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. */
