PR bootstrap/12269 * simplify-rtx.c (simplify_gen_relational): Allow the cmp_mode argument to be VOIDmode, taking the mode of the comparison from the operands. Only call simplify_relational_operation if we know the mode of the comparison. Honor FLOAT_STORE_FLAG_VALUE if comparison has a floating point result. Ensure that the result is always of the specified mode. (simplify_replace_rtx): Simplify call to simplify_gen_relational. (simplify_unary_operation): Ensure the correct mode and cmp_mode are always passed to simplify_gen_relational. Simplify NOT of comparison operator in any mode, not just BImode. (simplify_ternary_operation): Correct tests on the return value of simplify_relational_operation to use const_true_rtx, not const1_rtx. Abort if it ever returns a non-constant result. * cfgloopanal.c (count_strange_loop_iterations): Use the function simplify_relational_operation, not simplify_gen_relational, if we're only interested in constant comparisons and will ignore non-constant results.
