aarch64: fix unwinding in longjmp
|
|
|
|
Previously, longjmp() on aarch64 was using CFI directives around the
|
|
call to __libc_arm_za_disable() after CFA was redefined at the start
|
|
of longjmp(). This may result in unwinding issues. Move the call and
|
|
surrounding CFI directives to the beginning of longjmp().
