rs6000: Delete many HAVE_AS_* (PR87149)
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)
PR target/87149
* config.in (HAVE_AS_CMPB, HAVE_AS_DFP, HAVE_AS_FPRND, HAVE_AS_MFPGPR,
HAVE_AS_POPCNTB, HAVE_AS_POPCNTD, HAVE_AS_POWER8, HAVE_AS_POWER9):
Delete, always treat as true.
* config/powerpcspe/powerpcspe.c (rs6000_option_override_internal):
Ditto. Simplify remaining code.
* config/powerpcspe/powerpcspe.h: Ditto.
* config/rs6000/rs6000.c (rs6000_option_override_internal): Ditto.
Simplify remaining code.
(rs6000_expand_builtin): Ditto.
* config/rs6000/rs6000.h: Ditto.
* configure.ac: Ditto.
* configure: Regenerate.
