mydeveloperday 3c8666ef9a [clang-format] NFC update LLVM overall clang-formatted status
Whilst the % clang-formatted remains the same, the number
of files added to the LLVM project has risen by almost by 259.

- 190 of them have been added clang-format clean.
- 69 files have been added unformatted. (lit tests should be excluded from this number)

- 291 files have been added to the list of files that are clang-format clean
- 101 files have either become unclean or have been removed

As this updates the clang-formatted-files there are now
8139 files that are clean which we can be used as a regression test when making changes to clang-format.

Amy Kwan 150681f2f3 [PowerPC] Prevent the optimizer from producing wide vector types in IR.
This patch prevents the optimizer from producing wide vectors in the IR,
specifically the MMA types (v256i1, v512i1). The idea is that on Power, we only
want to be producing these types only if the vector_pair and vector_quad types
are used specifically.

To prevent the optimizer from producing these types in the IR,
vectorCostAdjustmentFactor() is updated to return an instruction cost factor or
an invalid instruction cost if the current type is that of an MMA type. An
invalid instruction cost returned by this function signifies to other cost
computing functions to return the maximum instruction cost to inform the
optimizer that producing these types within the IR is expensive, and should not
be produced in the first place.

This issue was first seen in the test case included within this patch.

unsigned long, while ptrdiff_t is just int. Hence, std::ssize_t ends up
being long, which is not the same as ptrdiff_t. This is usually not an

seongwon bang 35c1e6ac1a [MLIR] [docs] Fix misguided examples in memref.subview operation.
The examples in `memref.subview` operation are misguided in that subview's strides operands mean "memref-rank number of strides that compose multiplicatively with the base memref strides in each dimension.".
So the below examples should be changed from `Strides: [64, 4, 1]` to `Strides: [1, 1, 1]`

Before changes
```
// Subview with constant offsets, sizes and strides.
%1 = memref.subview %0[0, 2, 0][4, 4, 4][64, 4, 1]
  : memref<8x16x4xf32, (d0, d1, d2) -> (d0 * 64 + d1 * 4 + d2)> to
    memref<4x4x4xf32, (d0, d1, d2) -> (d0 * 64 + d1 * 4 + d2 + 8)>
```

After changes
```
// Subview with constant offsets, sizes and strides.
%1 = memref.subview %0[0, 2, 0][4, 4, 4][1, 1, 1]
  : memref<8x16x4xf32, (d0, d1, d2) -> (d0 * 64 + d1 * 4 + d2)> to
    memref<4x4x4xf32, (d0, d1, d2) -> (d0 * 64 + d1 * 4 + d2 + 8)>
```

Also I fixed some syntax issues in docs related with memref layout map and added detailed explanation in subview rank reducing case.

Pavel Labath 165545c7a4 [lldb/gdb-remote] Ignore spurious ACK packets
Although I cannot find any mention of this in the specification, both
gdb and lldb agree on sending an initial + packet after establishing the
connection.

OTOH, gdbserver and lldb-server behavior is subtly different. While
lldb-server *expects* the initial ack, and drops the connection if it is
not received, gdbserver will just ignore a spurious ack at _any_ point
in the connection.

This patch changes lldb's behavior to match that of gdb. An ACK packet
is ignored at any point in the connection (except when expecting an ACK
packet, of course). This is inline with the "be strict in what you
generate, and lenient in what you accept" philosophy, and also enables
us to remove some special cases from the server code. I've extended the
same handling to NAK (-) packets, mainly because I don't see a reason to
treat them differently here.

(The background here is that we had a stub which was sending spurious
+ packets. This bug has since been fixed, but I think this change makes
sense nonetheless.)

Pavel Labath a6fedbf20c [lldb/gdb-remote] Remove initial pipe-draining workaround
This code, added in rL197579 (Dec 2013) is supposed to work around what
was presumably a qemu bug, where it would send unsolicited stop-reply
packets after the initial connection.

At present, qemu does not exhibit such behavior. Also, the 10ms delay
introduced by this code is sufficient to mask bugs in other stubs, but
it is not sufficient to *reliably* mask those bugs. This resulted in
flakyness in one of our stubs, which was (incorrectly) sending a +
packet at the start of the connection, resulting in a small-but-annoying
number of dropped connections.

Simon Pilgrim 63b1e58f07 [DAG] SimplifyDemandedBits - simplify rotl/rotr to shl/srl (REAPPLIED)
If we only demand bits from one half of a rotation pattern, see if we can simplify to a logical shift.

For the ARM/AArch64 rev16/32 patterns, I had to drop a fold to prevent srl(bswap()) -> rotr(bswap) -> srl(bswap) infinite loops. I've replaced this with an isel PatFrag which should do the same task.

Reapplied with fix for AArch64 rev patterns to matching the ARM fix.

mydeveloperday c94667a810 [clang-format] [PR52595] clang-format does not recognize rvalue references to array
https://bugs.llvm.org/show_bug.cgi?id=52595

missing space between `T(&&)` but not between `T (&` due to && being incorrectly thought of as `UnaryOperator`  rather than `PointerOrReference`

```
int operator()(T (&)[N]) { return 0; }
int operator()(T(&&)[N]) { return 1; }
```

Existing Unit tests are changed because actually I think they are originally incorrect, and are inconsistent with the (&) cases that are 4 or 5 lines above them.

Tobias Gysi 4b03906346 [mlir][linalg] Perform checks early in hoist padding.
Instead of checking for unexpected operations (any operation with a region except for scf::For and `padTensorOp` or operations with a memory effect) while cloning the packing loop nest perform the checks early. Update `dropNonIndexDependencies` to check for unexpected operations. Additionally, check all of these operations have index type operands only.

Tobias Gysi fd723eaa92 [mlir][linalg] Limit hoist padding to constant paddings.

Tobias Gysi ed7c1fb9b0 [mlir][linalg] Add backward slice filtering in hoist padding.
Adapt hoist padding to filter the backward slice before cloning the packing loop nest. The filtering removes all operations that are not used to index the hoisted pad tensor op and its extract slice op. The filtering is needed to support the more complex loop nests created after fusion. For example, fusing the producer of an output operand can added linalg ops and pad tensor ops to the backward slice. These operations have regions and currently prevent hoisting.

The following example demonstrates the effect of the newly introduced `dropNonIndexDependencies` method that filters the backward slice:
```
%source = linalg.fill(%cst, %arg0)
scf.for %i
  %unrelated = linalg.fill(%cst, %arg1)    // not used to index %source!
  scf.for %j (%arg2 = %unrelated)
    scf.for %k                             // not used to index %source!
      %ubi = affine.min #map(%i)
      %ubj = affine.min #map(%j)
      %slice = tensor.extract_slice %source [%i, %j] [%ubi, %ubj]
      %padded_slice = linalg.pad_tensor %slice
```
dropNonIndexDependencies(%padded_slice, %slice)
removes [scf.for %k, linalg.fill(%cst, %arg1)] from backwardSlice.

clangd uses Decl::isFunctionOrFunctionTemplate to check if the decl given in a prepareCallHierarchy request is eligible for prepareCallHierarchy. We change to use isFunctionOrMethod which includes functions and ObjC methods.

David Green 3a700cabdc [SDAG] Allow Unknown sizes when refining MMO alignments. NFC
The changes in D113888 / 32b6c17b29 altered the memory size of a
masked store, as it will store an unknown number of bytes not the full
vector size. We can have situations where the masked stores is legalized
and then turned to a normal store, as the mask is known to be all ones.
This creates a store with an unknown size MMO that was hitting this
assert.

The store created can be given a better size in a followup patch. This
currently adjusts the assert to handle unknown sizes.
