Hi,
This patch adds the -march feature +pacbti to Armv8.1-M Mainline.
This feature enables pointer signing and authentication instructions
on M-class architectures.
Tested on arm-none-eabi. OK for trunk?
2021-10-04 Tejas Belagod <tbela...@arm.com>
gcc/Changelog:
* config/arm/arm-cpus.in: Define new feature pacbti.
* config/arm/arm.h (TARGET_HAVE_PACBTI): New.
"+pacbti" needs to be documented in invoke.texi at the appropriate place.
Thanks for the reviews.

This isn't in the correct style:
gcc/Changelog:
* config/arm/arm.h (TARGET_HAVE_PACBTI): New macro.
* config/arm/arm-cpus.in (pacbti): New feature.
* doc/invoke.texi (Arm Options): Document it.
would be better.
Tested the following configurations, OK for trunk?
-mthumb/-march=armv8.1-m.main+pacbti/-mfloat-abi=soft
-marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp
mcmodel=small and tiny
aarch64-none-linux-gnu native test and bootstrap
R.
Otherwise OK.
R.
