This patch adds -march=armv8.5-a to the Arm backend. Armv8.5-A also adds two new security features: - Speculation Barrier instruction - Execution and Data Prediction Restriction Instructions These are made optional to all older Armv8-A versions. Thus we are adding two new options "+sb" and "+predres" to all older Armv8-A. These are passed on to the assembler and have no code generation effects and have already gone in the trunk of binutils. *** gcc/ChangeLog *** 2018-11-12 Sudakshina Das <sudi.das@arm.com> * config/arm/arm-cpus.in (armv8_5, sb, predres): New features. (ARMv8_5a): New fgroup. (armv8.5-a): New arch. (armv8-a, armv8.1-a, armv8.2-a, armv8.3-a, armv8.4-a): New options sb and predres. * config/arm/arm-tables.opt: Regenerate. * config/arm/t-aprofile: Add matching rules for -march=armv8.5-a * config/arm/t-arm-elf (all_v8_archs): Add armv8.5-a. * config/arm/t-multilib (v8_5_a_simd_variants): New variable. Add matching rules for -march=armv8.5-a and extensions. * doc/invoke.texi (ARM options): Document -march=armv8.5-a. Add sb and predres to all armv8-a except armv8.5-a. *** gcc/testsuite/ChangeLog *** 2018-11-12 Sudakshina Das <sudi.das@arm.com> * gcc.target/arm/multilib.exp: Add some -march=armv8.5-a combination tests.

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.
