--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Jan 14 15:25:22 2016 New Revision: 232368 URL: https://gcc.gnu.org/viewcvs?rev=232368&root=gcc&view=rev Log: PR middle-end/68146 PR tree-optimization/69155 * tree-complex.c: Include cfganal.h. (phis_to_revisit): New variable. (extract_component): Add phiarg_p argument. Assert that returned SSA_NAME has non-NULL SSA_NAME_DEF_STMT unless phiarg_p is true. (update_phi_components): Partly rewrite to use loop over real/imag components instead of code duplication. If extract_component returns SSA_NAME with NULL SSA_NAME_DEF_STMT, store SSA_NAME_VAR or create_tmp_reg into the PHI node instead, and mention the phi triplet in phis_to_revisit. (tree_lower_complex): Walk bbs in rpo order. Adjust phis recorded in phis_to_revisit at the end. * gfortran.dg/pr68146.f: New test. * gfortran.dg/pr69155.f90: New test.
