From Daniel Jacobowitz  <drow@mvista.com>
	* dbxread.c (dbx_symfile_read): Only reinitialize
	the psymbol list if mainline or if both static
	and global lists are empty.
	* dwarf2read.c (dwarf2_build_psymtabs): Likewise.
	* dwarfread.c (dwarf_build_psymtabs): Likewise.
	* xcoffread.c (xcoff_initial_scan): Likewise.

Jim Blandy 9e84cbde42 * dwarf2read.c (dwarf2_build_psymtabs_hard): Doc fix. 2001-07-30 23:16:45 +00:00
Jim Blandy af703f9620 * dwarf2read (dwarf2_build_psymtabs_hard): Doc fix. 2001-07-05 16:45:48 +00:00
Jim Blandy 0b010bcc00 * dwarf2read.c (struct partial_die_info): New member: has_pc_info.
(read_partial_die): Delete fourth argument; we return this info in
the struct partial_die_info object itself now.
(dwarf2_build_psymtabs_hard, scan_partial_symbols): Use the
has_pc_info field of the partial die struct, rather than passing a
variable by reference to read_partial_die.
2001-07-04 16:08:20 +00:00
Jim Blandy 2541c7cf08 * dwarf2read.c (dwarf2_build_psymtabs_hard): Remove extraneous
code in loop condition.  This seemed to be trying to round
info_ptr up to the next four-byte boundary, but that's not what it
actually did.  If we discover the problem the old code was really
trying to address, we can fix it properly.

        * breakpoint.c (breakpoint_here_p): Ditto.
        (breakpoint_inserted_here_p): Ditto.

        * gnu-regex.h: Define _REGEX_RE_COMP to pick up old compatability
        prototypes.

        * symtab.h: Add prototype for _initialize_source.
        * value.h: Add prototype for _initialize_value.

        * defs.h: Include sys/types.h or stddef.h to get size_t.
        (make_cleanup): Add make_cleanup_func typedef and switch to using
        a prototype for this function.
        (mfree): Add prototypes for mmalloc, mrealloc, mfree if we aren't

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. :-)
