Reviewers: Benedikt Meurer,
Message:
In the current state of the CL, the Intel platforms use code with branches,
while the ARM platforms use branch-free code. I have the slight feeling that
using branches on ARM/A64 will be better, too, because the platform ports
would
be more similar then and the branch-free code is quite a brain-teaser and
hard
to understand and maintain. WDYT?
Description:
Implement flooring division by a constant via truncating division by a
constant.
