aarch64: Improve naming conventions for A and R-profile architecture
Historically, flags and variables relating to architectural revisions for the A-profile architecture omitted the trailing `A' such that, for example, assembling for `-march=armv8.4-a' set the `AARCH64_ARCH_V8_4' flag in the assembler. This leads to some ambiguity, since Binutils also targets the R-profile Arm architecture. Therefore, it seems prudent to have everything associated with the A-profile cores end in `A' and likewise `R' for the R-profile. Referring back to the example above, the flag set for `-march=armv8.4-a' is better characterized if labeled `AARCH64_ARCH_V8_4A'. The only exception to the rule of appending `A' to variables is found in the handling of the `AARCH64_FEATURE_V8' macro, as it is the baseline from which ALL processors derive and should therefore be left unchanged. In reflecting the `ARM' architectural nomenclature choices, where we have `ARM_ARCH_V8A' and `ARM_ARCH_V8R', the choice is made to not have an underscore separating the numerical revision number and the A/R-profile indicator suffix. This has meant that renaming of R-profile related flags and variables was warranted, thus going from `.*_[vV]8_[rR]' to `.*_[vV]8[rR]'. Finally, this is more in line with conventions within GCC and adds consistency across the toolchain. gas/ChangeLog: * gas/config/tc-aarch64.c: (aarch64_cpus): Reference to arch feature macros updated.
