Git commit 70cfbd56b66a4a61cb71daff1b5029a8bad03ef8 by Jon Roelofs (on behalf of Francis Visoiu Mistrih) on 22/07/2026 at 22:25..
[Matrix] Add remarks for matrix loads and stores

Emit remarks for loads and stores over 128B (configurable via
-memop-remark-size-threshold). Also emit remarks for each step in
the inlining chain so callers can be identified.

Git commit 52a6c35cd9cef3ac987e30961a135fd3f2101161 by Jon Roelofs (on behalf of Francis Visoiu Mistrih) on 23/07/2026 at 00:17..
[Matrix] Split TileSize into per-dimension fields; add remainder loop infrastructure

Split the single TileSize field in TileInfo into TileNumRows,
TileNumInner, and TileNumColumns to enable non-square tiles.

Add CreateTiledLoopsWithRemainder() which generates a full loop
nest covering remainder rows and columns that don't evenly divide
the tile size.

Expose asIndex()/indexType() helpers from MatrixUtils.cpp for use
by callers building the tiled loop bodies.

In LowerMatrixIntrinsics, replace the old TileSize/TileLoopsThreshold
cl::opts with per-dimension TileSizeRows/Inner/Columns and add
TileUseLoops (default false) as the explicit opt-in for loop-based
tiling. Add isTilingLoopProfitable() to gate when loops are
worthwhile vs. inlining the tile computation.

Git commit e278418a70c481adf47a9a94ee2b5e4c4d86bbcf by Jon Roelofs (on behalf of Francis Visoiu Mistrih) on 23/07/2026 at 01:01..
[Matrix] Add/remove transposes to row vectors to see them as column vectors

In column-major, add or remove transposes to row vectors in order to see
them as column vector during the rest of the lowering.
