsuite. This way future compilers can add new types and old
1973 versions of GDB can do something halfway reasonable.
1977 Fix mdebugread.c:parse_type to do fundamental types right (see
1978 rs6000_builtin_type in stabsread.c for what "right" is--the point is
1979 that the debug format fixes the sizes of these things and it shouldn't
1980 depend on stuff like TARGET_PTR_BIT and so on. For mdebug, there seem
1981 to be separate bt* codes for 64 bit and 32 bit things, and GDB should
1982 be aware of that). Also use a switch statement for clarity and speed.
1986 Investigate adding symbols in target_load--some targets do, some
1991 Put dirname in psymtabs and change lookup*symtab to use dirname (so
1992 /foo/bar.c works whether compiled by cc /foo/bar.c, or cd /foo; cc
1997 Merge xcoffread.c and coffread.c. Use breakpoint_re_set instead of
2002 Make a watchpoint which contains a function call an error (it is
2003 broken now, making it work is probably not worth the effort).
2007 New test case based on weird.exp but in which type numbers are not
2008 renumbered (thus multiply defining a type). This currently causes an
2009 infinite loop on "p v_comb".
2013 [Hey! Hint Hint Delete Delete!!!]
2015 Fix 386 floating point so that floating point registers are real
2016 registers (but code can deal at run-time if they are missing, like
2017 mips and 68k). This would clean up "info float" and related stuff.
2021 gcc -g -c enummask.c then gdb enummask.o, then "p v". GDB complains
2022 about not being able to access memory location 0.
2024 -------------------- enummask.c
2045 If try to modify value in file with "set write off" should give
2046 appropriate error not "cannot access memory at address 0x65e0".
2050 Allow core file without exec file on RS/6000.
2054 Make sure "shell" with no arguments works right on DOS.
2058 Make gdb.ini (as well as .gdbinit) be checked on all platforms, so
2059 the same directory can be NFS-mounted on unix or DOS, and work the
2064 [Is this another delete???]
2066 Get SECT_OFF_TEXT stuff out of objfile_relocate (might be needed to
2067 get RS/6000 to work right, might not be immediately relevant).
2071 Work out some kind of way to allow running the inferior to be done as
2072 a sub-execution of, eg. breakpoint command lists. Currently running
2073 the inferior interupts any command list execution. This would require
2074 some rewriting of wait_for_inferior & friends, and hence should
2075 probably be done in concert with the above.
2079 Add function arguments to gdb user defined functions.
2083 Add convenience variables that refer to exec file, symbol file,
2084 selected frame source file, selected frame function, selected frame
2089 Modify the handling of symbols grouped through BINCL/EINCL stabs to
2090 allocate a partial symtab for each BINCL/EINCL grouping. This will
2091 seriously decrease the size of inter-psymtab dependencies and hence
2092 lessen the amount that needs to be read in when a new source file is
2097 Add a command for searching memory, a la adb. It specifies size,
2098 mask, value, start address. ADB searches until it finds it or hits
2099 an error (or is interrupted).
2103 Remove the range and type checking code and documentation, if not
