I'm not adding a testcase here as we intend to remove the tunable for GCC 12 anyway (the new costing logic will remain and will benefit from this extra check, but the -moverride option will no longer exist). gcc/ChangeLog: PR target/99820 * config/aarch64/aarch64.c (aarch64_analyze_loop_vinfo): Check for available issue_info before using it.
