…-phi operand fix. (llvm#121744) This relands the reverted llvm#120721 with a fix for cases where neither reduction operand are the reduction phi. Only 6311423 and 6311423 are new on top of the reverted PR. --------- Co-authored-by: Nicholas Guy <[email protected]> (cherry-picked from 795e35a)
This patch introduces lowering of the partial add reduction intrinsic to a udot or svdot for AArch64. This also involves adding a `shouldExpandPartialReductionIntrinsic` target hook, which AArch64 will return false from in the cases that it can be lowered.
…ct (llvm#107078) This PR adds lowering for fixed-width <4 x i32> and <2 x i32> partial reductions to a dot product when Neon and the dot product feature are available. The work is by Max Beck-Jones (@DevM-uk).
