Date: Wed, 19 Jan 2022 17:38:40 +0000 (GMT) [thread overview] Message-ID: <20220119173840.1B5963857C76@sourceware.org> (raw) https://gcc.gnu.org/g:d249933e6b46e05595fe4208da530c790b677ac0 commit r12-6748-gd249933e6b46e05595fe4208da530c790b677ac0 Author: Robin Dapp <rdapp@linux.ibm.com> Date: Thu Nov 28 13:26:56 2019 +0100 testsuite/s390: Add tests for noce_convert_multiple. Add new s390-specific tests that check if we convert two SETs into two loads on condition. Remove the s390-specific target-check in gcc.dg/ifcvt-4.c. gcc/testsuite/ChangeLog: * gcc.dg/ifcvt-4.c: Remove s390-specific check. * gcc.target/s390/ifcvt-two-insns-bool.c: New test. * gcc.target/s390/ifcvt-two-insns-int.c: New test. * gcc.target/s390/ifcvt-two-insns-long.c: New test.
