PR optimization/12322 * gcse.c (struct ls_expr): Change type of hash_index from int to unsigned int. (hash_expr): Document hash_table_size parameter and wrap long line. (ldst_entry): Calculate expression's hash_index and record in ptr. (trim_ld_motion_mems): Use hash_index to search a single bucket instead of scanning the entire hash_table. Remove the "del" local variable and use the equivalent "expr == 0" instead. Change last to be a pointer to the pointer to the current element, to simplify and speed-up deleting from a linked list.

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.
