gcc : ChangeLog tree-ssa.c
Log message:
* tree-ssa.c (verify_use): Fix comment.
(verify_phi_args): Check that the number of incoming edges matches
the number of PHI arguments. Check that each PHI argument is
either an SSA_NAME or an invariant. Coalesce tests for PHIs for
dead or duplicated edges. Clear e->aux earlier and avoid separate
loop to clear e->aux and test for missed edges.
(verify_ssa): Remove first walk over statements. Move checking
of PHI args into verify_phi_args. Move checking of statements
with aliased stores and V_MAY_DEFS into the remaining loop over
the statements. Register defs by walking through the formal
SSA_NAME table.
