|
||||
|
||||
* coff-ppc.c (ppc_record_toc_entry): new function.
|
||||
(in_reloc_p): changed return value.
|
||||
(coff_ppc_relocate_section): much rework.
|
||||
(ppc_allocate_toc_section): new function.
|
||||
(ppc_process_before_allocation): new function.
|
||||
(ppc_coff_swap_sym_in_hook): new function.
|
||||
|
||||
* cofflink.c (_bfd_coff_link_hash_newfunc): initialize toc_offset.
|
||||
(coff_link_add_symbols): initialize toc_offset.
|
||||
|
||||
* peicode.h (coff_swap_sym_in): Added coff_swap_sym_in_hook
|
||||
(coff_swap_aouthdr_out): Added more sections to the data
|
||||
dictionary for the pe file header. Also changed linker version
|
||||
number on the ppc side.
|
||||
(dir_names): small improvements to the dictionary printing.
|
||||
(pe_mkobject_hook): save the file level flags.
|
||||
|
||||
* libcoff-in.h (coff_link_hash_entry): added toc_offset field
|
||||
(pe_tdata): added real_flags field
|
||||
(coff_tdata): added local_toc_sym_map and access macro
|
||||
|
||||
* libcoff.h (coff_link_hash_entry): added toc_offset field
|
||||
(pe_tdata): added real_flags field
|
||||
(coff_tdata): added local_toc_sym_map and access macro
|
||||
|
||||
* coffcode.h (coff_set_alignment_hook): added hook for PE.
|
||||
(coff_mkobject): init for local_toc_sym_map
|
||||
(coff_write_object_contents): set the internal_a.magic to
|
||||
IMAGE_NT_OPTIONAL_HDR_MAGIC which appears to be what other
|
||||
ppc compilers use.
|
||||
