symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c:
Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)
Only worked if the first element in the list was
being deleted.
o When MAINLINE (reading main objectfile and need to
clear out old data), change elfread.c so that the
psymbol table is emptied once (in elf_symfile_read)
instead of multiple times in each *_read_psymtab
function.
o For elf_symfile_read, load dwarf2 symbols last
(so that they are searched for first).
o In mdebug_psymtab_read, delete check to see if
symbols for current source file already loaded.
Test doesn't work for .h files. Above change
works better

If we re-read something, call clear_symtab_users not just
breakpoint_re_set.
* objfiles.h, objfiles.c (build_objfile_section_table): No longer
static.
* symfile.c (clear_symtab_users): Call clear_pc_function_cache.
* coffread.c, dbxread.c, elfread.c, mipsread.c, nlmread.c, paread.c
(*_symfile_offsets): Set objfile->num_sections.
* remote.c (remote_wait), symfile.c (syms_from_objfile):
Don't muck with objfile->num_sections now that all the symbol
readers set it.
* elfread.c: Clean up obsolete comment about handling only DWARF.
* paread.c: Remove comment about how we should use an "ordinary"
file format with an hppa suffix. There is nothing ordinary about SOM.
initialized and uninitialized data sections have the SEC_ALLOC
flag bit set, but only initialized sections have SEC_LOAD set.
SEC_DATA is ignored since it only gets set for initialized
data. Likewise, SEC_HAS_CONTENTS is ignored now because it
never gets set.
use from the type.
* objfiles.c: Include gdb-stabs.h for SECT_* macros.
(objfile_relocate): Relocate textlow and texthigh in psymtabs.
Relocate partial symbols. Check that minimal SYMBOL_SECTION is
nonnegative before using it.
* symtab.h: Adjust section field comment.
