There is no need to compare nonzero masks when comparing two VARYING ranges, as they are always the same when range types are the same. gcc/ChangeLog: * value-range.cc (irange::legacy_equal_p): Remove nonozero mask check when comparing VR_VARYING ranges. --- gcc/value-range.cc | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-)
