Paul Walker	eae26b6640	[IRBuilder] Use canonical i64 type for insertelement index used by vector splats. Instcombine prefers this canonical form (see getPreferredVectorIndex), as does IRBuilder when passing the index as an integer so we may as well use the prefered form from creation. NOTE: All test changes are mechanical with nothing else expected beyond a change of index type from i32 to i64. Differential Revision: https://reviews.llvm.org/D140983	2023-01-11 14:08:06 +00:00
Florian Hahn	ed2fdace89	[LV] Use separate index to access StoredValues in vectorizeInterleave. StoredValues only has entries for members of the interleave group. If there are gaps, then using the index i here will either access a wrong entry or be out-of-bounds. Instead use a dedicated index that only gets incremented for members of the interleave group. Fixes #59090.	2022-11-25 15:28:05 +00:00

[IRBuilder] Use canonical i64 type for insertelement index used by vector splats.

Instcombine prefers this canonical form (see getPreferredVectorIndex),
as does IRBuilder when passing the index as an integer so we may as
well use the prefered form from creation.

NOTE: All test changes are mechanical with nothing else expected
beyond a change of index type from i32 to i64.

[LV] Use separate index to access StoredValues in vectorizeInterleave.

StoredValues only has entries for members of the interleave group. If
there are gaps, then using the index i here will either access a wrong
entry or be out-of-bounds.

the interleave group.

Fixes #59090.
