[mlir][bufferize] Fix tensor copy insertion for dynamic tensors

TensorCopyInsertion inserts bufferization.alloc_tensor ops in case of RaW conflicts. If such a tensor is dynamically shaped, tensor.dim ops are inserted. There is an optimization for ops such as tensor.extract_slice: A copy of the result is created instead of the operand. Afterwards, all uses of the result are updated. E.g.:

```
%0 = tensor.extract_slice ... : tensor<?xf32> to tensor<?xf32>
%1 = tensor.dim %0, %c0 : tensor<?xf32>
%2 = bufferization.alloc_tensor(%dim) : tensor<?xf32>
```

All uses of %0, except for tensor.dim and bufferization.alloc_tensor (if any), should be replaced. Before this change, the use in tensor.dim was also replaced, resulting in IR that had a dominance error.

Note: There is no test case for this fix because the bug cannot be triggered with tensor.extract_slice, which implements an interface to reify result shapes. This bug appeared in an external project with a tensor.extract_slice-like op that does not implement that interface, in which case tensor.dim ops must be created. We do not have such an op in MLIR to trigger this bug.

Max Kazantsev [Wed, 21 Dec 2022 05:47:36 +0000 (12:47 +0700)]
[SCEV] Help getLoopInvariantExitCondDuringFirstIterations deal with complex `umin` exit counts. PR59615

Recent improvements in symbolic exit count computation revealed some problems with
SCEV's ability to find invariant predicate during first iterations. Ultimately it is based on its
ability to prove some facts for value on the last iteration. This last value, when it includes
`umin` as part of exit count, isn't always simplified enough. The motivating example is following:

https://github.com/llvm/llvm-project/issues/59615

Could not prove:
```
        Pred = 36, LHS = (-1 + (-1 * (2147483645 umin (-1 + %var)<nsw>))<nsw> + %var), RHS = %var
        FoundPred = 36, FoundLHS = {1,+,1}<nuw><nsw><%bb3>, FoundRHS = %var
```
Can prove:
```
        Pred = 36, LHS = (-1 + (-1 * (-1 + %var)<nsw>)<nsw> + %var), RHS = %var
        FoundPred = 36, FoundLHS = {1,+,1}<nuw><nsw><%bb3>, FoundRHS = %var
```

Here ` (2147483645 umin (-1 + %var)<nsw>)` is exit count composed of two parts from
two different exits: `2147483645 ` and `(-1 + %var)<nsw>`. When it was only one (latter)
analyzeable exit, for it everything was easily provable. Unfortunately, in general case `umin`
in one of `add`'s operands doesn't guarantee that the whole sum reduces, especially in presence
of negative steps and lack of `nuw`. I don't think there is a generic legal way to somehow play
around this `umin`.

So the ad-hoc solution is following: if we failed to find an equivalent predicate that is invariant
during first `MaxIter` iterations, and `MaxIter = umin(a, b, c...)`, try to find solution for at least one
of `a`, `b`, `c`... Because they all are `uge` than `MaxIter`, whatever is true during `a (b, c)` iterations
is also true during `MaxIter` iterations.

- v4T Thumb long branches needed their own thunk. We could have used the v6M

  MOVV/MOVT, which wasn't available yet for v4T.
- Remove the `lack of BLX' warning. LLVM only supports Arm Architecture versions
  upwards of v4, which we now all support in LLD.
- renamed existing thunks to better reflect their use:

  ARMV5PILongThunk -> ARMV4PILongThunk
- removed isCompatibleWith method from ARMV5ABSLongThunk and ARMV5PILongThunk,

Support for (efficient) position independent thunks for v4T will be added in a

cleanup.

This partially reverts 968e2e7b3db1 (svn r62356) which claimed:

  CreateVirtualRegisters does trivial copy coalescing. If a node def is

  the CopyToReg. This won't work for SDNode that is a clone or is itself
  cloned. Disable this optimization for those nodes or it can end up
  with non-SSA machine instructions.

This is true for CreateVirtualRegisters but r62356 also updated
EmitCopyFromReg where it is not true. Firstly EmitCopyFromReg only
coalesces physical register copies, so the concern about SSA form does
not apply. Secondly making the loop over users in EmitCopyFromReg
conditional on `!IsClone && !IsCloned` breaks the handling of cloned
nodes, because it leaves MatchReg set to true by default, so it assumes
that all users will copy the defined value back to the same physical

[mlir] Add RuntimeVerifiableOpInterface and transform

Static op verification cannot detect cases where an op is valid at compile time but may be invalid at runtime.

An example of such an op is `memref::ExpandShapeOp`.

Invalid at compile time: `memref.expand_shape %m [[0, 1]] : memref<11xf32> into memref<2x5xf32>`

Valid at compile time (because we do not know any better): `memref.expand_shape %m [[0, 1]] : memref<?xf32> into memref<?x5xf32>`. This op may or may not be valid at runtime depending on the runtime shape of `%m`.

Invalid runtime ops such as the one above are hard to debug because they can crash the program execution at a seemingly unrelated position or (even worse) compute an invalid result without crashing.

This revision adds a new op interface `RuntimeVerifiableOpInterface` that can be implemented by ops that provide additional runtime verification. Such runtime verification can be computationally expensive, so it is only generated on an opt-in basis by running `-generate-runtime-verification`. A simple runtime verifier for `memref::ExpandShapeOp` is provided as an example.

Louis Dionne [Tue, 20 Dec 2022 23:04:53 +0000 (18:04 -0500)]
[clang] Re-apply change to avoid passing -stdlib=libc++ spuriously to CC1 on Darwin

Previously, we would be passing down -stdlib=libc++ from the Driver
to CC1 whenever the default standard library on the platform was libc++,
even if -stdlib= had not been passed to the Driver. This meant that we
would pass -stdlib=libc++ in nonsensical circumstances, such as when
compiling C code.

This logic had been added in b534ce46bd40 to make sure that header
search paths were set up properly. However, since libc++ is now the
default Standard Library on Darwin, passing this explicitly is not
required anymore. Indeed, if no -stdlib= is specified, CC1 will end
up using libc++ if it queries which standard library to use, without
having to be told.

Not passing -stdlib= at all to CC1 on Darwin should become possible
once CC1 stops relying on it to set up framework search paths.

Furthermore, this commit also removes a diagnostic checking whether the
deployment target is too old to support libc++. Nowadays, all supported
deployment targets use libc++ and compiling with libstdc++ is not
supported anymore. The Driver was the wrong place to issue this
diagnostic since it doesn't know whether libc++ will actually be linked
against (e.g. C vs C++), which would lead to spurious diagnostics.
Given that these targets are not supported anymore, we simply drop
the diagnostic instead of trying to refactor it into CC1.

This is a re-application of 6540f32db09c which had been reverted in
49dd02bd0819 because it broke a compiler-rt test. The test had broken
because we were compiling C code and passing -stdlib=libc++, which Clang
will now warn about.

[dsymutil] Track uncloned references in the DIEInfo.

To improve deduplication across CUs within a single object file,
2b747241a6a0 changed the way we track ODR canonical candidates. The
result is that some assumptions no longer hold. Because of the
aforementioned change, the following condition

  assert(Ref > InputDIE.getOffset());

in DWARFLinker::DIECloner::cloneDieReferenceAttribute is no longer an
invariant. An example of a situation where this assertion no longer
holds is when we have decided to replace a backward reference in the
current CU with a forward reference in a subsequent CU. The ODR
canonical DIE hasn't been emitted yet, but the references DIE has an
offset smaller than the current DIE. The assertion is only true if the
referenced DIE was the ODR canonical DIE, which is no longer guaranteed
to be part of the same CU.

Big thanks to Alexey for putting a test together.

[BuildLibCalls][RISCV] Sign extend return value of bcmp on riscv64.

riscv64 wants callees to sign extend signed and unsigned int returns.

The caller can use this to avoid a sign extend if the result is
used by a comparison since riscv64 only has 64-bit compares.

InstCombine/SimplifyLibCalls aggressively turn memcmps that are only
used by an icmp eq 0 into bcmp, but we lose the signext attribute that
would have been present on the memcmp. This causes an unneeded sext.w
in the generated assembly.

This looks even sillier if bcmp is implemented alias to memcmp. In
that case, not only did we not get any savings by using bcmp, we added
an instruction.

This probably applies to other functions, this just happens to be
the one I noticed so far.

Checking for NVIDIA GPUs will be done later as this is a little

it will soon be deprecated, the replacement requires a newer CMake
