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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
