> Tests for `int_hr_t` (`short fract`) don't seem to work as it's just a `typedef` for `signed char`, and we don't have defined tests for that (and also `signed char` != `char`), I’ve excluded the tests for this type from `libc/test/CMakeLists.txt` for now. Apart from that, I built on the implementations of the already existing `fxbits` and `countlsfx` functions for this patch.

What's the failure you're seeing for `short fract`?
