> i386: Implement .SAT_ADD for unsigned scalar integers [PR112600]
The target implementation of .SAT_ADD is fairly simple, but the newly added
usadd{m}3 optab enables middle-end transformations to saturating add - you will
notice .SAT_ADD operation in _.265t.optimized dump.
My bet is on the middle-end transforming to .SAT_ADD in a wrong way. CC added.
