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. + (start_psymtab): Call elfstab_offset_sections to calculate good + 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 + argv processing. + * symtab.c (list_symbols): `i variables' shouldn't show enum values. + * xcoffexec.c: Clean up quote inside comment. + Fri Jul 3 20:18:26 1992 Fred Fish (fnf@cygnus.com) * breakpoint.c, buildsym.c, c-exp.y, coffread.c, command.c, |
