|
a count of the number of sections. When bfd_map_over_sections
|
|
|
|
|
returns, this count is used to compute the pointer to the end of
|
|
|
|
|
the sections table, which then overwrites the count.
|
|
|
|
|
|
|
|
|
|
Also note that the OFFSET and OVLY_MAPPED in each table entry
|
|
|
|
|
are initialized to zero.
|
|
|
|
|
|
|

|

Also note that if anything else writes to the psymbol obstack while

|
|
|
we are building the table, we're pretty much hosed. */

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.
* acconfig.h (DEBUGDIR): New macro.
* configure, aclocal.m4, config.in: Regenerated.

for example, just to ensure that the mapped objfile doesn't appear twice

|
|
|
|
|
twice would create a circular list.

If OBJFILE turns out to be in the list, we zap it's NEXT pointer after

Support lexical blocks and function bodies that occupy
non-contiguous address ranges.
* addrmap.c, addrmap.h: New files.
* block.h (struct addrmap): New forward declaration.
(struct blockvector): New member, 'map'.
(BLOCKVECTOR_MAP): New accessor macro.
* block.c: #include "addrmap.h"
(blockvector_for_pc_sect): If the blockvector we've found has
an address map, use it instead of searching the blocks.

(pending_addrmap_obstack, pending_addrmap_interesting): New static
variables.
(really_free_pendings): If we have a pending addrmap, free it too.
(record_block_range): New function.
(make_blockvector): If we have an interesting pending addrmap,
record it in the new blockvector.
(start_symtab, buildsym_init): Assert that there is no pending
addrmap now; we should have cleaned up any addrmaps we'd built
previously.
(end_symtab): If there is a pending addrmap left over that didn't
get included in the blockvector, free it.
* buildsym.h (struct addrmap): New forward declaration.
(record_block_range): New prototype.

(addrmap.o): New rule.l
(block.o, objfiles.o, buildsym.o): Depend on $(addrmap_h).
* block.c (blockvector_for_pc, blockvector_for_pc_sect): Return a
pointer to the block, not its index in the blockvector.
(block_for_pc_sect): Use the returned block, instead of looking it
up ourselves.
* block.h (blockvector_for_pc, blockvector_for_pc_sect): Update
declarations.
* breakpoint.c (resolve_sal_pc): Use returned block, instead of
looking it up ourselves.
* stack.c (print_frame_label_vars): Disable function, which
depends on the block's index.
