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.
