Subject: [PATCH] rs6000: Fix some issues related to Power10 fusion [PR104024]
Date: Wed, 30 Nov 2022 16:30:13 +0800 [thread overview]
Message-ID: <009fda27-7119-6de8-8dbe-51126bdfca12@linux.ibm.com> (raw)
Hi,
As PR104024 shows, the option -mpower10-fusion isn't guarded by
-mcpu=power10, it causes compiler to fuse for some patterns
even without power10 support and then causes ICE unexpectedly,
this patch is to simply unmask it without power10 support, not
emit any warnings as this option is undocumented.
Besides, for some define_insns in fusion.md which use constraint
v, it requires the condition VECTOR_UNIT_ALTIVEC_OR_VSX_P
(<MODE>mode), otherwise it can cause ICE in reload, see test
case pr104024-2.c.
Bootstrapped and regtested on powerpc64-linux-gnu P8,
powerpc64le-linux-gnu P9 and P10.
Is it ok for trunk?
BR,
Kewen
