This patch is part of a series that enables ARMv8.5-A in GCC and adds Branch Target Identification Mechanism. This patch add all the command line feature that are added by ARMv8.5. Optional extensions to armv8.5-a: +rng : Random number Generation Instructions. +memtag : Memory Tagging Extension. ARMv8.5-A features that are optional to older arch: +sb : Speculation barrier instruction. +ssbs: Speculative Store Bypass Safe instruction. +predres: Execution and Data Prediction Restriction instructions. All of the above only effect the assembler and have already gone in the trunk of binutils. *** gcc/ChangeLog *** 2018-01-09 Sudakshina Das <sudi.das@arm.com> * config/aarch64/aarch64-option-extensions.def: Define AARCH64_OPT_EXTENSION for memtag, rng, sb, ssbs and predres. * gcc/config/aarch64/aarch64.h (AARCH64_FL_RNG): New. (AARCH64_FL_MEMTAG, ARCH64_FL_SB, AARCH64_FL_SSBS): New. (AARCH64_FL_PREDRES): New. (AARCH64_FL_FOR_ARCH8_5): Add AARCH64_FL_SB, AARCH64_FL_SSBS and AARCH64_FL_PREDRES by default. * gcc/doc/invoke.texi: Document rng, memtag, sb, ssbs and predres. From-SVN: r267766 |

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.
