+ README for gdb-4.4 release
+ John Gilmore & Stu Grossman 31 Jan 1992
+
This is GDB, the GNU source-level debugger, presently running under un*x.
+A summary of new features is in the file `WHATS.NEW'.
-Before compiling GDB, you must tell GDB what kind of machine you are
-running on. To do this, type `config.gdb machine', where machine is
-something like `vax' or `sun2'. For a list of valid machine types,
-type `config.gdb'.
-Normally config.gdb edits the makefile as necessary. If you have to
-edit the makefile on a standard machine listed in config.gdb this
-should be considered a bug and reported as such.
+Unpacking and Installation -- quick overview
+==========================
-Once these files are set up, just `make' will do everything,
-producing an executable `gdb' in this directory.
+In this release, the GDB debugger sources, the generic GNU include
+files, the BFD ("binary file description") library, the readline library,
+and a miscellaneous library all have directories of their own underneath
+the gdb-4.4 directory. The idea is that a variety of GNU tools can
+share a common copy of these things. Configuration scripts and
+makefiles exist to cruise up and down this directory tree and
+automatically build all the pieces in the right order.
-If you want a new (current to this release) version of the manual, you
-will have to use the gdb.texinfo file provided with this distribution.
-The gdb.texinfo file requires the texinfo-format-buffer command from
-emacs 18.55 or later.
+When you unpack the gdb-4.4.tar.Z file, you'll get a directory called
+`gdb-4.4', which contains:
-About languages other than C...
+ DOC.configure bfd/ configure* glob/ readline/
+ Makefile.in config/ configure.in include/ texinfo/
+ README config.sub* gdb/ libiberty/
-C++ support has been integrated into gdb. GDB should work with Pascal
-and FORTRAN programs, but I am not aware of anyone who is working on
-getting it to use the syntax of any language other than C or C++.
+To build GDB, you can just do:
-About -gg format...
+ cd gdb-4.4
+ ./configure HOSTTYPE (e.g. sun4, decstation)
+ make
+ cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
-Currently GDB version 3.x does *not* support GCC's -gg format. This
-is because it is (in theory) has fast enough startup on dbx debugging
-format object files that -gg format is unnecessary (and hence
-undesirable, since it wastes space and processing power in gcc). I
-would like to hear people's opinions on the amount of time currently
-spent in startup; is it fast enough?
+This will configure and build all the libraries as well as GDB.
+If you get compiler warnings during this stage, see the `Reporting Bugs'
+section below; there are a few known problems.
-About remote debugging...
+GDB can be used as a cross-debugger, running on a machine of one type
+while debugging a program running on a machine of another type. See below.
-The two files remote-multi.shar and remote-sa.m68k.shar contain two
-examples of a remote stub to be used with remote.c. The the -multi
-file is a general stub that can probably be running on various
-different flavors of unix to allow debugging over a serial line from
-one machine to another. The remote-sa.m68k.shar is designed to run
-standalone on a 68k type cpu and communicate properley with the
-remote.c stub over a serial line.
-About reporting bugs...
+More Documentation
+==================
-The correct address for reporting bugs found with gdb is
+ The GDB 4 release includes an already-formatted reference card,
+ready for printing on a PostScript or GhostScript printer, in the `gdb'
+subdirectory of the main source directory--in `gdb-4.4/gdb/refcard.ps'
+of the version 4.4 release. If you have a PostScript or GhostScript
+printer, you can print the reference card by just sending `refcard.ps'
+to the printer.
-About xgdb...
+ If all you have is TeX, format the GDB reference card by typing:
-xgdb.c was provided to us by the user community; it is not an integral
-part of the gdb distribution. The problem of providing visual
-debugging support on top of gdb is peripheral to the GNU project and
-(at least right now) we can't afford to put time into it. So while we
-will be happy to incorporate user fixes to xgdb.c, we do not guarantee
-that it will work and we will not fix bugs reported in it. Someone is
-working on writing a new XGDB, so improving (e.g. by fixing it so that
-it will work, if it doesn't currently) the current one is not worth it.
+ make refcard.dvi
-For those intersted in auto display of source and the availability of
-an editor while debugging I suggest trying gdb-mode in gnu-emacs.
-Comments on this mode are welcome.
+ The GDB reference card is designed to print in landscape mode on US
+"letter" size paper; that is, on a sheet 11 inches wide by 8.5 inches
+high. You will need to specify this form of printing as an option to
+your DVI output program.
+
+ All the documentation for GDB comes as part of the online
+distribution. The documentation is written in Texinfo format,
+which is a documentation system that uses a single source file to
+produce both on-line information and a printed manual. You can use
+one of the Info formatting commands to create the on-line version of
+the documentation and TeX (or `texi2roff') to typeset the printed
+version.
+
+ GDB includes an already formatted copy of the on-line Info version
+of this manual in the `gdb' subdirectory. The main Info file is
+`gdb-VERSION-NUMBER/gdb/gdb.info', and it refers to subordinate files
+matching `gdb.info*' in the same directory.
+
+ If you want to format these Info files yourself, you need one of the
+Info formatting programs, such as `texinfo-format-buffer' or
+`makeinfo'.
+
+ If you have `makeinfo' installed, and are in the top level GDB
+source directory (`gdb-4.4', in the case of version 4.4), you can make
+the Info file by typing:
+
+ cd gdb
+ make gdb.info
+
+ If you want to typeset and print copies of this manual, you need
+TeX, a printing program such as `lpr', and `texinfo.tex', the Texinfo
+definitions file.
+
+ TeX is typesetting program; it does not print files directly, but
+produces output files called DVI files. To print a typeset document,
+you need a program to print DVI files. If your system has TeX
+installed, chances are it has such a program. The precise command to
+use depends on your system; `lpr -d' is common; another is `dvips'.
+The DVI print command may require a file name without any extension or
+a `.dvi' extension.
+
+ TeX also requires a macro definitions file called `texinfo.tex'.
+This file tells TeX how to typeset a document written in Texinfo
+format. On its own, TeX cannot read, much less typeset a Texinfo
+file. `texinfo.tex' is distributed with GDB and is located in the
+`gdb-VERSION-NUMBER/texinfo' directory.
+
+ If you have TeX and a DVI printer program installed, you can
+typeset and print this manual. First switch to the the `gdb'
+subdirectory of the main source directory (for example, to
+`gdb-4.4/gdb') and then type:
+
+ make gdb.dvi
+
+Installing GDB
+==============
+
+ GDB comes with a `configure' script that automates the process of
+preparing GDB for installation; you can then use `make' to build the
+`gdb' program.
+
+ The GDB distribution includes all the source code you need for GDB
+in a single directory, whose name is usually composed by appending the
+version number to `gdb'.
+
+ For example, the GDB version 4.4 distribution is in the `gdb-4.4'
+directory. That directory contains:
+
+`gdb-4.4/configure (and supporting files)'
+ script for configuring GDB and all its supporting libraries.
+
+`gdb-4.4/gdb'
+ the source specific to GDB itself
+
+`gdb-4.4/bfd'
+ source for the Binary File Descriptor Library
+
+`gdb-4.4/include'
+ GNU include files
+
+`gdb-4.4/libiberty'
+ source for the `-liberty' free software library
+
+`gdb-4.4/readline'
+ source for the GNU command-line interface
+
+ The simplest way to configure and build GDB is to run `configure'
+from the `gdb-VERSION-NUMBER' source directory, which in this example
+is the `gdb-4.4' directory.
+
+ First switch to the `gdb-VERSION-NUMBER' source directory if you
+are not already in it; then run `configure'. Pass the identifier for
+the platform on which GDB will run as an argument.
+
+ For example:
+
+ cd gdb-4.4
+ ./configure HOST
+ make
+
+where HOST is an identifier such as `sun4' or `decstation', that
+identifies the platform where GDB will run.
+
+ These `configure' and `make' commands build the three libraries `bfd',
+`readline', and `libiberty', then `gdb' itself. The configured source
+files, and the binaries, are left in the corresponding source
+directories.
+
+ `configure' is a Bourne-shell (`/bin/sh') script; if your system
+does not recognize this automatically when you run a different shell,
+you may need to run `sh' on it explicitly:
+
+ sh configure HOST
+
+ If you run `configure' from a directory that contains source
+directories for multiple libraries or programs, such as the `gdb-4.4'
+source directory for version 4.4, `configure' creates configuration
+files for every directory level underneath (unless you tell it not to,
+with the `--norecursion' option).
+
+ You can run the `configure' script from any of the subordinate
+directories in the GDB distribution, if you only want to configure
+that subdirectory; but be sure to specify a path to it.
+
+ For example, with version 4.4, type the following to configure only
+the `bfd' subdirectory:
+
+ cd gdb-4.4/bfd
+ ../configure HOST
+
+ You can install `gdb' anywhere; it has no hardwired paths.
+However, you should make sure that the shell on your path (named by
+the `SHELL' environment variable) is publicly readable. Remember that
+GDB uses the shell to start your program--some systems refuse to let
+GDB debug child processes whose programs are not readable.
+
+
+Compiling GDB in Another Directory
+==================================
+
+ If you want to run GDB versions for several host or target machines,
+you'll need a different `gdb' compiled for each combination of host
+and target. `configure' is designed to make this easy by allowing you
+to generate each configuration in a separate subdirectory, rather than
+in the source directory. If your `make' program handles the `VPATH'
+feature (GNU `make' does), running `make' in each of these directories
+then builds the `gdb' program specified there.
+
+ To build `gdb' in a separate directory, run `configure' with the
+`--srcdir' option to specify where to find the source. (Remember,
+you'll also need to specify a path to find `configure' itself from
+your working directory.)
+
+ For example, with version 4.4, you can build GDB in a separate
+directory for a Sun 4 like this:
+
+ cd gdb-4.4
+ mkdir ../gdb-sun4
+ cd ../gdb-sun4
+ ../gdb-4.4/configure --srcdir=../gdb-4.4 sun4
+ make
+
+ When `configure' builds a configuration using a remote source
+directory, it creates a tree for the binaries with the same structure
+(and using the same names) as the tree under the source directory. In
+the example, you'd find the Sun 4 library `libiberty.a' in the
+directory `gdb-sun4/libiberty', and GDB itself in `gdb-sun4/gdb'.
+
+ One popular use for building several GDB configurations in separate
+directories is to configure GDB for cross-compiling (where GDB runs on
+one machine--the host--while debugging programs that run on another
+machine--the target). You specify a cross-debugging target by giving
+the `--target=TARGET' option to `configure'.
+
+ When you run `make' to build a program or library, you must run it
+in a configured directory--whatever directory you were in when you
+called `configure' (or one of its subdirectories).
+
+ The `Makefile' generated by `configure' for each source directory
+also runs recursively. If you type `make' in a source directory such
+as `gdb-4.4' (or in a separate configured directory configured with
+`--srcdir=PATH/gdb-4.4'), you will build all the required libraries,
+then build GDB.
+
+ When you have multiple hosts or targets configured in separate
+directories, you can run `make' on them in parallel (for example, if
+they are NFS-mounted on each of the hosts); they will not interfere
+with each other.
+
+
+Specifying Names for Hosts and Targets
+======================================
+
+ The specifications used for hosts and targets in the `configure'
+script are based on a three-part naming scheme, but some short
+predefined aliases are also supported. The full naming scheme encodes
+three pieces of information in the following pattern:
-About the machine-dependent files...
+ ARCHITECTURE-VENDOR-OS
-m-<machine>.h (param.h is a link to this file).
-This file contains macro definitions that express information
-about the machine's registers, stack frame format and instructions.
+ For example, you can use the alias `sun4' as a HOST argument or in
+a `+target=TARGET' option, but the equivalent full name is
+`sparc-sun-sunos4'.
-<machine>-opcode.h (opcode.h is a link to this file).
-<machine>-pinsn.c (pinsn.c is a link to this file).
-These files contain the information necessary to print instructions
-for your cpu type.
+ The following table shows all the architectures, hosts, and OS
+prefixes that `configure' recognizes in GDB version 4.4. Entries in
+the "OS prefix" column ending in a `*' may be followed by a release
+number.
-<machine>-dep.c (dep.c is a link to this file).
-Those routines which provide a low level interface to ptrace and which
-tend to be machine-dependent. (The machine-independent routines are in
-`infrun.c' and `inflow.c')

+ *Warning:* `configure' can represent a very large number of
+ combinations of architecture, vendor, and OS. There is by no
+ means support available for all possible combinations!
+
+ The `configure' script accompanying GDB does not provide any query
+facility to list all supported host and target names or aliases.
+`configure' calls the Bourne shell script `config.sub' to map
+abbreviations to full names; you can read the script, if you wish, or
+you can use it to test your guesses on abbreviations--for example:
+
+ % sh config.sub sun4
+ sparc-sun-sunos4
+ % sh config.sub sun3
+ m68k-sun-sunos4
+ % sh config.sub decstation
+ mips-dec-ultrix
+ % sh config.sub hp300bsd
+ m68k-hp-bsd
+ % sh config.sub i386v
+ i386-none-sysv
+ % sh config.sub i486v
+ *** Configuration "i486v" not recognized
+
+`config.sub' is also distributed in the GDB source directory
+(`gdb-4.4', for version 4.4).
+
+
+`configure' Options
+===================
+
+ Here is a summary of all the `configure' options and arguments that
+you might use for building GDB:
+
+ configure [--destdir=DIR] [--srcdir=PATH]
+ [--norecursion] [--rm]
+ [--target=TARGET] HOST
+
+You may introduce options with a single `-' rather than `--' if you
+prefer; but you may abbreviate option names if you use `--'.
+
+`--destdir=DIR'
+ DIR is an installation directory *path prefix*. After you
+ configure with this option, `make install' will install GDB as
+ `DIR/bin/gdb', and the libraries in `DIR/lib'. If you specify
+ `--destdir=/usr/local', for example, `make install' creates
+ `/usr/local/bin/gdb'.
+
+`--srcdir=PATH'
+ Use this option to make configurations in directories separate
+ from the GDB source directories. Among other things, you can use
+ this to build (or maintain) several configurations
+ simultaneously, in separate directories. `configure' writes
+ configuration specific files in the current directory, but
+ arranges for them to use the source in the directory PATH.
+ `configure' will create directories under the working directory
+ in parallel to the source directories below PATH.
+
+`--norecursion'
+ Configure only the directory level where `configure' is executed;
+ do not propagate configuration to subdirectories.
+
+`--rm'
+ Remove the configuration that the other arguments specify.
+
+`--target=TARGET'
+ Configure GDB for cross-debugging programs running on the
+ specified TARGET. Without this option, GDB is configured to debug
+ programs that run on the same machine (HOST) as GDB itself.
+
+ There is no convenient way to generate a list of all available
+ targets.
+
+`HOST ...'
+ Configure GDB to run on the specified HOST.
+
+ There is no convenient way to generate a list of all available
+ hosts.
+
+`configure' accepts other options, for compatibility with configuring
+other GNU tools recursively; but these are the only options that
+affect GDB or its supporting libraries.
+
+
+ Languages other than C
+
+GDB provides some support for debugging C++ progams. Partial Modula-2
+support is now in GDB. GDB should work with FORTRAN programs. (If you
+have problems, please send a bug report; you may have to refer to some
+FORTRAN variables with a trailing underscore). I am not aware of
+anyone who is working on getting gdb to use the syntax of any other
+language. Pascal programs which use sets, subranges, file variables,
+or nested functions will not currently work.
+
+
+ Kernel debugging
+
+I have't done this myself so I can't really offer any advice.
+Remote debugging over serial lines works fine, but the kernel debugging
+code in here has not been tested in years. Van Jacobson claims to have
+better kernel debugging.
+
+
+ Remote debugging
+
+The files m68k-stub.c and i386-stub.c contain two examples of remote
+stubs to be used with remote.c. They are designeded to run standalone
+on a 68k or 386 cpu and communicate properly with the remote.c stub
+over a serial line.
+
+The file rem-multi.shar contains a general stub that can probably
+run on various different flavors of unix to allow debugging over a
+serial line from one machine to another.
+
+Some working remote interfaces for talking to existing ROM monitors
+are:
+ remote-eb.c AMD 29000 "EBMON"
+ remote-nindy.c Intel 960 "Nindy"
+ remote-adapt.c AMD 29000 "Adapt"
+ remote-mm.c AMD 29000 "minimon"
+
+Remote-vx.c and the vx-share subdirectory contain a remote interface for the
+VxWorks realtime kernel, which communicates over TCP using the Sun
+RPC library. This would be a useful starting point for other remote-
+via-ethernet back ends.
+
+
+ Reporting Bugs
+
+The correct address for reporting bugs found in gdb is
+Please include the GDB version number (e.g. gdb-4.4), and how
+you configured it (e.g. "sun4" or "mach386 host, i586-intel-synopsys
+target").
+
+A known bug:
+
+ * If you run with a watchpoint enabled, breakpoints will become
+ erratic and might not stop the program. Disabling or deleting the
+ watchpoint will fix the problem.
+
+GDB can produce warnings about symbols that it does not understand. By
+default, these warnings are disabled. You can enable them by executing
+`set complaint 10' (which you can put in your ~/.gdbinit if you like).
+I recommend doing this if you are working on a compiler, assembler,
+linker, or gdb, since it will point out problems that you may be able
+to fix. Warnings produced during symbol reading indicate some mismatch
+between the object file and GDB's symbol reading code. In many cases,
+it's a mismatch between the specs for the object file format, and what
+the compiler actually outputs or the debugger actually understands.
+
+If you port gdb to a new machine, please send the required changes to
+own port in the file gdb-4.4/gdb/doc/gdbint.texinfo, which you can
+print out, or read with `info' (see the Makefile.in there). If your
+changes are more than a few lines, obtain and send in a copyright
+`Writing Code for GDB'.
+
+
+ X Windows versus GDB
+
+xgdb is obsolete. We are not doing any development or support of it.
+
+There is an "xxgdb", which shows more promise, which was posted to
+comp.sources.x.
+
+For those intersted in auto display of source and the availability of
+an editor while debugging I suggest trying gdb-mode in gnu-emacs
+(Try typing M-x gdb RETURN). Comments on this mode are welcome.
+
+
+ Writing Code for GDB
We appreciate having users contribute code that is of general use, but
for it to be included in future GDB releases it must be cleanly
-written. We do not want to include changes that will needlessly make future
-maintainance difficult. It is not much harder to do things right, and
-in the long term it is worth it to the GNU project, and probably to
-you individually as well.
+written. We do not want to include changes that will needlessly make
+future maintainance difficult. It is not much harder to do things
+right, and in the long term it is worth it to the GNU project, and
+probably to you individually as well.
+
+If you make substantial changes, you'll have to file a copyright
+assignment with the Free Software Foundation before we can produce a
+release that includes your changes. Send mail requesting the copyright
+changes actually work, or even before you start them, because a manager
+or lawyer on your end will probably make this a slow process.
Please code according to the GNU coding standards. If you do not have
Please try to avoid making machine-specific changes to
-machine-independent files (i.e. all files except "param.h" and
-"dep.c". "pinsn.c" and "opcode.h" are processor-specific but not
-operating system-dependent). If this is unavoidable, put a hook in
-the machine-independent file which calls a (possibly)
-machine-dependent macro (for example, the IGNORE_SYMBOL macro can be
-used for any symbols which need to be ignored on a specific machine.
-Calling IGNORE_SYMBOL in dbxread.c is a lot cleaner than a maze of
-#if defined's). The machine-independent code should do whatever "most"
-machines want if the macro is not defined in param.h. Using #if defined
-can sometimes be OK (e.g. SET_STACK_LIMIT_HUGE) but should usually be
+machine-independent files. If this is unavoidable, put a hook in the

+macro (for example, the IGNORE_SYMBOL macro can be used for any
+symbols which need to be ignored on a specific machine. Calling
+IGNORE_SYMBOL in dbxread.c is a lot cleaner than a maze of #if
+defined's). The machine-independent code should do whatever "most"
+machines want if the macro is not defined in param.h. Using #if
+defined can sometimes be OK (e.g. SET_STACK_LIMIT_HUGE) but should be
conditionalized on a specific feature of an operating system (set in
-param.h) rather than something like #if defined(vax) or #if defined(SYSV).
+tm.h or xm.h) rather than something like #if defined(vax) or #if
+defined(SYSV). If you use an #ifdef on some symbol that is defined
+in a header file (e.g. #ifdef TIOCSETP), *please* make sure that you
+have #include'd the relevant header file in that module!
It is better to replace entire routines which may be system-specific,
rather than put in a whole bunch of hooks which are probably not going
to be helpful for any purpose other than your changes. For example,
if you want to modify dbxread.c to deal with DBX debugging symbols
-which are in COFF files rather than a.out files, do something
+which are in COFF files rather than BSD a.out files, do something
along the lines of a macro GET_NEXT_SYMBOL, which could have
different definitions for COFF and a.out, rather than trying to put
the necessary changes throughout all the code in dbxread.c that
-currently assumes a.out format.
+currently assumes BSD format.
-Please avoid duplicating code. For example, if something needs to be
-changed in read_inferior_memory, it is very painful because there is a
-copy in every dep.c file. The correct way to do this is to put the
-standard ptrace interfaces in a separate file ptrace.c, which is used
-by all systems which have ptrace. ptrace.c would deal with variations
-between systems the same way any system-independent file would (hooks,
-#if defined, etc.).
+When generalizing GDB along a particular interface, please use an
+attribute-struct rather than inserting tests or switch statements
+everywhere. For example, GDB has been generalized to handle multiple
+kinds of remote interfaces -- not by #ifdef's everywhere, but by
+defining the "target_ops" structure and having a current target (as
+well as a stack of targets below it, for memory references). Whenever
+something needs to be done that depends on which remote interface we
+are using, a flag in the current target_ops structure is tested (e.g.
+`target_has_stack'), or a function is called through a pointer in the
+current target_ops structure. In this way, when a new remote interface
+is added, only one module needs to be touched -- the one that actually
+implements the new remote interface. Other examples of
+attribute-structs are BFD access to multiple kinds of object file
+formats, or GDB's access to multiple source languages.
-About debugging gdb with itself...
+Please avoid duplicating code. For example, in GDB 3.x all the stuff
+in infptrace.c was duplicated in *-dep.c, and so changing something
+was very painful. In GDB 4.x, these have all been consolidated
+into infptrace.c. infptrace.c can deal with variations between
+systems the same way any system-independent file would (hooks, #if
+defined, etc.), and machines which are radically different don't need
+to use infptrace.c at all. The same was true of core_file_command
+and exec_file_command.
-You probably want to do a "make TAGS" after you configure your
-distribution; this will put the machine dependent routines for your
-local machine where they will be accessed first by a M-period .
-Also, you want to make sure that gdb is not compiled with shared
-libraries on the Sun 4. And you want to make sure that you've
-compiled gdb with your local cc or taken appropriate precautions
-regarding ansification of include files. See the Makefile for more
-information.
+ Debugging gdb with itself
-The "info" command, when executed without a subcommand in a gdb being
+If gdb is limping on your machine, this is the preferred way to get it
+fully functional. Be warned that in some ancient Unix systems, like
+Ultrix 4.0, a program can't be running in one process while it is being
+debugged in another. Rather than doing "./gdb ./gdb", which works on
+Suns and such, you can copy gdb to gdb2 and then do "./gdb ./gdb2".
+
+When you run gdb in the gdb source directory, it will read a ".gdbinit"
+file that sets up some simple things to make debugging gdb easier. The
+"info" command, when executed without a subcommand in a gdb being
debugged by gdb, will pop you back up to the top level gdb. See
-.gdbinit for more details.
+.gdbinit for details.
+
