From 9ed8433a04bf0430e2da3cd44c18667859782410 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 10 Apr 2023 10:50:09 -0600 Subject: Rename objfile::sections I think objfile::sections makes sense as the name of the method to iterate over an objfile's sections, so this patch renames the existing field to objfile::sections_start in preparation for that. --- gdb/machoread.c | 2 +- gdb/maint.c | 6 +++--- gdb/objfiles.c | 12 ++++++------ gdb/objfiles.h | 20 ++++++++++---------- gdb/solib-aix.c | 4 ++-- gdb/solib-dsbt.c | 2 +- gdb/solib-frv.c | 2 +- gdb/symfile.c | 2 +- gdb/symmisc.c | 2 +- gdb/symtab.c | 4 ++-- gdb/xcoffread.c | 3 ++- 11 files changed, 30 insertions(+), 29 deletions(-) diff --git a/gdb/machoread.c b/gdb/machoread.c index 9735de80d57..dc841c30af2 100644 --- a/gdb/machoread.c +++ b/gdb/machoread.c @@ -926,7 +926,7 @@ macho_symfile_offsets (struct objfile *objfile, ALL_OBJFILE_OSECTIONS (objfile, osect) { const char *bfd_sect_name = osect->the_bfd_section->name; - int sect_index = osect - objfile->sections;; + int sect_index = osect - objfile->sections_start; if (startswith (bfd_sect_name, "LC_SEGMENT.")) bfd_sect_name += 11; diff --git a/gdb/maint.c b/gdb/maint.c index a8afef0e16b..3cd2c5e899a 100644 --- a/gdb/maint.c +++ b/gdb/maint.c @@ -331,11 +331,11 @@ maint_obj_section_from_bfd_section (bfd *abfd, asection *asection, objfile *ofile) { - if (ofile->sections == nullptr) + if (ofile->sections_start == nullptr) return nullptr; obj_section *osect - = &ofile->sections[gdb_bfd_section_index (abfd, asection)]; + = &ofile->sections_start[gdb_bfd_section_index (abfd, asection)]; if (osect >= ofile->sections_end) return nullptr; @@ -375,7 +375,7 @@ maint_print_all_sections (const char *header, bfd *abfd, objfile *objfile, if (objfile != nullptr) { - gdb_assert (objfile->sections != nullptr); + gdb_assert (objfile->sections_start != nullptr); osect = maint_obj_section_from_bfd_section (abfd, sect, objfile); if (osect->the_bfd_section == nullptr) diff --git a/gdb/objfiles.c b/gdb/objfiles.c index 9caebfefd59..e3fa691dd53 100644 --- a/gdb/objfiles.c +++ b/gdb/objfiles.c @@ -264,7 +264,7 @@ add_to_objfile_sections (struct bfd *abfd, struct bfd_section *asect, return; } - section = &objfile->sections[gdb_bfd_section_index (abfd, asect)]; + section = &objfile->sections_start[gdb_bfd_section_index (abfd, asect)]; section->objfile = objfile; section->the_bfd_section = asect; section->ovly_mapped = 0; @@ -280,10 +280,10 @@ build_objfile_section_table (struct objfile *objfile) { int count = gdb_bfd_count_sections (objfile->obfd.get ()); - objfile->sections = OBSTACK_CALLOC (&objfile->objfile_obstack, - count, - struct obj_section); - objfile->sections_end = (objfile->sections + count); + objfile->sections_start = OBSTACK_CALLOC (&objfile->objfile_obstack, + count, + struct obj_section); + objfile->sections_end = (objfile->sections_start + count); for (asection *sect : gdb_bfd_sections (objfile->obfd)) add_to_objfile_sections (objfile->obfd.get (), sect, objfile, 0); @@ -660,7 +660,7 @@ objfile_relocate1 (struct objfile *objfile, struct obj_section *s; ALL_OBJFILE_OSECTIONS (objfile, s) { - int idx = s - objfile->sections; + int idx = s - objfile->sections_start; exec_set_section_address (bfd_get_filename (objfile->obfd.get ()), idx, s->addr ()); diff --git a/gdb/objfiles.h b/gdb/objfiles.h index 342aa09ac6a..1b059dddf5d 100644 --- a/gdb/objfiles.h +++ b/gdb/objfiles.h @@ -128,7 +128,7 @@ struct entry_info }; #define ALL_OBJFILE_OSECTIONS(objfile, osect) \ - for (osect = objfile->sections; osect < objfile->sections_end; osect++) \ + for (osect = objfile->sections_start; osect < objfile->sections_end; osect++) \ if (osect->the_bfd_section == NULL) \ { \ /* Nothing. */ \ @@ -713,16 +713,16 @@ public: int sect_index_bss = -1; int sect_index_rodata = -1; - /* These pointers are used to locate the section table, which - among other things, is used to map pc addresses into sections. - SECTIONS points to the first entry in the table, and - SECTIONS_END points to the first location past the last entry - in the table.
