(fill_symbuf): Support an in-memory buffer for stabs data. (stabs_seek): New function. (dbx_psymtab_to_symtab): Relocate the stabs data if necessary. (read_ofile_symtab): Use stabs_seek. (elfstab_build_psymtabs): Take an asection* instead of an offset and size. Relocate the stabs data if necessary. Save the section* for dbx_psymtab_to_symtab. * dwarf2read.c: Add section variables for each debug section. (dwarf2_locate_sections): Fill them in. (dwarf2_read_section): Take an asection* argument. Relocate the section contents if necessary. (dwarf2_build_psymtabs, dwarf2_build_psymtabs_easy): Update callers. * dwarf2cfi.c (parse_frame_info): Take a section argument and pass it to dwarf2_read_section. (dwarf2_build_frame_info): Update callers. * elfread.c (elf_symfile_read): Update call to elfstab_build_psymtabs. * gdb-stabs.h (struct dbx_symfile_info): Add stab_section. (DBX_STAB_SECTION): New macro. * stabsread.h (elfstab_build_psymtabs): Update prototype. * symfile.c (symfile_dummy_outputs): New function. (symfile_relocate_debug_section): New function. * symfile.h (symfile_relocate_debug_section): Add prototype.
