[FFmpeg-devel] [PATCH] checkasm: Test whether direct cycle counter access works

This should print a nicer error message than crashing due to an illegal instruction, if direct cycle counter access isn't allowed. This matches the dav1d checkasm commit 95a192549a448b70d9542e840c4e34b60d09b093. --- tests/checkasm/checkasm.c | 12 +++- 1 file changed, 11 insertions(+), 1
