From 7a5c0744901c6370bd339c1af9d8caf337bf4acf Mon Sep 17 00:00:00 2001 From: Peter Bergner Date: Thu, 2 Apr 2009 13:30:56 +0000 Subject: opcodes/ * ppc-dis.c (powerpc_init_dialect): Do not choose a default dialect due to -many/-Many. (print_insn_powerpc): Make sure we only deprecate instructions using the original dialect and not a modified dialect due to -Many handling. Move the handling of the condition register and default operands to the end of the if/else if/else chain. * ppc-opc.c (powerpc_opcodes): Reorder the opcode table so that instructions from newer processors are listed before older ones. <"icblce", "sync", "eieio", "tlbld">: Deprecate for processors that have instructions with conflicting opcodes. --- opcodes/ppc-dis.c | 24 +++++++++++------------- 1 file changed, 11 insertions(+), 13 deletions(-) (limited to 'opcodes/ppc-dis.c') diff --git a/opcodes/ppc-dis.c b/opcodes/ppc-dis.c index 2cbbec84a7..85113450a1 100644 --- a/opcodes/ppc-dis.c +++ b/opcodes/ppc-dis.c @@ -226,15 +226,12 @@ powerpc_init_dialect (struct disassemble_info *info) arg = end; } - if ((dialect & ~(PPC_OPCODE_ANY | PPC_OPCODE_32 | PPC_OPCODE_64)) == 0) + if ((dialect & ~(PPC_OPCODE_32 | PPC_OPCODE_64)) == 0) { - if ((dialect & (PPC_OPCODE_32 | PPC_OPCODE_64)) == 0) - { - if (info->mach == bfd_mach_ppc64) - dialect |= PPC_OPCODE_64; - else - dialect |= PPC_OPCODE_32; - } + if (info->mach == bfd_mach_ppc64) + dialect |= PPC_OPCODE_64; + else + dialect |= PPC_OPCODE_32; /* Choose a reasonable default. */ dialect |= (PPC_OPCODE_PPC | PPC_OPCODE_COMMON | PPC_OPCODE_CLASSIC | PPC_OPCODE_601 | PPC_OPCODE_ALTIVEC); @@ -338,6 +335,7 @@ print_insn_powerpc (bfd_vma memaddr, const struct powerpc_opcode *opcode; const struct powerpc_opcode *opcode_end; unsigned long op; + ppc_cpu_t dialect_orig = dialect; status = (*info->read_memory_func) (memaddr, buffer, 4, info); if (status != 0) @@ -376,7 +374,7 @@ print_insn_powerpc (bfd_vma memaddr, if ((insn & opcode->mask) != opcode->opcode || (opcode->flags & dialect) == 0 - || (opcode->deprecated & dialect) != 0) + || (opcode->deprecated & dialect_orig) != 0) continue; /* Make two passes over the operands.
