| Summary | 0000543: gcc may compile for x86-64-v3 on x86_64_v2 system | ||||
| Description | I was suprised to find that gcc was producing code using -march=x86-64-v3 on an AlmaLinux x86_64_v2 system. I traced the problem to having redhat-rpm-config installed. We like to get the additional flags from redhat-rpm-config for security, hardening, etc. I see that you provide /etc/rpm/macros.x86_64_v2 that defines %target_platform and %x86_64_v2. I think that you should add the following line to select -march=x86-64-v2 whenever redhat-rpm-config is installed: %__cflags_arch_x86_64_level -v2 That way, the correct microarchitecture is always selected by gcc. | ||||
| Steps To Reproduce | Check the value of CFLAGS and CXXFLAGS when building a package with rpmbuild and redhat-rpm-config is installed. | ||||
| Additional Information | I tried to select AlmaLinux-10 for the category. However, only "[All Projects] General" was available to me. | ||||
