This patch simplifies the table of CPUs supported in GCC by making use of the new alias feature. Most of the changes are fairly straight-forward: - arm7tdmi and arm7tdmi-s are the same thing. - arm710t, arm720t and arm740t differ only in features external to the core - arm920 and arm920t are the same thing; arm922t and arm940t differ from arm920t only in features external to the core; ep9312 is an arm920t-derived core that we continue to recognize for legacy reasons. - arm10tdmi and arm1020t differ only in features external to the core. - arm9e, arm946te-s, arm966e-s and arm968e-s differ only in features external to the core. - arm10e, arm1020e and arm1022e differ only in features external to the core. The arm10e/arm1020e/arm1022e change is the only one which changes behaviour of the compiler slightly. Previously, and for no reason that I can remember, the scheduler for arm1020e/arm1022e was not used for arm10e: this was probably an oversight. The unification means that the same scheduler is now used for all three cores. * config/arm/arm-cpus.in (arm7tdmi): Add an alias for arm7tdmi-s. (arm7tdmi-s): Delete CPU. (arm710t): Add aliases for arm720t and arm740t. (arm720t, arm740t): Delete CPUs. (arm920t): Add aliases for arm920, arm922t and arm940t. (arm920, arm922t, arm940t): Delete CPUs. (arm10tdmi): Add alias for arm1020t. (arm1020t): Delete CPU. (arm9e): Add aliases for arm946e-s, arm966e-s and arm968e-s. (arm946e-s, arm966e-s, arm968e-s): Delete CPUs. (arm10e): Add aliases for arm1020e and arm1022e. (arm1020e, arm1022e): Delete CPU. * config/arm/arm.md (generic_sched): Remove entries that are now handled by aliases. (generic_vfp): Likewise. * config/arm/arm1020e.md: Simplify tuning selection based on alias changes. * config/arm/arm-tune.md: Regenerated. * config/arm/arm-tables.opt: Regenerated.

README
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.
