Hi,
I am using yocto to build and run ARM64 toolchain(SDK)
GCC was configured with the "--enable-standard-branch-protection" flag for
arm64.
It was having better performance while running some benchmarks.
However, it resulted in many regressions as it has been generating bti
instruction.
Testcases expecting specific assembly are failing.
Can you please let us know whether it's valid to configure arm64 with the "
--enable-standard-branch-protection" flag?
Regards,
Yash.
