1998-10-11 * dwarf2read.c (dwarf2_build_psymtabs_hard): Do not adjust thePeter Schauer1-3/+4
address range of a compilation unit without children. * mdebugread.c (parse_partial_symbols): Fix handling of stabs continuations, use xmalloc and xrealloc.
1998-07-02 * mdebugread.c (parse_partial_symbols): Go ahead and read the .mdebugDawn Perchik1-94/+92
section, but just don't add a 2nd minimal symbol if this is an .mdebug section in an ELF file.
1998-04-22Humoring RMS by saying "GNU/Linux" instead of just "Linux"Stan Shebs1-1/+1
1998-04-07 * mdebugread.c (parse_partial_symbols): If this is an .mdebugDawn Perchik1-110/+202
section in an ELF file, override a symbol's ECOFF section with its ELF section. Also, fix stabs continuation where a stabs string continues for more than one continuation.
1997-12-17o Fix code deleting psymtab entry from objfile's list.Andrew Cagney1-7/+0
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
1997-10-22 * mdebugread.c (psymtab_to_symtab_1): Handle new live range stabsJeff Law1-1/+8
entries. * dbxread.c: More comment cleanups. * stabsread.c: Fix various violations of the GNU coding and formatting standards. Update/add comments to make code clearer. (resolve_reference): Delete unused function. (ref_search_val): Remove function. It didn't belong in stabsread.c (resolve_live_range): No longer returns a value. Do not add it to the live range list until the entire range stab has been parsed. (get_substring): Remove duplicate declaration. (resolve_symbol_reference): Now static. Remove unnecessary code to deal with cleanups. (ref_add): Use xrealloc instea of realloc. (process_reference): Reorganize slightly to make clearer. * stabsread.h (resolve_symbol_reference): Remove declaration. (resolve_reference): Likewise. * symtab.c (find_active_alias): New function. (lookup_block_symbol): Use find_active_alias. * symtab.h (struct range_list): Fix dangling struct live_range reference. (ref_search_val): Remove decl. * symtab.h (struct range_list): Renamed from struct live_range. (struct symbol): Remove struct live_range_info substruct. Bring the alias list and range list fields up to the toplevel as "aliases" and "ranges". (SYMBOL_ALIASES, SYMBOL_RANGES): Corresponding changes. (SYMBOL_RANGE_START, SYMBOL_RANGE_END, SYMBOL_RANGE_NEXT): Delete. * stabsread.c: Corresponding changes. Bring first round of cleanups over from r5900 branch.

Initialize temporary obstack for symbol reading, initialize buildsym and add a cleanup to really_free_pendings. Relocate highpc with baseaddr when calling end_symtab.

(dwarf_attr): Return NULL if reference die for DW_AT_specification or DW_AT_abstract_origin die is not found. (record_minimal_symbol): Removed, replaced with a direct call to prim_record_minimal_symbol, it now handles saving the string itself.

Thu Jul 25 19:41:31 1996 Fred Fish <fnf@cygnus.com> for a rather huge set of changes. I was going to put them here, but it made cvs dump core. :-(
1996-07-23 * Makefile.in (os9kread.o): Remove dependency on partial-stab.h.Stu Grossman1-3/+3
* dbxread.c (read_dbx_symtab end_psymtab), partial-stab.h: Don't use partial_symtab->textlow==0 as a flag, as 0 is a legitimate text address. Use a seperate flag (textlow_not_set) instead. This makes stabs in ELF .o files work a lot better. * mdebugread.c xcoffread.c: Define textlow_not_set for partial-stab.h. * stabsread.h (end_psymtab): Add textlow_not_set arg to prototype.
1996-07-08(laying some groundwork for a fix for PR 8443)Fred Fish1-2/+5
* coffread.c (record_minimal_symbol): Don't presave name string on symbol_obstack before passing to prim_record_minimal_symbol.

1996-05-26 Changes from: David Mosberger-Tang <davidm@azstarnet.com>Fred Fish1-1/+17
* NEWS: Add Alpha Linux as a new native configuration. * mdebugread.c (parse_symbol): When we find a malloc() symbol with return type VOID, assume no debugging info is available for that object file and patch the return value into VOID *. Otherwise, operations requiring an implicit call to malloc() will fail. * infrun.c (wait_for_inferior): The criterion to detect entering a sigtramp handler is now: (a) the current pc is inside a sigtramp handler, (b) the previous pc is not in a sigtramp handler, and (c) the current stack pointer is "inner" than the old one. Condition (c) is new to avoid mistaking a return from a signal handler into sigtramp as a new sigtramp invocation. * dcache.c (struct dcache_block): Declare addr as CORE_ADDR. An int may not be big enough to hold an address. (dcache_hit): Ditto. (dcache_peek_byte): Fix indentation. * configure.in (alpha-*-linux*): Add target. * configure: Rebuild * config/alpha/tm-alpha.h (PROC_DESC_IS_DYN_SIGTRAMP): New macro. (SET_PROC_DESC_IS_DYN_SIGTRAMP): Ditto. (DYNAMIC_SIGTRAMP_OFFSET): Ditto. (SIGCONTEXT_ADDR): Ditto. (FRAME_PAST_SIGTRAMP_FRAME): Ditto. * config/alpha/alpha-linux.mh: New file. * config/alpha/alpha-linux.mt: Ditto. * config/alpha/nm-linux.h: Ditto. * config/alpha/tm-alphalinux.h: Ditto. * config/alpha/xm-alphalinux.h: Ditto. * config/alpha/xm-alphaosf.h: Renamed from xm-alpha.h. * config/alpha/alpha-osf1.mh (XM_FILE): Change from xm-alpha.h to xm-alphaosf.h. * config/alpha/alpha-osf2.mh: Ditto. * blockframe.c (find_pc_partial_function): Pass PC to SIGTRAMP_START and SIGTRAMP_END macros for the benefit of systems that detect sigtramp code via designated code sequences (as is the case for Linux/Alpha, for example). * config/i386/tm-i386bsd.h: Change SIGTRAMP_START and SIGTRAMP_END to ignore new PC argument. * config/m68k/tm-hp300bsd.h: Ditto. * config/vax/tm-vax.h: Ditto. * alpha-tdep.c (alpha_linux_sigtramp_offset): New function. (alpha_osf_skip_sigtramp_frame): Ditto. (push_sigtramp_desc): Ditto. (alpha_find_saved_regs): Use SIGCONTEXT_ADDR macro to extract sigcontext address from frame. (alpha_saved_pc_after_call): When in sigtramp, use alpha_frame_saved_pc() instead of read-register(). (after_prologue): When inside a dynamically generated sigtramp function, there is no prologue, so return address of first instruction. (alpha_in_prologue): Fix typo in comment. (find_proc_desc): Use macro DYNAMIC_SIGTRAMP_OFFSET to determine whether we're inside a dynamicaly generated sigtramp function. If so, create and push and appropriate procedure descriptor. (alpha_frame_chain): Use macro FRAME_PAST_SIGTRAMP_FRAME to obtain the frame past a sigtramp frame (if the current frame is indeed a sigtramp function). (init_extra_frame_info): Don't read next frame register off of stack-pointer when inside a dynamiccaly generated sigtramp.
