Thanks, Andrew Pinski
2005-03-06 Andrew Pinski <pinskia@physics.uc.edu> PR tree-opt/17671 * tree-ssa-phiopt.c (tree_ssa_phiopt): Rewrite so we base the bbs on the COND_EXPR instead of the PHI_NODEs. (candidate_bb_for_phi_optimization): Remove. (replace_phi_with_stmt): Rename to ... (replace_phi_edge_with_variable): this and change so that we replace the phi argument instead of removing the PHI. (conditional_replacement): Change so we deal with PHI with more than two arguments. (value_replacement): Likewise. (abs_replacement): Likewise.
PR tree-opt/17671 * gcc.dg/tree-ssa/phi-opt-[1-4].c: New tests.
