--- Comment #5 from Sam James <sjames at gcc dot gnu.org> --- (In reply to Sam James from comment #2) > Created attachment 58826 [details] > reduction-2.ii I can try bisect this/original if I need to but I'd prefer not to, as it's a pain because of libstdc++ vs float128 vs modern glibc w/o fixincludes. I hit a few analyzer oddities with variations of the first testcase but if it's jump threading going wrong then I'm not going to worry about reporting those yet.
