About
GCC does a fairly poor job at generating efficient code for various saturating arithmetic idioms. Additionally almost no support for vectorized saturating arithmetic is in place. This gap will show up in coremark pro and possibly spec2k6. Followup items may include:
- Making sure generated code is amenable to zicond when possible
- Moving some of the target specific expansions into generic code
