SECTION_OFFSETS is a set of offsets to apply to relocate the symbols

in each section. This is ignored, as it isn't needed for SOM.
|

|

|
This function only does the minimum work necessary for letting the
|
|
|
|
|
user "name" things symbolically; it does not read the entire symtab.
|
|
|
|
|
Instead, it reads the external and static symbols and puts them in partial
|
|
|
|
|
symbol tables. When more extensive information is requested of a
|
|
|
|
|
file, the corresponding partial symbol table is mutated into a full
|
|
|
|
|
fledged symbol table by going back and reading the symbols
|
|
|
|
|
for real.
|

somstab_build_psymtabs() handles STABS symbols.
|

|
Note that SOM files have a "minimal" symbol table, which is vaguely
|
|
|
|
|
reminiscent of a COFF symbol table, but has only the minimal information
|
|
|
|
|
necessary for linking. We process this also, and use the information to
|
|
|
|
|
build gdb's minimal symbol table. This gives us some minimal debugging

|

capability even for files compiled without -g. */

* objfiles.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,
SECT_OFF_RODATA): Define as functions of OBJFILE. Add
sect_index_text, sect_index_data, sect_index_rodata,
sect_index_bss to objfile structure.
* gdb-stabs.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,
SECT_OFF_RODATA): Remove.
* objfiles.c (allocate_objfile): Initialize
sect_index_{text,data,bss,rodata} to -1, for error detection.
* symfile.c (default_symfile_offsets): Initialize
sect_index_{text,data,bss,rodata} from bfd information.
* xcoffread.c (xcoff_symfile_offsets): Ditto.
* somread.c (som_symfile_offsets): Initialize
sect_index_{text,data,bss,rodata}.
