Summary

Since CLZ is not available for Thumb1, we use __ARM_ARCH_ISA_THUMB != 1 as one of the conditions.

weimingz retitled this revision from to [builtin] for the condition for check __ARM_FEATURE_CLZ.

weimingz updated this object.

weimingz added reviewers: rnk, compnerd.

Right, this looks correct.

I ran clang format, but uploaded the old version. :(

This revision was automatically updated to reflect the committed changes.

Thanks!
