Add basic armv8-a support
2012-10-17 Matthew Gretton-Dann <matthew.gretton-dann@arm.com>
* config/arm/lib1funcs.S (__ARM_ARCH__): Define for ARMv8-A.
2012-10-17 Matthew Gretton-Dann <matthew.gretton-dann@arm.com>
* gcc.target/arm/ftest-armv8a-arm.c: New testcase.
* gcc.target/arm/ftest-armv8a-thumb.c: Likewise.
* gcc.target/arm/ftest-support-arm.h (feature_matrix): Add
ARMv8-A row.
* gcc.target/arm/ftest-support-thumb.h (feature_matrix):
Likewise.
* gcc.target/arm/ftest-support.h (architecture): Add ARMv8-A.
* lib/target-supports.exp: Add ARMv8-A architecture expectation.

Ramana Radhakrishnan <ramana.radhakrishnan@arm.com>
* config.gcc: Add support for ARMv8 for arm*-*-* targets.
* config/arm/arm-arches.def: Add armv8-a
* config/arm/arm-fpus.def: Add fp-armv8, neon-fp-armv8,
crypto-neon-fp-armv8. Add crypto field.
* config/arm/arm-tables.opt: Regenerate.
* config/arm/arm.c (FL_FOR_ARCH8A): Likewise.
(arm_arch8): New global variable.
(ARM_FPU): Add crypto parameter.
(arm_option_override): Set arm_arch8, update comments.
* config/arm/arm.h (TARGET_CRYPTO): New macro.
(arm_fpu_desc): Add crypto field.
(base_architecture): Add ARMv8 entry.
