Bug ID: 40123
Summary: [X86] Missing cost model for saturating add/sub
intrinsics
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86
Assignee: unassignedb...@nondot.org
Reporter: nikita....@gmail.com
CC: craig.top...@gmail.com, llvm-bugs@lists.llvm.org,

We currently don't have cost modelling for uadd_sat, sadd_sat, usub_sat and
ssub_sat intrinsics (and they need to be marked as trivially vectorizable). I
think this is the last blocker before we can start canonicalizing in
InstCombine.
