1999-05-12 Alan Modra <alan@apri.levels.unisa.edu.au>
* i386.h (ReverseModrm): Remove all occurences.
(InvMem): Add to control/debug/test mov insns, movhlps, movlhps,
movmskps, pextrw, pmovmskb, maskmovq.
Change NoSuf to FP on all MMX, XMM and AMD insns as these all
ignore the data size prefix.
* i386.h (i386_optab, i386_regtab): Add support for PIII SIMD.
Mostly stolen from Doug Ledford <dledford@redhat.com>
Sat May 8 23:27:35 1999 Richard Henderson <rth@cygnus.com>
* ppc.h (PPC_OPCODE_64_BRIDGE): New.
