6893 * simplify-rtx.c (simplify_gen_relational): Allow the cmp_mode
6894 argument to be VOIDmode, taking the mode of the comparison from
6895 the operands. Only call simplify_relational_operation if we
6896 know the mode of the comparison. Honor FLOAT_STORE_FLAG_VALUE
6897 if comparison has a floating point result. Ensure that the
6898 result is always of the specified mode.
6899 (simplify_replace_rtx): Simplify call to simplify_gen_relational.
6900 (simplify_unary_operation): Ensure the correct mode and cmp_mode
6901 are always passed to simplify_gen_relational. Simplify NOT of
6902 comparison operator in any mode, not just BImode.
6903 (simplify_ternary_operation): Correct tests on the return value
6904 of simplify_relational_operation to use const_true_rtx, not
6905 const1_rtx. Abort if it ever returns a non-constant result.
6907 * cfgloopanal.c (count_strange_loop_iterations): Use the function
6908 simplify_relational_operation, not simplify_gen_relational, if
6909 we're only interested in constant comparisons and will ignore
6910 non-constant results.

6914 * fold-const.c (tree_swap_operands_p): New function to determine
6915 the prefered ordering of operands.
6916 (fold): Numerous clean-ups. Use tree_swap_operands_p when swapping
6917 operands to commutative, comparison or ternary operators. Replace
6918 uses of TREE_SET_CODE with recursive call to fold. Remove duplicate
6919 transformation of A ? B : C into !A ? C : B.

10629 (fold_builtin): Don't rewrite pow(x,2.0) as x*x nor pow(x,-2.0)
10630 as 1.0/(x*x). This avoids unbounded recursion as we now prefer
