|

|
||||
* configure.in: Add little endian PowerPC support.
|
||||
* configure: Rebuild with autoconf.
|
||||
* config/ppc-big.mt: New file for big endian PowerPC systems.
|
||||
* config/ppc-lit.mt: New file for little endian PowerPC systems.
|
||||
|
||||
* config/tc-ppc.h (target_big_endian): Declare.
|
||||
(TARGET_FORMAT): Deal with little and big endian ELF variants.
|
||||
(TARGET_BYTES_BIG_ENDIAN): Define as 1, not empty.
|
||||
|
||||
* config/tc-ppc.c (ppc_big_endian): Delete variable, use
|
||||
target_big_endian instead.
|
||||
(md_parse_option): Parse -mlittle and -mlittle-endian to use
|
||||
little endian support. Parse -mbig and -mbig-endian to use big
|
||||
endian support.
|
||||
(md_show_usage): Update to reflect current switches.
|
||||
(ppc_set_cpu): Recognize powerpcle as little endian PowerPC. Use
|
||||
as_fatal, not abort if unknown machine.
