* Makefile.am coff-pmac bfd now defined in coff-rs6000.c
|
||||
xcoff-target.h not used to define rs6000 or ppc bfd.
|
||||
* Makefile.in same
|
||||
|
||||
* bfd-in.h : (struct lineno_cache_entry) promote element "offset"
|
||||
to 64 bit.
|
||||
|
||||
* coff-rs6000.c : Many changes for 64 bit support. Move common
|
||||
32/64 code to xcofflink.c. Explictly define the rs6000coff_vec
|
||||
and pmac_xcoff_vec
|
||||
|
||||
* coff64-rs6000.c : Many changes for 64 bit support. 64 bit
|
||||
linker now supported. Explictly define the rs6000coff64_vec.
|
||||
|
||||
* coffcode.h : (coff_set_arch_mach_hook) xcoff 64 bit support
|
||||
(coff_print_aux) same
|
||||
(coff_write_object_contents) same
|
||||
(coff_slurp_line_table) same
|
||||
|
||||
* coffgen.c : (coff_fix_symbol_name) formatting
|
||||
(coff_mangle_symbols) xcoff 64 bit support
|
||||
(coff_write_symbol) same
|
||||
(coff_write_alien_symbol) same
|

(coff_write_native_symbol) same
|

(coff_write_symbols) same
|

(coff_get_symbol_info) same
|
||||
(bfd_coff_get_syment) same
|

(coff_print_symbol) same
|
||||
|
||||
* config.bfd : add powerpc64-*-aix* target
|
||||
|
||||
* libcoff-in.h : formatting
|
||||
|
||||
* libcoff.h : move xcoff extern declarations to libxcoff.h
|
||||
|
||||
* libxcoff.h : New file
|
||||
|
||||
* xcofflink.c : Many changes for xcoff64 support. Move common
|
||||
structures to include/coff/xcoff.h. Move specific structure to
|
||||
backends coff-rs6000.c and coff64-rs6000.c. Use new backend
|
||||
functions, defined in libxcoff.h, to isolate 32/64 dependencies.
|
||||
|
||||
(bfd_xcoff_size_dynamic_sections) : special __rtinit symbol for
|
||||
aix4.2+ -binitfini.
|
||||
|

(xcoff_build_ldsyms) : handle special __rtinit symbol.
