when debugging expmed.[ch] for PR/108987 saw that some of the cost arrays have less than ideal layout as follows: x_shift*cost[0..63][speed][modes] We would want speed to be first index since a typical compile will have that fixed, followed by mode and then the shift values. It should be non-functional from compiler semantics pov, except executing slightly faster due to better locality of shift values for given speed and mode. And also a bit more intutive when debugging. gcc/Changelog: * expmed.h (x_shift*_cost): convert to int [speed][mode][shift]. (shift*_cost_ptr ()): Access x_shift*_cost array directly.

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.
