This property is explicitly for use only in the interactive editor,
and NOT in commands. It's use worked until we got more careful about
not leaving lldb.target lying around in the script interpreter.
I also added a quick sniff test for the save_crashlog command.

While LazyBlockFrequencyInfo itself is lazy, the dominator tree
and loop info analyses it requires are not. Drop the dependency
on this pass in SelectionDAGIsel at O0.
This makes for a ~0.6% O0 compile-time improvement.

Summary: The following code from
/llvm/lib/Transforms/Utils/LoopUnrollAndJam.cpp can be used by other
transformations:
while (!MergeBlocks.empty()) {
BasicBlock *BB = *MergeBlocks.begin();
BranchInst *Term = dyn_cast<BranchInst>(BB->getTerminator());
if (Term && Term->isUnconditional() &&
L->contains(Term->getSuccessor(0))) {
BasicBlock *Dest = Term->getSuccessor(0);
BasicBlock *Fold = Dest->getUniquePredecessor();
if (MergeBlockIntoPredecessor(Dest, &DTU, LI)) {
// Don't remove BB and add Fold as they are the same BB
assert(Fold == BB);
(void)Fold;
MergeBlocks.erase(Dest);
} else
MergeBlocks.erase(BB);
} else
MergeBlocks.erase(BB);
}
Hence it should be separated into its own utility function.

Summary:
PHIs result register class is set to VGPR or SGPR depending on the cross block value divergence.
In some cases uniform PHI need to be converted to return VGPR to prevent the oddnumber of moves values from VGPR to SGPR and back.
PHI should certainly return VGPR if it has at least one VGPR input. This change adds the exception.
We don't want to convert uniform PHI to VGPRs in case the only VGPR input is a VGPR to SGPR COPY and definition od the
source VGPR in this COPY is move immediate.

This allows constructing operand adaptor from existing op (useful for commonalizing verification as I want to do in a follow up).
I also add ability to use member initializers for the generated adaptor constructors for convenience.
Differential Revision: https://reviews.llvm.org/D80667
Summary:
WrapperMatcherInterface is an abstraction over a member variable -- in
other words, not much of an abstraction at all. I think it makes code
harder to read more than in helps with deduplication. Not to even
mention the questionable usage of the ~Interface suffix for a type with
state.

Summary:
New logic tries to narrow possible result values of the remainder operation
based on its operands and their ranges. It also tries to be conservative
with negative operands because according to the standard the sign of
the result is implementation-defined.

Differential Revision: https://reviews.llvm.org/D80117
Summary:
Previously the current solver started reasoning about bitwise AND
expressions only when one of the operands is a constant. However,
very similar logic could be applied to ranges. This commit addresses
this shortcoming. Additionally, it refines how we deal with negative
operands.

Differential Revision: https://reviews.llvm.org/D79336
Summary:
This change introduces a new component to unite all of the reasoning
we have about operations on ranges in the analyzer's solver.
In many cases, we might conclude that the range for a symbolic operation
is much more narrow than the type implies. While reasoning about
runtime conditions (especially in loops), we need to support more and
more of those little pieces of logic. The new component mostly plays
a role of an organizer for those, and allows us to focus on the actual
reasoning about ranges and not dispatching manually on the types of the
nested symbolic expressions.

Summary:
SymIntExpr, IntSymExpr, and SymSymExpr share a big portion of logic

`RewriteRule`'s `applyFirst` was brittle with respect to the default setting of the

rewrite rules so that they are insensitive to any changes in defaults.

Make ConvertKernelFuncToCubin pass to be generic:
- Rename to ConvertKernelFuncToBlob.
- Allow specifying triple, target chip, target features.
- Initializing LLVM backend is supplied by a callback function.
- Lowering process from MLIR module to LLVM module is via another callback.
- Change mlir-cuda-runner to adopt the revised pass.
- Add new tests for lowering to ROCm HSA code object (HSACO).
- Tests for CUDA and ROCm are kept in separate directories.

This one is slightly odd since it counts as an address expression,
which previously could never fail. Allow the existing TTI hook to
return the value to use, and re-use it for handling how to handle
ptrmask.
Handles the no-op addrspacecasts for AMDGPU. We could probably do
something better based on analysis of the mask value based on the
address space, but leave that for now.
Add the two conversion operations `index_to_size` and `size_to_index` to the
shape dialect.
This facilitates the conversion of index types between the shape and the
standard dialect.

For example on X86 linux =>

on X86 Windows-gnu =>
DW_AT_location (DW_OP_fbreg +112, DW_OP_deref, DW_OP_lit4, DW_OP_mul)
: error: CHECK-SAME: expected string not found in input
; CHECK-SAME: DW_OP_plus_uconst 0x70, DW_OP_deref, DW_OP_lit4, DW_OP_mul
