PR rtl-optimization/27616 * cse.c (table_size): New static variable. (new_basic_block): Initialize it to 0. (remove_from_table): Decrement it. (insert): Increment it. (fold_rtx_mem_1): New function, renamed from fold_rtx_mem. (fold_rtx_mem): Enforce a cap on the recursion depth. Call fold_rtx_mem_1 if under the cap. (fold_rtx) <RTX_COMM_ARITH>: In the associative case, delay a little the lookup of the equivalent expression and test for equality of the first operand of the equivalent expression before in turn looking up an equivalent constant for the second operand.

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.
