Hi,
This patch adds the support for pacbti multlilib linking by making
"-mbranch-protection=none" as default multilib option for arm-none-eabi
target.
Eg 1.
If the passed command line flags are (without mbranch-protection):
a) -march=armv8.1-m.main+mve -mfloat-abi=hard -mfpu=auto
"-mbranch-protection=none" will be used in the multilib matching.
Eg 2.
If the passed command line flags are (with mbranch-protection):
a) -march=armv8.1-m.main+mve+pacbti -mfloat-abi=hard -mfpu=auto -mbranch-protection=pac-ret
"-mbranch-protection=standard" will be used in the multilib matching.
Regression tested on arm-none-eabi and bootstrapped on arm-none-linux-gnueabihf.
Ok for master?
Regards,
Srinath.
