Git commit 7609cb83bf5fc5c25e287770db277dbb34e674b8 by GitHub (on behalf of Finn Plummer) on 04/08/2026 at 17:33..
[DirectX] Prevent `dxil-resource-access` from inserting a resource access in-between phi nodes (#211343)

The pass can incorrectly place a load/store within the phi nodes at top
of the basic block: https://godbolt.org/z/x5Ec4GWGT

This is resolved by updating `replaceHandleWithIndices` to adjust the
insertion point when the ptr comes from a phi node.

Resolves, in part, https://github.com/llvm/llvm-project/issues/211121

Git commit 5382f7d64ff59d198091ffd263d7adecf5d7dd5a by GitHub (on behalf of Benjamin Maxwell) on 04/08/2026 at 17:48..
[CostModel][AArch64] Add initial costs for `masked.compressstore` (#213712)

This adds an initial cost model for `masked.compressstore`. The tests
are based on `masked_expand_load.ll`, which covers all configurations
for the `expand`/`compact` instructions.

Note: Right now, we only report valid costs for `masked.compressstore`
operations that can be lowered with SVE1 (as that's all we handle ISEL
for at the moment).
