Hi,
This patch adds AArch32 support for -march=armv8.9-a and
-march=armv9.4-a. The behaviour of the new options can be
expressed using a combination of existing feature flags
and tables.
The cpu_arch_ver entries for ARM_ARCH_V9_4A and ARM_ARCH_V8_9A
are technically redundant but it including them for macro code
consistency across architectures.
Regression testing for arm-none-eabi target and found no regressions.
Ok for binutils-master?
Regards,
Srinath.

Hi,
(Rebased)
This patch adds AArch32 support for -march=armv8.9-a and
-march=armv9.4-a. The behaviour of the new options can be
expressed using a combination of existing feature flags
and tables.
The cpu_arch_ver entries for ARM_ARCH_V9_4A and ARM_ARCH_V8_9A
are technically redundant but it including them for macro code
consistency across architectures.
Regression testing for arm-none-eabi target and found
no regressions.
Ok for binutils-master?
Regards,
Srinath.
