re PR rtl-optimization/3995 (i386 optimisation: joining tests)
PR opt/3995
* fold-const.c (sign_bit_p): New function.
(fold) [EQ_EXPR]: Use this to convert (A & C) == 0 into A >= 0 and
(A & C) != 0 into A < 0, when constant C is the sign bit of A's type.
Reapply fold when converting (A & C) == C into (A & C) != 0.
(fold_binary_op_with_conditional_arg): Fix typo in comment.
testsuite/
* gcc.c-torture/execute/20020506-1.c: New test case.
