--- Comment #32 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Created attachment 32312 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32312&action=edit New patch for case in comment 21 This is just a preliminary runtime patch. Without: real 0m7.519s user 0m7.496s sys 0m0.000s With patch: real 0m1.433s user 0m1.424s sys 0m0.002s Which is not a bad improvement. I am still looking at what we could do on the front-end.
