-René's patch seems to have stalled, so here is an updated version of the
-patch with the requested changes to his patch.
-
-I'll note I have added an additional code change, which is to also emit a
-".machine altivec" if Altivec is enabled.  The problem this fixes is for
-cpus like the G5, which is basically a power4 plus an Altivec unit, its
-".machine power4" doesn't enable the assembler to recognize Altivec insns.
-That isn't a problem if you use gcc -mcpu=G5 to assemble the assembler file,
-since gcc passes -maltivec to the assembler.  However, if you try to assemble
-the assembler file with as by hand, you'll get "unrecognized opcode" errors.
-I did not do the same for VSX, since all ".machine <cpu>" for cpus that
-support VSX already enable VSX insn recognition, so it's not needed.

-rs6000: Fix .machine cpu selection w/ altivec [PR97367]
-
-There are various non-IBM CPUs with altivec, so we cannot use that
-flag to determine which .machine cpu to use, so ignore it.
-Emit an additional ".machine altivec" if Altivec is enabled so
-that the assembler doesn't require an explicit -maltivec option
-to assemble any Altivec instructions for those targets where
-the ".machine cpu" is insufficient to enable Altivec.  For example,
--mcpu=G5 emits a ".machine power4".
-
-This passed bootstrap and regtesting on powrpc64-linux (running the testsuite
-in both 32-bit and 64-bit modes) with no regressions.
-
-Ok for trunk and the release branches after some trunk burn-in time?
