PowerPC se_rfmci and VLE, SPE2 and LSP insns with -many
I noticed recently that se_rfmci, a VLE mode instruction, was being
accepted by non-VLE cpus, and also that se_rfmci by itself in a
section did not cause SHF_PPC_VLE to be set. ie. both testcases added
by this patch fail without the changes to tc-ppc.c here.
Also, VLE, SPE2 and LSP insns were not accepted by the assembler with
-many nor were SPE2 and LSP being disassembled with -Many.
gas/
* config/tc-ppc.c (ppc_setup_opcodes): Wrap long lines. Add
vle_opcodes when PPC_OPCODE_VLE or PPC_OPCODE_ANY. Simplify
disassembler index segment checks. Add LSP and SPE2 opcodes
when PPC_OPCODE_ANY too.
(md_assemble): Correct logic adding PPC_APUINFO_VLE and
SHF_PPC_VLE.
* testsuite/gas/ppc/se_rfmci.s
* testsuite/gas/ppc/se_rfmci.d,
* testsuite/gas/ppc/se_rfmci_bad.d: New tests.
* testsuite/gas/ppc/ppc.exp: Run them.
opcodes/
* ppc-dis.c (print_insn_powerpc): Disassemble SPE2 and LSP insn
when -Many.
* ppc-opc.c (vle_opcodes <se_rfmci>): Comment.
