H.J. Lu <hjl.tools at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed| |2022-10-18 Ever confirmed|0 |1 Status|UNCONFIRMED |NEW --- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> --- Since the default is -march=tigerlake, it enables AVX512 in the middle end. When "arch=alderlake" disables AVX512, we fails to expand AVX512 to non-AVX512 ISAs. It means that target_clones can't be more restrictive than the default. We should provide better diagnostics.
