--- Comment #25 from Sam James <sjames at gcc dot gnu.org> --- (In reply to H.J. Lu from comment #24) > Created attachment 61789 [details] > A patch to add --enable-x86-64-mfentry When wouldn't we want this enabled? Is it just a configure option because of a small risk of regressions? i.e. Once I've tested this, I surely want to ship our distro GCC with it enabled?
