Remove ppc860, ppc750cl, ppc7450 insns from common ppc.
Back in the day support for these processors was added, we probably didn't want to waste PPC_OPCODE bits on minor variations. I've had a complaint that disassembly of mfspr/mtspr was wrong for power8. This patch fixes that problem. Note that since -m860/-m850/-m821 are new gas options enabling the mpc8xx specific mfspr/mtspr variants it is possible that this change will break some mpc8xx assembly code. ie. you might need to modify makefiles to pass -m860 to gas. include/opcode/ * ppc.h (PPC_OPCODE_750, PPC_OPCODE_7450, PPC_OPCODE_860): Define. opcodes/ * ppc-opc.c (PPC750, PPC7450, PPC860): Define using PPC_OPCODE_*. * ppc-dis.c (ppc_opts): Add 821, 850 and 860 entries. Add PPC_OPCODE_7450 to 7450 entry. Add PPC_OPCODE_750 to 750cl entry. gas/ * config/tc-ppc.c (md_show_usage): Add -m821, -m850, -m860. * doc/c-ppc.texi (PowerPC-Opts): Likewise. gas/testsuite/ * gas/ppc/titan.d: Correct mfmcsrr0 disassembly.
