/* This structure maintains information on a per-objfile basis about the
|
|
|
|
|
"entry point" of the objfile, and the scope within which the entry point
|
|
|
|
|
exists. It is possible that gdb will see more than one objfile that is
|
|
|
|
|
executable, each with its own entry point.
|
|
|
|
|
|
|
|
|
|
For example, for dynamically linked executables in SVR4, the dynamic linker
|
|
|
|
|
code is contained within the shared C library, which is actually executable
|
|
|
|
|
and is run by the kernel first when an exec is done of a user executable
|
|
|
|
|
that is dynamically linked. The dynamic linker within the shared C library
|
|
|
|
|
then maps in the various program segments in the user executable and jumps
|
|
|
|
|
to the user executable's recorded entry point, as if the call had been made
|
|
|
|
|
directly by the kernel.
|
|
|
|
|
|
2004-05-07 16:29:34 +02:00
|
|
|
|
The traditional gdb method of using this info was to use the
|
|
|
|
|
recorded entry point to set the entry-file's lowpc and highpc from
|
2003-09-12 20:40:18 +02:00
|
|
|
|
the debugging information, where these values are the starting
|
|
|
|
|
address (inclusive) and ending address (exclusive) of the
|
|
|
|
|
instruction space in the executable which correspond to the
|
2011-01-10 21:38:51 +01:00
|
|
|
|
"startup file", i.e. crt0.o in most cases. This file is assumed to
|
2003-09-12 20:40:18 +02:00
|
|
|
|
be a startup file and frames with pc's inside it are treated as
|
|
|
|
|
nonexistent. Setting these variables is necessary so that
|
|
|
|
|
backtraces do not fly off the bottom of the stack.
|
|
|
|
|
|
|
|
|
|
NOTE: cagney/2003-09-09: It turns out that this "traditional"
|
|
|
|
|
method doesn't work. Corinna writes: ``It turns out that the call
|
2004-04-30 22:44:59 +02:00
|
|
|
|
to test for "inside entry file" destroys a meaningful backtrace
|
2011-01-10 21:38:51 +01:00
|
|
|
|
under some conditions. E.g. the backtrace tests in the asm-source
|
2003-09-12 20:40:18 +02:00
|
|
|
|
testcase are broken for some targets. In this test the functions
|
|
|
|
|
are all implemented as part of one file and the testcase is not
|
|
|
|
|
necessarily linked with a start file (depending on the target).
|
|
|
|
|
What happens is, that the first frame is printed normaly and
|
|
|
|
|
following frames are treated as being inside the enttry file then.
|
|
|
|
|
This way, only the #0 frame is printed in the backtrace output.''

Gdb also supports an alternate method to avoid running off the bottom
|
|
|
|
|
of the stack.
|
|
|
|
|
|
|
|
|
|
There are two frames that are "special", the frame for the function
|
|
|
|
|
containing the process entry point, since it has no predecessor frame,
|
|
|
|
|
and the frame for the function containing the user code entry point
|
|
|
|
|
(the main() function), since all the predecessor frames are for the
|
|
|
|
|
process startup code. Since we have no guarantee that the linked
|
|
|
|
|
in startup modules have any debugging information that gdb can use,
|
|
|
|
|
we need to avoid following frame pointers back into frames that might
|
|
|
|
|
have been built in the startup code, as we might get hopelessly
|
|
|
|
|
confused. However, we almost always have debugging information
|
|
|
|
|
available for main().
|
|
|
|
|
|
2003-03-24 04:54:51 +01:00
|
|
|
|
These variables are used to save the range of PC values which are
|
|
|
|
|
valid within the main() function and within the function containing
|
|
|
|
|
the process entry point. If we always consider the frame for
|
|
|
|
|
main() as the outermost frame when debugging user code, and the
|
|
|
|
|
frame for the process entry point function as the outermost frame
|
|
|
|
|
when debugging startup code, then all we have to do is have
|
|
|
|
|
DEPRECATED_FRAME_CHAIN_VALID return false whenever a frame's
|
|
|
|
|
current PC is within the range specified by these variables. In
|
|
|
|
|
essence, we set "ceilings" in the frame chain beyond which we will
|
1999-04-16 03:35:26 +02:00
|
|
|
|
not proceed when following the frame chain back up the stack.
|
|
|
|
|
|
|
|
|
|
A nice side effect is that we can still debug startup code without
|
|
|
|
|
running off the end of the frame chain, assuming that we have usable
|
|
|
|
|
debugging information in the startup modules, and if we choose to not
|
|
|
|
|
use the block at main, or can't find it for some reason, everything
|
|
|
|
|
still works as before. And if we have no startup code debugging
|
|
|
|
|
information but we do have usable information for main(), backtraces
|
2004-02-04 17:34:51 +01:00
|
|
|
|
from user code don't go wandering off into the startup code. */

2003-01-23 Alexander Larsson <alexl@redhat.com>
Jim Blandy <jimb@redhat.com>
Add support for executables whose debug info has been separated
out into a separate file, leaving only a link behind.
* objfiles.h (struct objfile): New fields: separate_debug_objfile
and separate_debug_objfile_backlink.
(put_objfile_before): New declaration.
* symfile.c: #include "filenames.h".
(symbol_file_add_with_addrs_or_offsets): If this objfile has its
debug info in a separate file, read that, too. Save the addrs
argument, so we can use it again to read the separated debug info;
syms_from_objfile modifies the table we pass it.
(reread_symbols): After re-reading an objfile, call
reread_separate_symbols to refresh its separate debug info
objfile, if it has one.
(reread_separate_symbols, find_separate_debug_file,
get_debug_link_info, separate_debug_file_exists): New functions.
(debug_file_directory): New global var.
(_initialize_symfile): Initialize debug_file_directory, and
provide the new `set debug-file-directory' command to let the user
change it.
* objfiles.c (free_objfile): If this objfile has its debug info in
a separate objfile, free that one too. If this is itself a
separate debug info objfile, clear our parent's backlink.
(put_objfile_before): New function.
* utils.c (gnu_debuglink_crc32): New function.
* defs.h (gnu_debuglink_crc32): New declaration.
* Makefile.in (symfile.o): Note dependency on "filenames.h".
* configure.in: Handle --with-separate-debug-dir config option.
* acinclude.m4 (AC_DEFINE_DIR): New macro.

(put_objfile_before): New declaration.
* symfile.c: #include "filenames.h".
(symbol_file_add_with_addrs_or_offsets): If this objfile has its
debug info in a separate file, read that, too. Save the addrs
argument, so we can use it again to read the separated debug info;
syms_from_objfile modifies the table we pass it.

reread_separate_symbols to refresh its separate debug info
objfile, if it has one.

get_debug_link_info, separate_debug_file_exists): New functions.
(debug_file_directory): New global var.
(_initialize_symfile): Initialize debug_file_directory, and
provide the new `set debug-file-directory' command to let the user
change it.
* objfiles.c (free_objfile): If this objfile has its debug info in
a separate objfile, free that one too. If this is itself a
separate debug info objfile, clear our parent's backlink.

Note that this detects a "break" in the inner loop, and exits
|
|
|
|
|
immediately from the outer loop as well, thus, client code doesn't
|
|
|
|
|
need to know that this is implemented with a double for. The extra
|
|
|
|
|
hair is to make sure that a "break;" stops the outer loop iterating
|
|
|
|
|
as well, and both OBJFILE and OSECT are left unmodified:
|
|
|
|
|
|
|
|
|
|
- The outer loop learns about the inner loop's end condition, and
|
|
|
|
|
stops iterating if it detects the inner loop didn't reach its
|
|
|
|
|
end. In other words, the outer loop keeps going only if the
|
|
|
|
|
inner loop reached its end cleanly [(osect) ==
|
|
|
|
|
(objfile)->sections_end].
|
|
|
|
|
|
|
|
|
|
- OSECT is initialized in the outer loop initialization
|
|
|
|
|
expressions, such as if the inner loop has reached its end, so
|
|
|
|
|
the check mentioned above succeeds the first time.
|
|
|
|
|
|
|
|
|
|
- The trick to not clearing OBJFILE on a "break;" is, in the outer
|
|
|
|
|
loop's loop expression, advance OBJFILE, but iff the inner loop
|
|
|
|
|
reached its end. If not, there was a "break;", so leave OBJFILE
|
|
|
|
|
as is; the outer loop's conditional will break immediately as
|
2011-01-10 21:38:51 +01:00
|
|
|
|
well (as OSECT will be different from OBJFILE->sections_end). */

SECT_OFF_RODATA): Define as functions of OBJFILE. Add
sect_index_text, sect_index_data, sect_index_rodata,
sect_index_bss to objfile structure.
* gdb-stabs.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,
SECT_OFF_RODATA): Remove.
* objfiles.c (allocate_objfile): Initialize
sect_index_{text,data,bss,rodata} to -1, for error detection.
* symfile.c (default_symfile_offsets): Initialize
sect_index_{text,data,bss,rodata} from bfd information.
* xcoffread.c (xcoff_symfile_offsets): Ditto.
