[PATCH] rs6000: Delete many HAVE_AS_* (PR87149)
Segher Boessenkool
segher@kernel.crashing.org
Thu Sep 27 19:47:00 GMT 2018
This deletes most HAVE_AS_* that determine if the assembler supports
some ISA level (and also HAVE_AS_MFPGPR and HAVE_AS_DFP).
These are not useful: we will only generate an instruction that requires
some newer ISA if the user specifically asked for it (with -mcpu=, say).
If the assembler cannot handle that, it is fine if it gives an error.
They also hurt: it increases the number of possible situations that all
need handling and all need testing. We do not handle all cases, and
obviously do not test all either.
This patch removes:
HAVE_AS_POPCNTB (power5, 2.02)
HAVE_AS_FPRND (power5+, 2.04)
HAVE_AS_CMPB (power6, 2.05)
HAVE_AS_POPCNTD (power7, 2.06)
HAVE_AS_POWER8 (power8, 2.07)
HAVE_AS_POWER9 (power9, 3.0)
HAVE_AS_DFP (power6, 2.05, server)
HAVE_AS_MFPGPR (power6x but not later, not arch)
Later patches will tie up some loose ends (LWSYNC, DCI, MFCRF, specs)
that are easier handled separately for various reasons.
This also adjusts the powerpcspe port because the configuration parts
are still shared (none of it applies to any cpu supported by the
powerpcspe port). Andrew, I hope you don't mind.
Tested on powerpc-linux, powerpc64-linux, powerpc64le-linux, powerpc-aix.
Committing.
