line number info is not integrated correctly #3

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
right now, line no. entries are parsed and internally stored correctly.
however:

1. nm does not print symbol line numbers correctly,
2. objdump does not print line number info.

probably a problem with coff_find_[nearest_]line().

fixed a bfd bug with handling lineno entries. lineno entries for extern symbols 
work.
others don't.

lineno entry handling depends on aux entries being parsed (issue 4) correctly.

line numbers work
1. fine for defined .text symbols (functions, .bf, .ef)
2. need to test for defined .data symbols (produce data section lineno entries 
with sxcc)
3. does not work for undefined .text or .data symbols (i.e. referenced external 
vars
or funcs)

note: probably relocations need to be resolved before (3) can work at all.

relocations are not fully supported. need docs on relocations, though.
