[GCC, ARM] Enable armv8.5-a and add +sb and +predres for previous ARMv8-a in ARM
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.
