8 * simplify-rtx.c (simplify_gen_relational): Allow the cmp_mode
9 argument to be VOIDmode, taking the mode of the comparison from
10 the operands. Only call simplify_relational_operation if we
11 know the mode of the comparison. Honor FLOAT_STORE_FLAG_VALUE
12 if comparison has a floating point result. Ensure that the
13 result is always of the specified mode.
14 (simplify_replace_rtx): Simplify call to simplify_gen_relational.
15 (simplify_unary_operation): Ensure the correct mode and cmp_mode
16 are always passed to simplify_gen_relational. Simplify NOT of
17 comparison operator in any mode, not just BImode.
18 (simplify_ternary_operation): Correct tests on the return value
19 of simplify_relational_operation to use const_true_rtx, not
20 const1_rtx. Abort if it ever returns a non-constant result.
22 * cfgloopanal.c (count_strange_loop_iterations): Use the function
23 simplify_relational_operation, not simplify_gen_relational, if
24 we're only interested in constant comparisons and will ignore

29 * fold-const.c (tree_swap_operands_p): New function to determine
30 the prefered ordering of operands.

32 operands to commutative, comparison or ternary operators. Replace
33 uses of TREE_SET_CODE with recursive call to fold. Remove duplicate
34 transformation of A ? B : C into !A ? C : B.
