@chapter Defining a New Host or Target Architecture
|
|
|
|
When building support for a new host and/or target, much of the work you
|
|
need to do is handled by specifying configuration files;
|
|
@pxref{Config,,Adding a New Configuration}. Further work can be
|
|
divided into ``host-dependent'' (@pxref{Host,,Adding a New Host}) and
|
|
``target-dependent'' (@pxref{Target,,Adding a New Target}). The
|
|
following discussion is meant to explain the difference between hosts
|
|
and targets.
|
|
|
|
@heading What is considered ``host-dependent'' versus ``target-dependent''?
|
|
|
|
@dfn{Host} refers to attributes of the system where GDB runs.
|
|
@dfn{Target} refers to the system where the program being debugged
|
|
executes. In most cases they are the same machine; unfortunately, that
|
|
means you must add @emph{both} host and target support for new machines
|
|
in this category.
|
|
|
|
The @file{config/mh-*}, @file{xm-*.h} and @file{*-xdep.c} files are for
|
|
host support. Similarly, the @file{config/mt-*}, @file{tm-*.h} and
|
|
@file{*-tdep.c} files are for target support. The question is, what
|
|
features or aspects of a debugging or cross-debugging environment are
|
|
considered to be ``host'' support?
|
|
|
|
Defines and include files needed to build on the host are host support.
|
|
Examples are tty support, system defined types, host byte order, host
|
|
float format.
|
|
|
|
Unix child process support is considered an aspect of the host. Since
|
|
when you fork on the host you are still on the host, the various macros
|
|
needed for finding the registers in the upage, running @code{ptrace}, and such
|
|
are all in the host-dependent files.
|
|
|
|
@c FIXME so what kinds of things are target support?
|
|
|
|
This is still somewhat of a grey area; I (John Gilmore) didn't do the
|
|
@file{xm-*} and @file{tm-*} split for gdb (it was done by Jim Kingdon)
|
|
so I have had to figure out the grounds on which it was split, and make
|
|
my own choices as I evolve it. I have moved many things out of the xdep
|
|
files actually, partly as a result of BFD and partly by removing
|
|
duplicated code.

@chapter Adding a New Configuration
|
|
|
|
Most of the work in making GDB compile on a new machine is in specifying
|
|
the configuration of the machine. This is done in a dizzying variety of
|
|
header files and configuration scripts, which we hope to make more
|
|
sensible soon. Let's say your new host is called an @var{xxx} (e.g.
|
|
@samp{sun4}), and its full three-part configuration name is
|
|
@code{@var{xarch}-@var{xvend}-@var{xos}} (e.g. @samp{sparc-sun-sunos4}). In
|
|
particular:
|
|
|
|
In the top level directory, edit @file{config.sub} and add @var{xarch},
|
|
@var{xvend}, and @var{xos} to the lists of supported architectures,
|
|
vendors, and operating systems near the bottom of the file. Also, add
|
|
@var{xxx} as an alias that maps to
|
|
@code{@var{xarch}-@var{xvend}-@var{xos}}. You can test your changes by
|
|
running
|
|
|
|
@example
|
|
./config.sub @var{xxx}
|
|
@end example
|
|
@noindent
|
|
and
|
|
@example
|
|
./config.sub @code{@var{xarch}-@var{xvend}-@var{xos}}
|
|
@end example
|
|
@noindent
|
|
which should both respond with @code{@var{xarch}-@var{xvend}-@var{xos}}
|
|
and no error messages.
|
|
|
|
Now, go to the @file{bfd} directory and
|
|
create a new file @file{bfd/hosts/h-@var{xxx}.h}. Examine the
|
|
other @file{h-*.h} files as templates, and create one that brings in the
|
|
right include files for your system, and defines any host-specific
|
|
macros needed by GDB.
|
|
|
|
Then edit @file{bfd/configure.in}. Add shell script code to recognize your
|
|
@code{@var{xarch}-@var{xvend}-@var{xos}} configuration, and set
|
|
@code{my_host} to @var{xxx} when you recognize it. This will cause your
|
|
file @file{h-@var{xxx}.h} to be linked to @file{sysdep.h} at configuration
|
|
time.
|
|
|
|
Also, if this host requires any changes to the Makefile, create a file
|
|
@file{bfd/config/mh-@var{xxx}}, which includes the required lines.
|
|
|
|
(If you have the binary utilities and/or GNU ld in the same tree,
|
|
you'll also have to edit @file{binutils/configure.in} or
|
|
@file{ld/configure.in} to match what you've done in the @file{bfd}
|
|
directory.)
|
|
|
|
It's possible that the @file{libiberty} and @file{readline} directories
|
|
won't need any changes for your configuration, but if they do, you can
|
|
change the @file{configure.in} file there to recognize your system and
|
|
map to an @file{mh-@var{xxx}} file. Then add @file{mh-@var{xxx}}
|
|
to the @file{config/} subdirectory, to set any makefile variables you
|
|
need. The only current options in there are things like @samp{-DSYSV}.
|
|
|
|
Aha! Now to configure GDB itself! Edit
|
|
@file{gdb/configure.in} to recognize your system and set @code{gdb_host}
|
|
to @var{xxx}, and (unless your desired target is already available) also
|
|
set @code{gdb_target} to something appropriate (for instance,
|
|
@var{xxx}). To handle new hosts, modify the segment after the comment
|
|
@samp{# per-host}; to handle new targets, modify after @samp{#
|
|
per-target}.
|
|
@c Would it be simpler to just use different per-host and per-target
|
|
@c *scripts*, and call them from {configure} ?
|
|
|
|
Finally, you'll need to specify and define GDB's host- and
|
|
target-dependent @file{.h} and @file{.c} files used for your
|
|
configuration; the next two chapters discuss those.
|
|

@chapter Adding a New Host
|
|
|
|
Once you have specified a new configuration for your host
|
|
(@pxref{Config,,Adding a New Configuration}), there are two remaining
|
|
pieces to making GDB work on a new machine. First, you have to make it
|
|
host on the new machine (compile there, handle that machine's terminals
|
|
properly, etc). If you will be cross-debugging to some other kind of
|
|
system that's already supported, you are done.
|
|
|
|
If you want to use GDB to debug programs that run on the new machine,
|
|
you have to get it to understand the machine's object files, symbol
|
|
files, and interfaces to processes. @pxref{Target,,Adding a New Target}
|
|
|
|
Several files control GDB's configuration for host systems:
|
|
|
|
@table @file
|
|
@item gdb/config/mh-@var{xxx}
|
|
Specifies Makefile fragments needed when hosting on machine @var{xxx}.
|
|
In particular, this lists the required machine-dependent object files,
|
|
by defining @samp{XDEPFILES=@dots{}}. Also
|
|
specifies the header file which describes host @var{xxx}, by defining
|
|
@samp{XM_FILE= xm-@var{xxx}.h}. You can also define @samp{CC},
|
|
@samp{REGEX} and @samp{REGEX1}, @samp{SYSV_DEFINE}, @samp{XM_CFLAGS},
|
|
@samp{XM_ADD_FILES}, @samp{XM_CLIBS}, @samp{XM_CDEPS},
|
|
etc.; see @file{Makefile.in}.
|
|
|
|
@item gdb/xm-@var{xxx}.h
|
|
(@file{xm.h} is a link to this file, created by configure).
|
|
Contains C macro definitions describing the host system environment,
|
|
such as byte order, host C compiler and library, ptrace support,
|
|
and core file structure. Crib from existing @file{xm-*.h} files
|
|
to create a new one.
|
|
|
|
@item gdb/@var{xxx}-xdep.c
|
|
Contains any miscellaneous C code required for this machine
|
|
as a host. On some machines it doesn't exist at all.
|
|
@end table
|
|
|
|
There are some ``generic'' versions of routines that can be used by
|
|
various host systems. These can be customized in various ways by macros
|
|
defined in your @file{xm-@var{xxx}.h} file. If these routines work for
|
|
the @var{xxx} host, you can just include the generic file's name (with
|
|
@samp{.o}, not @samp{.c}) in @code{XDEPFILES}.
|
|
|
|
Otherwise, if your machine needs custom support routines, you will need
|
|
to write routines that perform the same functions as the generic file.
|
|
Put them into @code{@var{xxx}-xdep.c}, and put @code{@var{xxx}-xdep.o}
|
|
into @code{XDEPFILES}.
|
|
|
|
@subheading Generic Host Support Files
|
|
|
|
@table @file
|
|
|
|
@item infptrace.c
|
|
This is the low level interface to inferior processes for systems
|
|
using the Unix @code{ptrace} call in a vanilla way.
|
|
|
|
@item coredep.c::fetch_core_registers()
|
|
Support for reading registers out of a core file. This routine calls
|
|
@code{register_addr()}, see below.
|
|
Now that BFD is used to read core files, virtually all machines should
|
|
use @code{coredep.c}, and should just provide @code{fetch_core_registers} in
|
|
@code{@var{xxx}-xdep.c} (or @code{REGISTER_U_ADDR} in @code{xm-@var{xxx}.h}).
|
|
|
|
@item coredep.c::register_addr()
|
|
If your @code{xm-@var{xxx}.h} file defines the macro
|
|
@code{REGISTER_U_ADDR(addr, blockend, regno)}, it should be defined to
|
|
set @code{addr} to the offset within the @samp{user}
|
|
struct of GDB register number @code{regno}. @code{blockend} is the
|
|
offset within the ``upage'' of @code{u.u_ar0}.
|
|
If @code{REGISTER_U_ADDR} is defined,
|
|
@file{coredep.c} will define the @code{register_addr()} function and use
|
|
the macro in it. If you do not define @code{REGISTER_U_ADDR}, but you
|
|
are using the standard @code{fetch_core_registers()}, you will need to
|
|
define your own version of @code{register_addr()}, put it into your
|
|
@code{@var{xxx}-xdep.c} file, and be sure @code{@var{xxx}-xdep.o} is in
|
|
the @code{XDEPFILES} list. If you have your own
|
|
@code{fetch_core_registers()}, you may not need a separate
|
|
@code{register_addr()}. Many custom @code{fetch_core_registers()}
|
|
implementations simply locate the registers themselves.@refill
|
|
@end table
|
|
|
|
Object files needed when the target system is an @var{xxx} are listed
|
|
in the file @file{config/mt-@var{xxx}}, in the makefile macro
|
|
@samp{TDEPFILES = }@dots{}. The header file that defines the target
|
|
system should be called @file{tm-@var{xxx}.h}, and should be specified
|
|
as the value of @samp{TM_FILE} in @file{config/mt-@var{xxx}}. You can
|
|
also define @samp{TM_CFLAGS}, @samp{TM_CLIBS}, and @samp{TM_CDEPS} in
|
|
there; see @file{Makefile.in}.
|
|
|
|
Now, you are now ready to try configuring GDB to compile for your system.
|
|
From the top level (above @file{bfd}, @file{gdb}, etc), do:
|
|
|
|
@example
|
|
./configure @var{xxx} +target=vxworks960
|
|
@end example
|
|
|
|
This will configure your system to cross-compile for VxWorks on
|
|
the Intel 960, which is probably not what you really want, but it's
|
|
a test case that works at this stage. (You haven't set up to be
|
|
able to debug programs that run @emph{on} @var{xxx} yet.)
|
|
|
|
If this succeeds, you can try building it all with:
|
|
|
|
@example
|
|
make
|
|
@end example
|
|
|
|
Good luck! Comments and suggestions about this section are particularly
|
|
welcome; send them to @samp{bug-gdb@@prep.ai.mit.edu}.
|
|
|
|
When hosting GDB on a new operating system, to make it possible to debug
|
|
core files, you will need to either write specific code for parsing your
|
|
OS's core files, or customize @file{bfd/trad-core.c}. First, use
|
|
whatever @code{#include} files your machine uses to define the struct of
|
|
registers that is accessible (possibly in the u-area) in a core file
|
|
(rather than @file{machine/reg.h}), and an include file that defines whatever
|
|
header exists on a core file (e.g. the u-area or a @samp{struct core}). Then
|
|
modify @code{trad_unix_core_file_p()} to use these values to set up the
|
|
section information for the data segment, stack segment, any other
|
|
segments in the core file (perhaps shared library contents or control
|
|
information), ``registers'' segment, and if there are two discontiguous
|
|
sets of registers (e.g. integer and float), the ``reg2'' segment. This
|
|
section information basically delimits areas in the core file in a
|
|
standard way, which the section-reading routines in BFD know how to seek
|
|
around in.
|
|
|
|
Then back in GDB, you need a matching routine called
|
|
@code{fetch_core_registers()}. If you can use the generic one, it's in
|
|
@file{core-dep.c}; if not, it's in your @file{@var{xxx}-xdep.c} file.
|
|
It will be passed a char pointer to the entire ``registers'' segment,
|
|
its length, and a zero; or a char pointer to the entire ``regs2''
|
|
segment, its length, and a 2. The routine should suck out the supplied
|
|
register values and install them into GDB's ``registers'' array.

@chapter Adding a New Target
|
|
|
|
For a new target called @var{ttt}, first specify the configuration as
|
|
described in @ref{Config,,Adding a New Configuration}. If your new
|
|
target is the same as your new host, you've probably already done that.
|
|
|
|
A variety of files specify attributes of the GDB target environment:
|
|
|
|
@table @file
|
|
@item gdb/config/mt-@var{ttt}
|
|
Contains a Makefile fragment specific to this target.
|
|
Specifies what object files are needed for target @var{ttt}, by
|
|
defining @samp{TDEPFILES=@dots{}}.
|
|
Also specifies the header file which describes @var{ttt}, by defining
|
|
@samp{TM_FILE= tm-@var{ttt}.h}. You can also define @samp{TM_CFLAGS},
|
|
and other Makefile variables here; see @file{Makefile.in}.
|
|
|
|
@item gdb/tm-@var{ttt}.h
|
|
(@file{tm.h} is a link to this file, created by configure).
|
|
Contains macro definitions about the target machine's
|
|
registers, stack frame format and instructions.
|
|
Crib from existing @file{tm-*.h} files when building a new one.
|
|
|
|
@item gdb/@var{ttt}-tdep.c
|
|
Contains any miscellaneous code required for this target machine.
|
|
On some machines it doesn't exist at all. Sometimes the macros
|
|
in @file{tm-@var{ttt}.h} become very complicated, so they are
|
|
implemented as functions here instead, and the macro is simply
|
|
defined to call the function.
|
|
|
|
@item gdb/exec.c
|
|
Defines functions for accessing files that are
|
|
executable on the target system. These functions open and examine an
|
|
exec file, extract data from one, write data to one, print information
|
|
about one, etc. Now that executable files are handled with BFD, every
|
|
target should be able to use the generic exec.c rather than its
|
|
own custom code.
|
|
|
|
@item gdb/@var{arch}-pinsn.c
|
|
Prints (disassembles) the target machine's instructions.
|
|
This file is usually shared with other target machines which use the
|
|
same processor, which is why it is @file{@var{arch}-pinsn.c} rather
|
|
than @file{@var{ttt}-pinsn.c}.
|
|
|
|
@item gdb/@var{arch}-opcode.h
|
|
Contains some large initialized
|
|
data structures describing the target machine's instructions.
|
|
This is a bit strange for a @file{.h} file, but it's OK since
|
|
it is only included in one place. @file{@var{arch}-opcode.h} is shared
|
|
between the debugger and the assembler, if the GNU assembler has been
|
|
ported to the target machine.
|
|
|
|
@item gdb/tm-@var{arch}.h
|
|
This often exists to describe the basic layout of the target machine's
|
|
processor chip (registers, stack, etc).
|
|
If used, it is included by @file{tm-@var{xxx}.h}. It can
|
|
be shared among many targets that use the same processor.
|
|
|
|
@item gdb/@var{arch}-tdep.c
|
|
Similarly, there are often common subroutines that are shared by all
|
|
target machines that use this particular architecture.
|
|
@end table
|
|
|
|
When adding support for a new target machine, there are various areas
|
|
of support that might need change, or might be OK.
|
|
|
|
If you are using an existing object file format (a.out or COFF),
|
|
there is probably little to be done. See @file{bfd/doc/bfd.texinfo}
|
|
for more information on writing new a.out or COFF versions.
|
|
|
|
If you need to add a new object file format, you are beyond the scope
|
|
of this document right now. Look at the structure of the a.out
|
|
and COFF support, build a transfer vector (@code{xvec}) for your new format,
|
|
and start populating it with routines. Add it to the list in
|
|
@file{bfd/targets.c}.
|
|
|
|
If you are adding a new operating system for an existing CPU chip, add a
|
|
@file{tm-@var{xos}.h} file that describes the operating system
|
|
facilities that are unusual (extra symbol table info; the breakpoint
|
|
instruction needed; etc). Then write a
|
|
@file{tm-@var{xarch}-@var{xos}.h} that just @code{#include}s
|
|
@file{tm-@var{xarch}.h} and @file{tm-@var{xos}.h}. (Now that we have
|
|
three-part configuration names, this will probably get revised to
|
|
separate the @var{xos} configuration from the @var{xarch}
|
|
configuration.)

parsed expressions into a @samp{union exp_element} list are in @file{parse.c}.
|
|
|
|
Since we can't depend upon everyone having Bison, and YACC produces
|
|
parsers that define a bunch of global names, the following lines
|
|
@emph{must} be included at the top of the YACC parser, to prevent
|
|
the various parsers from defining the same global names:
|
|
|
|
@example
|
|
#define yyparse @var{lang}_parse
|
|
#define yylex @var{lang}_lex
|
|
#define yyerror @var{lang}_error
|
|
#define yylval @var{lang}_lval
|
|
#define yychar @var{lang}_char
|
|
#define yydebug @var{lang}_debug
|
|
#define yypact @var{lang}_pact
|
|
#define yyr1 @var{lang}_r1
|
|
#define yyr2 @var{lang}_r2
|
|
#define yydef @var{lang}_def
|
|
#define yychk @var{lang}_chk
|
|
#define yypgo @var{lang}_pgo
|
|
#define yyact @var{lang}_act
|
|
#define yyexca @var{lang}_exca
|
|
#define yyerrflag @var{lang}_errflag
|
|
#define yynerrs @var{lang}_nerrs
|
|
@end example
|
|
|
|
At the bottom of your parser, define a @code{struct language_defn} and
|
|
initialize it with the right values for your language. Define an
|
|
@code{initialize_@var{lang}} routine and have it call
|
|
@samp{add_language(@var{lang}_language_defn)} to tell the rest of GDB
|
|
that your language exists. You'll need some other supporting variables
|
|
and functions, which will be used via pointers from your
|
|
@code{@var{lang}_language_defn}. See the declaration of @code{struct
|
|
language_defn} in @file{language.h}, and the other @file{*-exp.y} files,
|
|
for more information.
|
|
|
|
@item Add any evaluation routines, if necessary
|
|
|
|
If you need new opcodes (that represent the operations of the language),
|
|
add them to the enumerated type in @file{expression.h}. Add support
|
|
code for these operations in @code{eval.c:evaluate_subexp()}. Add cases
|
|
for new opcodes in two functions from @file{parse.c}:
|
|
@code{prefixify_subexp()} and @code{length_of_subexp()}. These compute
|
|
the number of @code{exp_element}s that a given operation takes up.
|
|
|
|
@item Update some existing code
|
|
|
|
Add an enumerated identifier for your language to the enumerated type
|
|
@code{enum language} in @file{defs.h}.
|
|
|
|
Update the routines in @file{language.c} so your language is included. These
|
|
routines include type predicates and such, which (in some cases) are
|
|
language dependent. If your language does not appear in the switch
|
|
statement, an error is reported.
|
|
|
|
Also included in @file{language.c} is the code that updates the variable
|
|
@code{current_language}, and the routines that translate the
|
|
@code{language_@var{lang}} enumerated identifier into a printable
|
|
string.
|
|
|
|
Update the function @code{_initialize_language} to include your language. This
|
|
function picks the default language upon startup, so is dependent upon
|
|
which languages that GDB is built for.
|
|
|
|
Update @code{allocate_symtab} in @file{symfile.c} and/or symbol-reading
|
|
code so that the language of each symtab (source file) is set properly.
|
|
This is used to determine the language to use at each stack frame level.
|
|
Currently, the language is set based upon the extension of the source
|
|
file. If the language can be better inferred from the symbol
|
|
information, please set the language of the symtab in the symbol-reading
|
|
code.
|
|
|
|
Add helper code to @code{expprint.c:print_subexp()} to handle any new
|
|
expression opcodes you have added to @file{expression.h}. Also, add the
|
|
printed representations of your operators to @code{op_print_tab}.
|
|
|
|
@item Add a place of call
|
|
|
|
Add a call to @code{@var{lang}_parse()} and @code{@var{lang}_error} in
|
|
@code{parse.c:parse_exp_1()}.
|
|
|
|
@item Use macros to trim code
|
|
|
|
The user has the option of building GDB for some or all of the
|
|
languages. If the user decides to build GDB for the language
|
|
@var{lang}, then every file dependent on @file{language.h} will have the
|
|
macro @code{_LANG_@var{lang}} defined in it. Use @code{#ifdef}s to
|
|
leave out large routines that the user won't need if he or she is not
|
|
using your language.
|
|
|
|
Note that you do not need to do this in your YACC parser, since if GDB
|
|
is not build for @var{lang}, then @file{@var{lang}-exp.tab.o} (the
|
|
compiled form of your parser) is not linked into GDB at all.
|
|
|
|
See the file @file{configure.in} for how GDB is configured for different
|
|
languages.
|
|
|
|
@item Edit @file{Makefile.in}
|
|
|
|
Add dependencies in @file{Makefile.in}. Make sure you update the macro
|
|
variables such as @code{HFILES} and @code{OBJS}, otherwise your code may
|
|
not get linked in, or, worse yet, it may not get @code{tar}red into the
|
|
distribution!

@chapter Partial Symbol Tables
|
|
|
|
GDB has three types of symbol tables.
|
|
|
|
@itemize @bullet
|
|
@item full symbol tables (symtabs). These contain the main
|
|
information about symbols and addresses.
|
|
@item partial symbol tables (psymtabs). These contain enough
|
|
information to know when to read the corresponding
|
|
part of the full symbol table.
|
|
@item minimal symbol tables (msymtabs). These contain information
|
|
gleaned from non-debugging symbols.
|
|
@end itemize
|
|
|
|
This section describes partial symbol tables.
|
|
|
|
A psymtab is constructed by doing a very quick pass over an executable
|
|
file's debugging information. Small amounts of information are
|
|
extracted -- enough to identify which parts of the symbol table will
|
|
need to be re-read and fully digested later, when the user needs the
|
|
information. The speed of this pass causes GDB to start up very
|
|
quickly. Later, as the detailed rereading occurs, it occurs in small
|
|
pieces, at various times, and the delay therefrom is mostly invisible to
|
|
the user. (@xref{Symbol Reading}.)
|
|
|
|
The symbols that show up in a file's psymtab should be, roughly, those
|
|
visible to the debugger's user when the program is not running code from
|
|
that file. These include external symbols and types, static
|
|
symbols and types, and enum values declared at file scope.
|
|
|
|
The psymtab also contains the range of instruction addresses that the
|
|
full symbol table would represent.
|
|
|
|
The idea is that there are only two ways for the user (or much of
|
|
the code in the debugger) to reference a symbol:
|
|
|
|
@itemize @bullet
|
|
|
|
@item by its address
|
|
(e.g. execution stops at some address which is inside a function
|
|
in this file). The address will be noticed to be in the
|
|
range of this psymtab, and the full symtab will be read in.
|
|
@code{find_pc_function}, @code{find_pc_line}, and other @code{find_pc_@dots{}}
|
|
functions handle this.
|
|
|
|
@item by its name
|
|
(e.g. the user asks to print a variable, or set a breakpoint on a
|
|
function). Global names and file-scope names will be found in the
|
|
psymtab, which will cause the symtab to be pulled in. Local names will
|
|
have to be qualified by a global name, or a file-scope name, in which
|
|
case we will have already read in the symtab as we evaluated the
|
|
qualifier. Or, a local symbol can be referenced when
|
|
we are "in" a local scope, in which case the first case applies.
|
|
@code{lookup_symbol} does most of the work here.
|
|
|
|
@end itemize
|
|
|
|
The only reason that psymtabs exist is to cause a symtab to be read in
|
|
at the right moment. Any symbol that can be elided from a psymtab,
|
|
while still causing that to happen, should not appear in it. Since
|
|
psymtabs don't have the idea of scope, you can't put local symbols in
|
|
them anyway. Psymtabs don't have the idea of the type of a symbol,
|
|
either, so types need not appear, unless they will be referenced by
|
|
name.
|
|
|
|
It is a bug for GDB to behave one way when only a psymtab has been read,
|
|
and another way if the corresponding symtab has been read in. Such
|
|
bugs are typically caused by a psymtab that does not contain all the
|
|
visible symbols, or which has the wrong instruction address ranges.
|
|
|
|
The psymtab for a particular section of a symbol-file (objfile)
|
|
could be thrown away after the symtab has been read in. The symtab
|
|
should always be searched before the psymtab, so the psymtab will
|
|
never be used (in a bug-free environment). Currently,
|
|
psymtabs are allocated on an obstack, and all the psymbols themselves
|
|
are allocated in a pair of large arrays on an obstack, so there is
|
|
little to be gained by trying to free them unless you want to do a lot
|
|
more work.

@node BFD support for GDB, Symbol Reading, Partial Symbol Tables, Top
|
|
@chapter Binary File Descriptor Library Support for GDB
|
|
|
|
BFD provides support for GDB in several ways:
|
|
|
|
@table @emph
|
|
@item identifying executable and core files
|
|
BFD will identify a variety of file types, including a.out, coff, and
|
|
several variants thereof, as well as several kinds of core files.
|
|
|
|
@item access to sections of files
|
|
BFD parses the file headers to determine the names, virtual addresses,
|
|
sizes, and file locations of all the various named sections in files
|
|
(such as the text section or the data section). GDB simply calls
|
|
BFD to read or write section X at byte offset Y for length Z.
|
|
|
|
@item specialized core file support
|
|
BFD provides routines to determine the failing command name stored
|
|
in a core file, the signal with which the program failed, and whether
|
|
a core file matches (i.e. could be a core dump of) a particular executable
|
|
file.
|
|
|
|
@item locating the symbol information
|
|
GDB uses an internal interface of BFD to determine where to find the
|
|
symbol information in an executable file or symbol-file. GDB itself
|
|
handles the reading of symbols, since BFD does not ``understand'' debug
|
|
symbols, but GDB uses BFD's cached information to find the symbols,
|
|
string table, etc.
|
|
@end table
|
|
|
|
@c The interface for symbol reading is described in @ref{Symbol
|
|
@c Reading,,Symbol Reading}.

@node Symbol Reading, Cleanups, BFD support for GDB, Top
|
|
@chapter Symbol Reading
|
|
|
|
GDB reads symbols from "symbol files". The usual symbol file is the
|
|
file containing the program which gdb is debugging. GDB can be directed
|
|
to use a different file for symbols (with the ``symbol-file''
|
|
command), and it can also read more symbols via the ``add-file'' and ``load''
|
|
commands, or while reading symbols from shared libraries.
|
|
|
|
Symbol files are initially opened by @file{symfile.c} using the BFD
|
|
library. BFD identifies the type of the file by examining its header.
|
|
@code{symfile_init} then uses this identification to locate a
|
|
set of symbol-reading functions.
|
|
|
|
Symbol reading modules identify themselves to GDB by calling
|
|
@code{add_symtab_fns} during their module initialization. The argument
|
|
to @code{add_symtab_fns} is a @code{struct sym_fns} which contains
|
|
the name (or name prefix) of the symbol format, the length of the prefix,
|
|
and pointers to four functions. These functions are called at various
|
|
times to process symbol-files whose identification matches the specified
|
|
prefix.
|
|
|
|
The functions supplied by each module are:
|
|
|
|
@table @code
|
|
@item @var{xxx}_symfile_init(struct sym_fns *sf)
|
|
|
|
Called from @code{symbol_file_add} when we are about to read a new
|
|
symbol file. This function should clean up any internal state
|
|
(possibly resulting from half-read previous files, for example)
|
|
and prepare to read a new symbol file. Note that the symbol file
|
|
which we are reading might be a new "main" symbol file, or might
|
|
be a secondary symbol file whose symbols are being added to the
|
|
existing symbol table.
|
|
|
|
The argument to @code{@var{xxx}_symfile_init} is a newly allocated
|
|
@code{struct sym_fns} whose @code{bfd} field contains the BFD
|
|
for the new symbol file being read. Its @code{private} field
|
|
has been zeroed, and can be modified as desired. Typically,
|
|
a struct of private information will be @code{malloc}'d, and
|
|
a pointer to it will be placed in the @code{private} field.
|
|
|
|
There is no result from @code{@var{xxx}_symfile_init}, but it can call
|
|
@code{error} if it detects an unavoidable problem.
|
|
|
|
@item @var{xxx}_new_init()
|
|
|
|
Called from @code{symbol_file_add} when discarding existing symbols.
|
|
This function need only handle
|
|
the symbol-reading module's internal state; the symbol table data
|
|
structures visible to the rest of GDB will be discarded by
|
|
@code{symbol_file_add}. It has no arguments and no result.
|
|
It may be called after @code{@var{xxx}_symfile_init}, if a new symbol
|
|
table is being read, or may be called alone if all symbols are
|
|
simply being discarded.
|
|
|
|
@item @var{xxx}_symfile_read(struct sym_fns *sf, CORE_ADDR addr, int mainline)
|
|
|
|
Called from @code{symbol_file_add} to actually read the symbols from a
|
|
symbol-file into a set of psymtabs or symtabs.
|
|
|
|
@code{sf} points to the struct sym_fns originally passed to
|
|
@code{@var{xxx}_sym_init} for possible initialization. @code{addr} is the
|
|
offset between the file's specified start address and its true address
|
|
in memory. @code{mainline} is 1 if this is the main symbol table being
|
|
read, and 0 if a secondary symbol file (e.g. shared library or
|
|
dynamically loaded file) is being read.@refill
|
|
@end table
|
|
|
|
In addition, if a symbol-reading module creates psymtabs when
|
|
@var{xxx}_symfile_read is called, these psymtabs will contain a pointer to
|
|
a function @code{@var{xxx}_psymtab_to_symtab}, which can be called from
|
|
any point in the GDB symbol-handling code.
|
|
|
|
@table @code
|
|
@item @var{xxx}_psymtab_to_symtab (struct partial_symtab *pst)
|
|
|
|
Called from @code{psymtab_to_symtab} (or the PSYMTAB_TO_SYMTAB
|
|
macro) if the psymtab has not already been read in and had its
|
|
@code{pst->symtab} pointer set. The argument is the psymtab
|
|
to be fleshed-out into a symtab. Upon return, pst->readin
|
|
should have been set to 1, and pst->symtab should contain a
|
|
pointer to the new corresponding symtab, or zero if there
|
|
were no symbols in that part of the symbol file.

@chapter Cleanups
|
|
|
|
Cleanups are a structured way to deal with things that need to be done
|
|
later. When your code does something (like @code{malloc} some memory, or open
|
|
a file) that needs to be undone later (e.g. free the memory or close
|
|
the file), it can make a cleanup. The cleanup will be done at some
|
|
future point: when the command is finished, when an error occurs, or
|
|
when your code decides it's time to do cleanups.
|
|
|
|
You can also discard cleanups, that is, throw them away without doing
|
|
what they say. This is only done if you ask that it be done.
|
|
|
|
Syntax:
|
|
|
|
@table @code
|
|
@item @var{old_chain} = make_cleanup (@var{function}, @var{arg});
|
|
Make a cleanup which will cause @var{function} to be called with @var{arg}
|
|
(a @code{char *}) later. The result, @var{old_chain}, is a handle that can be
|
|
passed to @code{do_cleanups} or @code{discard_cleanups} later. Unless you are
|
|
going to call @code{do_cleanups} or @code{discard_cleanups} yourself,
|
|
you can ignore the result from @code{make_cleanup}.
|
|
|
|
|
|
@item do_cleanups (@var{old_chain});
|
|
Perform all cleanups done since @code{make_cleanup} returned @var{old_chain}.
|
|
E.g.:
|
|
@example
|
|
make_cleanup (a, 0);
|
|
old = make_cleanup (b, 0);
|
|
do_cleanups (old);
|
|
@end example
|
|
@noindent
|
|
will call @code{b()} but will not call @code{a()}. The cleanup that calls @code{a()} will remain
|
|
in the cleanup chain, and will be done later unless otherwise discarded.@refill
|
|
|
|
@item discard_cleanups (@var{old_chain});
|
|
Same as @code{do_cleanups} except that it just removes the cleanups from the
|
|
chain and does not call the specified functions.
|
|
|
|
@end table
|
|
|
|
Some functions, e.g. @code{fputs_filtered()} or @code{error()}, specify that they
|
|
``should not be called when cleanups are not in place''. This means
|
|
that any actions you need to reverse in the case of an error or
|
|
interruption must be on the cleanup chain before you call these functions,
|
|
since they might never return to your code (they @samp{longjmp} instead).
|
|
|
|
|
|
@node Wrapping, Frames, Cleanups, Top
|
|
@chapter Wrapping Output Lines
|
|
|
|
Output that goes through @code{printf_filtered} or @code{fputs_filtered} or
|
|
@code{fputs_demangled} needs only to have calls to @code{wrap_here} added
|
|
in places that would be good breaking points. The utility routines
|
|
will take care of actually wrapping if the line width is exceeded.
|
|
|
|
The argument to @code{wrap_here} is an indentation string which is printed
|
|
@emph{only} if the line breaks there. This argument is saved away and used
|
|
later. It must remain valid until the next call to @code{wrap_here} or
|
|
until a newline has been printed through the @code{*_filtered} functions.
|
|
Don't pass in a local variable and then return!
|
|
|
|
It is usually best to call @code{wrap_here()} after printing a comma or space.
|
|
If you call it before printing a space, make sure that your indentation
|
|
properly accounts for the leading space that will print if the line wraps
|
|
there.
|
|
|
|
Any function or set of functions that produce filtered output must finish
|
|
by printing a newline, to flush the wrap buffer, before switching to
|
|
unfiltered (``@code{printf}'') output. Symbol reading routines that print
|
|
warnings are a good example.

@chapter Frames
|
|
|
|
A frame is a construct that GDB uses to keep track of calling and called
|
|
functions.
|
|
|
|
@table @code
|
|
@item FRAME_FP
|
|
in the machine description has no meaning to the machine-independent
|
|
part of GDB, except that it is used when setting up a new frame from
|
|
scratch, as follows:
|
|
|
|
@example
|
|
create_new_frame (read_register (FP_REGNUM), read_pc ()));
|
|
@end example
|
|
|
|
Other than that, all the meaning imparted to @code{FP_REGNUM} is imparted by
|
|
the machine-dependent code. So, @code{FP_REGNUM} can have any value that
|
|
is convenient for the code that creates new frames. (@code{create_new_frame}
|
|
calls @code{INIT_EXTRA_FRAME_INFO} if it is defined; that is where you should
|
|
use the @code{FP_REGNUM} value, if your frames are nonstandard.)
|
|
|
|
@item FRAME_CHAIN
|
|
Given a GDB frame, determine the address of the calling function's
|
|
frame. This will be used to create a new GDB frame struct, and then
|
|
@code{INIT_EXTRA_FRAME_INFO} and @code{INIT_FRAME_PC} will be called for
|
|
the new frame.

@item U_REGS_OFFSET
|

This is the offset of the registers in the upage. It need only be defined
|
|
if the generic ptrace register access routines in @file{infptrace.c}
|
|
are being used
|
|
(that is, @code{FETCH_INFERIOR_REGISTERS} is not defined). If the default
|
|
value from @file{infptrace.c} is good enough, leave it undefined.
|
|
|
|
The default value means that u.u_ar0 @emph{points to} the location of the
|
|
registers. I'm guessing that @code{#define U_REGS_OFFSET 0} means that
|
|
u.u_ar0 @emph{is} the location of the registers.

When GDB is configured and compiled, various macros are defined or left

undefined, to control compilation based on the attributes of the target

system. These macros and their meanings are:

|
|
|
@emph{NOTE: For now, both host and target conditionals are here.

Eliminate host conditionals from this list as they are identified.}
