[AARCH64] Add scheduler for ThunderX
This adds the schedule model for ThunderX. There are a few TODOs in that not all of the SIMD is model currently. Also the idea of a simple shift/extend is not modeled and all cases where there is a shift/extend is considered as non simple and take up two cycles rather than correct value of one cycle. Also the 32bit divide and the 64bit divide have different cycle counts but there is no way to model that currently. Also multiply high takes one cycle more than the normal multiply but there is no way to model that currently either. Build and tested for aarch64-elf with no regressions. ChangeLog: * config/aarch64/aarch64-cores.def (thunderx): Change the scheduler over to thunderx. * config/aarch64/aarch64.md: Include thunderx.md. (generic_sched): Set to no for thunderx. * config/aarch64/thunderx.md: New file. From-SVN: r217593

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.
