From 72bba93b85e2e8c887df447c4237d0e7c21d07d8 Mon Sep 17 00:00:00 2001 From: Stu Grossman Date: Mon, 21 Mar 1994 19:57:38 +0000 Subject: Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com) * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to improve remote debugging efficiency. Also fixed problems with doing function calls for programs with no entry points. * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of entry_point_address. * inferior.h (PC_IN_CALL_DUMMY): ditto. * mdebugread.c (parse_symbol, parse_procedure, parse_external, parse_lines): Pass section_offsets info to these routines so that we can relocate symbol table entries upon readin. * (psymtab_to_symtab_1): Set symtab->primary to tell objfile_relocate to do relocations for our symbols. * (ecoff_relocate_efi): New routine to relocate adr field of PDRs (which hang off of the symbol table). * Use prim_record_minimal_symbols_and_info instead of prim_record_minimal_symbols to supply section info to make minimal symbol relocations work. * minsyms.c (prim_record_minimal_symbols_and_info): If section is -1, try to deduce it from ms_type. * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where appropriate. Handle relocation of MIPS_EFI symbols special. Also, add code to relocate objfile->sections data structure. * remote.c (get_offsets): Use new protocol message to acquire section offsets from the target. * (remote_wait): Get rid of relocation stuff. That's all handled by objfile_relocate now. * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h. * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and VM_MIN_ADDRESS. * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0. --- gdb/objfiles.c | 42 +++++++++++++++++++++++++++++++++++++++++- 1 file changed, 41 insertions(+), 1 deletion(-) (limited to 'gdb/objfiles.c') diff --git a/gdb/objfiles.c b/gdb/objfiles.c index 6c6dfc2..4f0dfd6 100644 --- a/gdb/objfiles.c +++ b/gdb/objfiles.c @@ -450,7 +450,7 @@ objfile_relocate (objfile, new_offsets) { struct symtab *s; - for (s = objfile->symtabs; s; s = s->next) + ALL_OBJFILE_SYMTABS (objfile, s) { struct linetable *l; struct blockvector *bv; @@ -492,6 +492,15 @@ objfile_relocate (objfile, new_offsets) SYMBOL_VALUE_ADDRESS (sym) += ANOFFSET (delta, SYMBOL_SECTION (sym)); } +#ifdef MIPS_EFI_SYMBOL_NAME + /* Relocate Extra Function Info for ecoff. */ + + else + if (SYMBOL_CLASS (sym) == LOC_CONST + && SYMBOL_NAMESPACE (sym) == LABEL_NAMESPACE + && STRCMP (SYMBOL_NAME (sym), MIPS_EFI_SYMBOL_NAME) == 0) + ecoff_relocate_efi (sym, ANOFFSET (delta, s->block_line_section)); +#endif } } } @@ -538,6 +547,37 @@ objfile_relocate (objfile, new_offsets) for (i = 0; i < objfile->num_sections; ++i) ANOFFSET (objfile->section_offsets, i) = ANOFFSET (new_offsets, i); } + + { + struct obj_section *s; + bfd *abfd; + + abfd = symfile_objfile->obfd; + + for (s = symfile_objfile->sections; + s < symfile_objfile->sections_end; ++s) + { + flagword flags; + + flags = bfd_get_section_flags (abfd, s->the_bfd_section); + + if (flags & SEC_CODE) + { + s->addr += ANOFFSET (delta, SECT_OFF_TEXT); + s->endaddr += ANOFFSET (delta, SECT_OFF_TEXT); + } + else if (flags & (SEC_DATA | SEC_LOAD)) + { + s->addr += ANOFFSET (delta, SECT_OFF_DATA); + s->endaddr += ANOFFSET (delta, SECT_OFF_DATA); + } + else if (flags & SEC_ALLOC) + { + s->addr += ANOFFSET (delta, SECT_OFF_BSS); + s->endaddr += ANOFFSET (delta, SECT_OFF_BSS); + } + } + } } /* Many places in gdb want to test just to see if we have any partial -- cgit v1.1
