Subject: [Qemu-devel] [PATCH 00/11] target/arm: Implement ARMv8.5-BTI
Date: Thu, 10 Jan 2019 23:17:25 +1100 [thread overview]
Message-ID: <20190110121736.23448-1-richard.henderson@linaro.org> (raw)
The branch target identification extension does not yet have
kernel or gcc support. It should be in shape for developing
those though.
In system mode I do honor the GP bit from the page tables.
In user-only mode, there is a way to pretend that the GP bit
is always set. Further linux-user changes will have to track
the ABI that gets developed.
In the meantime, provide a statically linable make check-tcg
test for the functionality.
