--- Comment #2 from Gaius Mulley <gaius at gcc dot gnu.org> --- Created attachment 57891 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57891&action=edit Proposed fix Here is a proposed fix which stores the result of the relop as a constant. The fix requires M2Quads to mark a const expression relop and M2GenGCC to evaluate the relop and then to remove the redundant quadruples.
