Hi all,
The second scan-assembler test for clz\tv\[0-9\]+\.2s FAILs on this test
due to vector costs on A57.
The vectorisation happens for cortex-a53 and thunderx.
I think this test was supposed to test the capability of vectorising clz
rather than the tuning decision of whether to (though I imagine people
can argue the other way),
so this patch adds an -fno-vect-cost-model to it to get it to always
vectorise.
This way the test passes on all -mcpu options.
Ok for trunk?
Thanks,
Kyrill
