+ * dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.".
+ * procfs.c (proc_set_exec_trap): Set run-on-last-close flag on
+ child processes, to avoid dead ones "hanging around" after GDB exits.
+ (attach): Always stop the process if it needs it. Set RLC flag
+ when attaching running processes, so it will continue if we detach
+ it, quit, or are killed.
+ (detach): Clear faults and set RLC flag to make process run
+ when we close it.
+ (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR.
+ Callers changed.
+ (info_proc): Open process O_RDONLY, so we can see any process,

+
+Sat Jul 4 03:43:38 1992 John Gilmore (gnu at cygnus.com)
+
+ Relocate symbols using an array of section_offsets, rather than a
+ single `addr' or `offset'. This makes Solaris-2 support work, and
+ permits better VxWorks (and maybe xcoff) support later.
+
+ * symtab.h (struct section_offsets): New structure for keeping
+ a set of offsets, rather than a single one.
+ (struct objfile): Replace addr with section_offsets member.
+ * symfile.h: Add sym_offsets to struct sym_fns. Conforming changes.
+ * gdb-stabs.h: New include file with `symbol type specific'
+ parameters for psymtabs and objfiles.
+ * Makefile.in (HFILES): Add gdb-stabs.h.
+ * buildsym.h (start_psymtab, process_one_symbol): Fix prototypes.
+ * coffread.c: Conforming changes. Fake offset array always 0.
+ * dbxread.c: Conforming changes.
+ (struct dbx_symfile_info): Move to gdb-stabs.h.

+ offsets for this source file, based on the ELF symbol table info.
+ (read_ofile_symtab): Yank N_CATCH, which is dead.
+ (process_one_symbol, N_CATCH): Yank.
+ (", N_FUN, N_FNAME, N_FN, N_FN_SEQ, N_SO, N_SOL, N_ENTRY):
+ Relocate with SECT_OFF_TEXT.
+ (", N_STSYM, N_LCSYM, N_ROSYM): Grope around in the stab string
+ to distinguish relocatable from absolute symbols. Then, if not
+ absolute, do:
+ (", N_STSYM, N_DSLINE): SECT_OFF_DATA.
+ (", N_LCSYM, N_BSLINE): SECT_OFF_BSS.
+ (", N_ROSYM): SECT_OFF_RODATA.
+ (elfstab_build_psymtabs): Caller has allocated dbx_symfile_info.
+ (dbx_symfile_offsets): Add to translate addr to offset.
+ * dwarfread.c: Conforming changes. Single offset currently used.
+ * elfread.c: Add various complaints about elf/stab stuff.
+ #include gdb-stabs.h. Conforming changes, using a single offset.
+ (elf_symtab_read): Record info from BSF_FILE symbols, and local
+ variables called "Bbss.bss", "Ddata.data", and "Drodata.rodata",
+ for later use in building psymtabs.
+ (elf_symfile_read): Allocate dbx_symfile_info here, to keep
+ the info collected in elf_symtab_read. Cleanup calls free_elfinfo.
+ (free_elfinfo): New fn, frees all chained stab_section_infos
+ in an objfile, and zaps the start-of-chain pointer.
+ (elfstab_offset_sections): New fn, looks in stab_section_info
+ chain to determine section bases to relocate a psymtab's worth
+ of symbols, as they are being read.
+ * mipsread.c: Conforming changes. Stabs-reading will relocate
+ using one offset. MIPS-reading will not relocate at all.
+ * partial-stab.h: Relocate different symbol types using different
+ offsets from section_offsets.
+ * symfile.c: Conforming changes.
+ (find_lowest_section): Unused function to use later
+ to free us from the Tyranny of the Text Section.
+ (syms_from_objfile): Translate absolute arg ADDR to offsets used
+ in all lower layers of symbol reading. Call format-specific
+ sym_offsets function to initialize offsets for high speed symbol
+ reading.
+ (symbol_file_add): Call reinit_frame_cache so callers don't have to.
+ (symbol_file_command, add_symbol_file_command): Callers changed.
+ * symmisc.c (dump_psymtab): Print new relocation parameters.
+ * xcoffread.c: Corresponding changes.
+
+ * buildsym.c: Tidy innerblock_complaint and blockvector_complaint.
+ * main.c (main): Read the $HOME/.gdbinit file before processing
+ the argv arguments (e.g. reading symbol files or core
+ files). This allows global parameters to be set, which will apply
+ during the symbol reading. The ./.gdbinit is still read after

+ * partial-stab.h: Ignore N_ENDM.
+ * elfread.c (elf_symtab_read): Ignore symbols that don't have a
+ CODE or DATA section attachment. This eliminates a lot of random
+ values from shared libraries, which screw up the ordinary symbols
+ in the address ranges they happen to overlap.
+ * buildsym.c (define_symbol): Eliminate special tests
+ for function types; move into "function" cases in switch statement.
+ (define_symbol: 'f', 'F', 'P'): Process all parameter types

+ * defs.h (alloca): More diddling with alloca. Have to ensure

+
+
+ * sparc-pinsn.c: Use <string.h> rather than "string.h", for
