The mitigation was introduced after the test, and enabled by default for the selected processor, a72. Select a53 instead, where the migitation is not enabled by default, and all the expected fusions can take place. for gcc/testsuite/ChangeLog * gcc.target/arm/aes-fuse-1.c: Switch to -mcpu=cortex-a53. * gcc.target/arm/aes-fuse-2.c: Likewise.
