PowerPC Improve support for Gekko & Broadway
This is a relatively straightforward patch to improve support for the
IBM Gekko and IBM Broadway processors. Broadway is functionally
equivalent to the IBM 750CL, while Gekko's functionality is a subset
of theirs. The patch simplifies this reality and adds -mgekko and
-mbroadway as aliases for -m750cl. I didn't feel it was worth wasting
a PPC_OPCODE_* bit to differentiate Gekko. The patch adds a number of
simplified mnemonics for special purpose register access. Notably,
Broadway adds 4 additional IBAT and DBAT registers but these are not
assigned sequential SPR numbers.
gas/
* config/tc-ppc.c (md_show_usage): Add -mgekko and -mbroadway.
* doc/as.texi (Target PowerPC options): Add -mgekko and -mbroadway.
* doc/c-ppc.texi (PowerPC-Opts): Likewise.
* testsuite/gas/ppc/broadway.d,
* testsuite/gas/ppc/broadway.s: New test for broadway.
* testsuite/gas/ppc/ppc.exp: Run new test.
include/
* opcode/ppc.h (PPC_OPCODE_750): Adjust comment.
opcodes/
* ppc-dis.c (ppc_opts): Add -mgekko and -mbroadway.
(powerpc_init_dialect): Handle bfd_mach_ppc_750.
* ppc-opc.c (insert_sprbat, extract_sprbat): New functions to
support disjointed BAT.
(powerpc_operands): Allow extra bit in SPRBAT_MASK. Add SPRGQR.
(XSPRGQR_MASK, GEKKO, BROADWAY): Define.
(powerpc_opcodes): Add 750cl extended mnemonics for spr access.
