PowerPC register expression checks
This stops powerpc gas blithely accepting such nonsense as
"addi %f4,%cr3,%r31".
PR 21118
gas/
* NEWS: Mention powerpc register checks.
* config/tc-ppc.c (struct pd_reg): Make value a short. Add flags.
(pre_defined_registers): Delete fpscr and pmr entries. Set
register type in flags.
(cr_names): Set type in flags.
(reg_name_search): Return pointer to struct pd_reg rather than value.
(register_name): Adjust to suit. Set X_md from flags.
(ppc_parse_name): Likewise.
(ppc_optimize_expr): New function.
(md_assemble): Verify expresion reg flags match operand.
* config/tc-ppc.h (md_optimize_expr): Define.
(ppc_optimize_expr): Declare.
include/
* opcode/ppc.h (PPC_OPERAND_*): Reassign values, regs first.
(PPC_OPERAND_SPR, PPC_OPERAND_GQR): Define.
opcodes/
* ppc-opc.c (powerpc_operands): Flag SPR, SPRG and TBR entries
with PPC_OPERAND_SPR. Flag PSQ and PSQM with PPC_OPERAND_GQR.
