Subject: [PATCH] IBM zSystems: Fix predicate execute_operation
Date: Sat, 11 Feb 2023 17:10:45 +0100 [thread overview]
Message-ID: <20230211161044.3540594-1-stefansf@linux.ibm.com> (raw)
Use constrain_operands in order to check whether there exists a valid
alternative instead of extract_constrain_insn which ICEs in case no
alternative is found.
Bootstrapped and regtested on IBM zSystems. Ok for mainline?
gcc/ChangeLog:
* config/s390/predicates.md (execute_operation): Use
constrain_operands instead of extract_constrain_insn in order to
determine wheter there exists a valid alternative.
