[PATCH 8/15] arm: Introduce multilibs for PACBTI target feature
This patch add the following new multilibs.
thumb/v8.1-m.main+pacbti/mbranch-protection/nofp
thumb/v8.1-m.main+pacbti+dp/mbranch-protection/soft
thumb/v8.1-m.main+pacbti+dp/mbranch-protection/hard
thumb/v8.1-m.main+pacbti+fp/mbranch-protection/soft
thumb/v8.1-m.main+pacbti+fp/mbranch-protection/hard
thumb/v8.1-m.main+pacbti+mve/mbranch-protection/hard
Triggering the following compiler flags:
-mthumb -march=armv8.1-m.main+pacbti -mbranch-protection=standard -mfloat-abi=soft
-mthumb -march=armv8.1-m.main+pacbti+fp -mbranch-protection=standard -mfloat-abi=softfp
-mthumb -march=armv8.1-m.main+pacbti+fp -mbranch-protection=standard -mfloat-abi=hard
-mthumb -march=armv8.1-m.main+pacbti+fp.dp -mbranch-protection=standard -mfloat-abi=softfp
-mthumb -march=armv8.1-m.main+pacbti+fp.dp -mbranch-protection=standard -mfloat-abi=hard
-mthumb -march=armv8.1-m.main+pacbti+mve -mbranch-protection=standard -mfloat-abi=hard
gcc/
* config/arm/t-rmprofile: Add multilib rules for march +pacbti and
mbranch-protection.
gcc/testsuite/
* gcc.target/arm/multilib.exp: Add pacbti related entries.
