Hello,
ARMv8.1 is a set of architectural extensions to ARMv8. Support has been
enabled in binutils for ARMv8.1 for the architechure, using the name
"armv8.1-a".
This patch adds support to gcc for specifying an ARMv8.1 architecture
using options "-march=armv8.1-a" and "-march=armv8.1-a+crc". It also
adds the FPU options "-mfpu=neon-fp-armv8.1" and
"-mpu=crypto-neon-fp-armv8.1", to specify the ARMv8.1 Adv.SIMD
instruction set. The changes set the apropriate architecture and fpu
options for binutils but don't otherwise change the code generated by
gcc.
Tested for arm-none-linux-gnueabihf with native bootstrap and make
check.
Ok for trunk?
Matthew
2015-09-17 Matthew Wahab <matthew.wahab@arm.com>

Ping.
Updated patch attached, I've broken the over-long lines added to arm-arches.def and
arm-fpus.def.

Some of the command line options may be unnecessary so I'll drop this patch.
