incomplete/wrong debugging info #52

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
the following issues cause debugging info produced by gcc to be improperly
interpreted by dbx:

a) function-local symbols are not added to symtable
b) wrong section number of function arguments (and probably local symbols
as well, see (a)) in symtable: should be -1, gcc sets it to -2
c) wrong filename in the file symtable entry

(b) and (c) fixed with latest binutils 2.19 port (use optimized coff linker + 
add
language info to symtable entries) and gcc r140 (output file pseudo-op).

(a) is caused by bfd insisting on stripping local symbols. need to find out how 
to
change this behaviour.

actually, (a) is caused by gcc not outputting apropriate debug info into 
assembler in
the first place. need to debug sdbout.c ...
