Which compiler is this? Good point. I am using: # gcc --version gcc (GCC) 11.5.0 20240719 (Red Hat 11.5.0-2) Clang, on the other hand, isn't upset about it. # clang --target=aarch64-redhat-linux-gnu -fintegrated-as -Wall -O2 -g -I/home/leit/Devel/upstream/tools/testing/selftests/ -isystem /home/leit/Devel/upstream/usr/include -I/home/leit/Devel/upstream/tools/include -std=gnu99 -I. -Wno-address-of-packed-member -Wno-gnu-variable-sized-type-not-at-end -D_GNU_SOURCE= testcases/fpmr_siginfo.c test_signals.c test_signals_utils.c testcases/testcases.c signals.S sve_helpers.c -o testcases/fpmr_siginfo # clang --version clang version 19.1.3 (CentOS 19.1.3-1.el9)
