* gdb.disasm/hppa.s (addib_tests): Fix typo.

[binutils.git] / gdb / testsuite / TODO

The highest priority item is not on this list: Fix bugs in the
existing testsuite, fix the GDB/compiler/shell/etc bugs which it
detects (particularly when they are hard to XFAIL), make it run
reliably without unexpected failures on the "standard" machines, etc.
This list exists largely as "tests we can add when we are ready to
risk destabilizing it again".

return.exp--reenable test (there is nothing known to be wrong with the
test, but it hasn't been tried on a wide range of architectures).

nodebug.exp--test printing variables.

Get crossload tests to use --with-targets and reenable them.

corefile.exp:
1.  Print variables from the core file (data and stack), and text
(from the exec file).  This tests whether the corefile sections are
mapped to the right addresses.
2.  Test what happens when we get a new exec file without explicitly
getting rid of the core file (we at least must avoid core dumps and such).
3.  Test backtrace in corefile.exp.
4.  Test ability to run program when there is a core target, then go
back to the core file when the program exits.

Test handling of floating point variables
1.  float, double, or long double
2.  in register or saved register or memory.  Also the case where a
double is in two float registers and only one of them is saved.
3.  print them or set them
4.  (Alpha) integer (32 or 64 bit) in floating point register.

Print registers--"p $r5", "p sizeof ($r5)".  Test that they print
appropriately (integer registers in decimal, registers which always
contain addresses (pc, probably sp and fp, maybe others) in hex,
floating point).

Test "info line" with all kinds of linespecs.  Test that the last line
of the file works right.

weird.exp--test that unrecognized cross-reference types or
unrecognized visibility or virtual characters get skipped properly
(see stabs.texinfo).

Test "jump" including jump to a breakpoint (the latter will need an
xfail for UDI and probably VxWorks (PR 1786 for vxworks; PR 2416
contains some info for 29k).

Test C++ nested types (especially if PR 1954 is fixed; even if not
*some* things already should work even in the presence of nested
types).  Test classes nested more than 9 levels deep (g++ mangles
these differently) (both a demangle test and some tests which also
test the compiler).  Test calling a method of a class nested more than
9 levels (for gdb_mangle_name and demangling).

Test that printing const-qualified versions of various types works.
In particular, on the sparc and probably other machines, "double" is
handled differently from most types because it requires more alignment
and thus goes in a different section (there is a gcc 2.4.5 bug with
"const double" on sparc).

Test that GDB's "source" command works and that things work if stdin
is redirected (to a file or a pipe).  Test user defined command.  Run
an inferior each of these ways (to test that inflow.c works).  Test
that GDB works if the last line of stdin or a source'd file lacks a
newline.

Test that module__2do (for example) in a C program does not get
demangled.

Test that unmatched single quotes produce error messages, both in
expressions and linespecs.

Test "cd".  "foo/bar/.." should get simplified to "foo".  "/../.."
should not get simplified (for Mach).  "/.." should not get simplified
(for other networked OSes; POSIX.1 section B.2.3.7).  All these
examples should continue to work with trailing slashes.

Test scoping; here is a start
 1	int i=2;
 2	int j=3;
 3	main()
 4	{
 5	    int i;
 6	    for (i=600; i>0; i--)
 7		print_line(i);
 8	}
 9
10	print_line(i)
11	    int i;
12	{
13	    h();
14	    printf("%d\n",i);
15	}
16
17	h()
18	{
19	    printf("In h...");
20	}
Set a breakpoint in h, and print i, print_line::i, and main::i.  Set a
breakpoint in main (or don't run the program), and test that
print_line::i is an error.  But if i were static, "p main::i" should
work even if the program is not being run.

Write a test for the reentracy bug with rs6000_struct_return_address
in rs6000-tdep.c.

Test "return" from dummy frames.

FORTRAN common blocks (a.out and xcoff--weird.exp has the start of
one but it is not quite right as of 19 Nov 1993).

Test that "x" command sets $_ and $__.  Test $_ in general.

Test ability to process NMAGIC a.out files.

If there are two breakpoints in the same place, and exactly one of
them has its condition true, test that the correct breakpoint gets
printed.

Set a watchpoint on a local variable (to be interesting, make a few
calls, to be more interesting, make a recursive call).  Test that it
gets disabled when leaving that scope.

Test calling a function, hitting a breakpoint in the called function,
calling another function, and hitting a breakpoint.  Test backtrace
works in the presence of multiple dummy frames.  Test that "continue"
will get you out of the inner called function, and "continue" again
will get you back to where you were when you called the first one.

Test special longjmp handling in wait_for_inferior (need to figure out
in detail what the proper behavior in each case is).  Test longjmp to
a place where there is a breakpoint (such that
BPSTAT_WHAT_CLEAR_LONGJMP_RESUME_SINGLE happens).  In general, test
interactions between longjmp and watchpoints, breakpoints, stepping,
call function, etc.

Test jumping right past a breakpoint (the case where wait_for_inferior
passes not_a_breakpoint to bpstat_stop_status).  Might already be
tested by some of the sun3 tests.  Probably want a .s test to avoid
compiler dependencies.

Test more obscure wait_for_inferior cases, expanding on the tests in
watchpoint.exp, signals.exp, etc.

Test that the copyright year in the startup message matches the
current year (would produce a single spurious FAIL on old GDB's, but
probably still a good idea).
