GCC modified for the FreeChainXenon project

* fold-const.c (const_binop): Avoid performing the FP operation at compile-time, if either operand is NaN and we honor signaling NaNs, or if we're dividing by zero and either flag_trapping_math is set or the desired mode doesn't support infinities. (fold_initializer): New function to fold an expression ignoring any potential run-time exceptions or traps. * tree.h (fold_initializer): Prototype here. * c-typeck.c (build_binary_op): Move to the end of the file so that intializer_stack is in scope. If constructing an initializer, i.e. when initializer_stack is not NULL, use fold_initializer to fold expressions. * simplify-rtx.c (simplify_binary_operation): Likewise, avoid performing FP operations at compile-time, if they would raise an exception at run-time.

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*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
