--- Comment #3 from Xi Ruoyao <xry111 at gcc dot gnu.org> --- (define_code_iterator vfcond [unordered ordered eq ne le lt uneq unle unlt]) (define_code_attr fcc [(unordered "cun") (ordered "cor") (eq "ceq") (ne "cne") (uneq "cueq") (unle "cule") (unlt "cult") (le "cle") (lt "clt")]) This just looks wrong: not only "cne" should be "cune", but also "clt"/"cle" should be "slt"/"sle" instead (per C23 Annex F). It seems we should use the same thing as fcond in loongarch.md.
