commit ef5a96d564a22a25d31533c7377eede42c12b25c

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.
