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.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
