Subject: [PATCH] middle-end: Skip initialization of opaque type register variables [PR103127]
Date: Mon, 29 Nov 2021 15:56:58 -0600 [thread overview]
Message-ID: <ccb5f603-5c1f-0e59-31d9-07251f81e0aa@linux.ibm.com> (raw)
Sorry for dropping the ball on testing the patch from the bugzilla!
The following patch fixes the ICE reported in the bugzilla on the pre-existing
gcc testsuite test case, bootstraps and shows no testsuite regressions
on powerpc64le-linux. Ok for trunk?
Peter
For -ftrivial-auto-var-init=*, skip initializing the register variable if it
is an opaque type, because CONST0_RTX(mode) is not defined for opaque modes.

PR middle-end/103127
* internal-fn.c (expand_DEFERRED_INIT): Skip if VAR_TYPE is opaque.
