Relaying here the review comment : #755 (comment) (@jtuyls )
Two reasons :-
- The second argument to
SmallVector<arg1, arg2>used to be mandatory but stopped being so - I came across this relaxed constraint in one of the upstream contribution's review comments. - In case of "splitting" we start creation of a new L2 logicalobjectFifo via L2->L1's route. In case of "combing" we start it from L3->L2. The function
createNewLogicalObjectFifodeclaration complains because :-
a.SmallVector<arg1>!=SmallVector<arg1, 4>
b.SmallVector<arg1, 4>!=SmallVector<arg1, 6>
Therefore the only way to circumvent point 2z, that I knew of, was to remove this which aligned well with point 1.

I think it's still useful to specify the number of inlined elements in the vector as we know it will usually be less than 4 and not much more: SmallVector<OpFoldResult, 4>. createNewLogicalObjectFifo then has to accept a SmallVectorImpl instead of a SmallVector to avoid the issue in 2).

Sure, I've addressed it in the latest push. Please take a look.

Hi @jtuyls , based on #755 (review) I'm segregating #755 into two PRs. This concerns NFC changes required to have the actual pass (#760) implemented. |
