tree-vn.c (expressions_equal_p): Do not check type equality or compatibility before calling operand_equal_p.
2008-04-17 Richard Guenther <rguenther@suse.de>
* tree-vn.c (expressions_equal_p): Do not check type
equality or compatibility before calling operand_equal_p.
* fold-const.c (operand_equal_p): Check equivalence of
integer constants before bailing out due to signedness or
precision differences.
* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Ignore
spurious differences in type qualification. Ignore types
for COMPONENT_REFs at all.
* gcc.dg/tree-ssa/ssa-fre-17.c: New testcase.
