--- Comment #1 from Joseph S. Myers  ---
Note that transforming x % 1 % -1 to x % -1 wouldn't strictly be valid (because
of undefined behavior from INT_MIN % -1), though hopefully cases with constant
1 or -1 get optimized to 0 anyway and the undefined behavior is only a problem
with a -1 that's not a constant.
