This modules-related patch extends cache_integer_cst. Currently, when given a small cst, that cst is added to the type's small and /must not/ already be there. Large values are fine if they are already in the large cache. This adds a parameter to indicate small duplicates are ok, and it returns the cached value -- either what was already tehre, or the newly inserted const. gcc/ * tree.h (cache_integer_cst): Add defaulted might_duplicate parm. * tree.c (cache_integer_cst): Return the integer cst, add might_duplicate parm to permit finding a small duplicate.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
