* builtins.c (fold_builtin_bitop): New function to perform constant folding of ffs, clz, ctz, popcount and parity builtin functions and their long and long long variants (such as ffsl and ffsll). (fold_builtin): fold_builtin_bitop when appropriate. * simplify-rtx.c (simplify_unary_operation): Honor both CLZ_DEFINED_VALUE_AT_ZERO and CTZ_DEFINED_VALUE_AT_ZERO when evaluating clz and ctz at compile-time, for operands wider than HOST_WIDE_INT.

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.
