|
||||
John Gilmore.
|
||||
|
||||
* a.out.gnu.h: Update slightly.
|
||||
* bfd.h: Add new error code, fix doc, add bfd_arch_rs6000.
|
||||
* internalcoff.h: Add more F_ codes for filehdr. Add
|
||||
rs/6000-dependent fields to aouthdr. Add storage classes
|
||||
to syments. Add 6000-specific auxent. Add r_size in reloc.
