4980 * simplify-rtx.c (simplify_gen_relational): Allow the cmp_mode
4981 argument to be VOIDmode, taking the mode of the comparison from
4982 the operands. Only call simplify_relational_operation if we
4983 know the mode of the comparison. Honor FLOAT_STORE_FLAG_VALUE
4984 if comparison has a floating point result. Ensure that the
4985 result is always of the specified mode.
4986 (simplify_replace_rtx): Simplify call to simplify_gen_relational.
4987 (simplify_unary_operation): Ensure the correct mode and cmp_mode
4988 are always passed to simplify_gen_relational. Simplify NOT of
4989 comparison operator in any mode, not just BImode.
4990 (simplify_ternary_operation): Correct tests on the return value
4991 of simplify_relational_operation to use const_true_rtx, not
4992 const1_rtx. Abort if it ever returns a non-constant result.
4994 * cfgloopanal.c (count_strange_loop_iterations): Use the function
4995 simplify_relational_operation, not simplify_gen_relational, if
4996 we're only interested in constant comparisons and will ignore
4997 non-constant results.

5003 (fold): Numerous clean-ups. Use tree_swap_operands_p when swapping
5004 operands to commutative, comparison or ternary operators. Replace
5005 uses of TREE_SET_CODE with recursive call to fold. Remove duplicate
5006 transformation of A ? B : C into !A ? C : B.
