[GCC][PATCH] arm: Add pacbti related multilib support for armv8.1-m.main.
Hi,
This patch supports following -march/-mbranch-protection combination by linking them
to existing pacbti multilibs.
$ -march=armv8.1-m.main+pacbti+fp.dp+mve.fp -mbranch-protection=standard -mfloat-abi=hard -mthumb
$ -march=armv8.1-m.main+pacbti+fp.dp+mve -mbranch-protection=standard -mfloat-abi=hard -mthumb
$ -march=armv8.1-m.main+dsp+pacbti+fp.dp -mbranch-protection=standard -mfloat-abi=hard -mthumb
Regression tested on arm-none-eabi and bootstrapped on arm-none-linux-gnueabihf.
Ok for master?
Regards,
Srinath.
