--- Comment #9 from Kewen Lin <linkw at gcc dot gnu.org> --- (In reply to Michael Meissner from comment #8) > Note, the gcc.target/powerpc/pr92398.p9-.c test fails when the compiler is > configured for either --with-cpu=power9 or --with-cpu=power10. No > --with-tune= was used in configuring either compiler. Yeah, as comment #1, it's a different issue from the --with-tune issue, it's due to empty TU in effective target checks.
