Pass map->bin_file to bin_symbol_get_name.
2006-08-21 Soren Sandmann <sandmann@redhat.com> * process.c (process_lookup_symbol): Pass map->bin_file to bin_symbol_get_name. * binfile.h (bin_symbol_get_name): Add BinFile parameter * elfparser.c (elf_demangle): Use options DMGL_PARAMS | DMGL_ANSI * TODO: Updates * binfile.c: Rewrite this file to use ElfParser instead of libbfd. * configure.ac: Drop dependencies on libbfd and libiberty.

Before 1.2:
|
||||
|
||||
* See if we can make "In file <blah>" not be treated as a recursive function.
|
||||
|
||||
* Give more sensible 'error messages'. Ie., if you get permission denied for
|
||||
a file, put "Permission denied" instead of "No map"
|
||||
|
||||
* crc32 checking probably doesn't belong in elfparser.c
|
||||
|
||||
* Add demangling again
|
||||
|
||||
* Rethink binparser. Maybe the default mode should be:
|
||||
- there is a current offset
|
||||
- you can move the cursor
