* tree-ssa-ccp.c (latticevalue): Add UNKNOWN_VAL. (substitute_and_fold): Propigate into VUSE operands when possible. (visit_phi_node): Handle UNKNOWN_VAL latticevalue. (cp_lattice_meet): Handle merging of latticevalues when UNKNOWN_VAL is present. (visit_stmt): Visit assignments with V_MUST_DEFs. (visit_assignment): Gather ccp information for V_MUST_DEF operands. (ccp_fold): Deal with RHS' that are constant and virtual. (evaluate_stmt): Handle UNKNOWN_VAL likely values. (dump_lattice_value): Dump UNKNOWN_VAL latticevalues. (initialize): Mark statements with V_MUST_DEFs as VARYING only if the V_MUST_DEF operand is VARYING. Fix comment and include VOPS when computing immediate uses. (set_lattice_value): Disallow a UNKNOWN_VAL->UNDEFINED state transition. (replace_vuse_in): New function. (likely_value): Add check of vuse operands. (get_default_value): Set the default value of virtually defined variables to UKNOWN_VAL instead of VARYING. testsuite: * gcc.dg/tree-ssa/20040721-1.c: New test. From-SVN: r85055
