--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 41031 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41031&action=edit second patch candidate Second candidate, instead of inhibiting PHI insertions this limits use of them during elimination. This should allow existing 2nd level opportunities to continue to be handled.
