PowerPC32 extended instructions in powerpc_macros
As for PowerPC64, move instructions to the main opcode table. opcodes/ * ppc-opc.c (insert_crwn, extract_crwn, insert_elwn, extract_elwn), (insert_erwn, extract_erwn, insert_erwb, extract_erwb), (insert_cslwn, extract_cslwb, insert_ilwb, extract_ilwn), (insert_irwb, extract_irwn, insert_rrwn, extract_rrwn), (insert_slwn, extract_slwn, insert_srwn, extract_srwn): New functions. (CRWn, ELWn, ERWn, ERWb, CSLWb, CSLWn, ILWn, ILWb, IRWn, IRWb), (RRWn, SLWn, SRWn): Define and add powerpc_operands entries. (MMB_MASK, MME_MASK, MSHMB_MASK): Define. (powerpc_opcodes): Add "inslwi", "insrwi", "rotrwi", "clrrwi", "slwi", "srwi", "extlwi", "extrwi", "sli", "sri" and corresponding record (ie. dot suffix) forms. (powerpc_macros): Delete same. gas/ * testsuite/gas/ppc/476.d: Update. * testsuite/gas/ppc/simpshft.d: Update.
