The temp.mlir is attached here. I was planed to reduce the file through mlir-reduce, however, mlir-reduce crashed. The detail please refered to this issue
You seem to be using an old version of MLIR (your .mlir file can't be parsed right now because it predates the split of the func dialect).
Do you have a way to reproduce this at HEAD?
You seem to be using an old version of MLIR (your .mlir file can't be parsed right now because it predates the split of the func dialect).
Yeah, I built mlir from the source code of tag llvmorg-14.0.6. I'll try to reproduce it at HEAD.
yes, it can be reproduced at HEAD. The new mlir file generated with HEAD version still crashed with largely the same crash traces:

Which revision did you use? (your IR file has an op that was renamed on 10/4).
The latest commit in the log is .
commit 7b7d3b20ffec9f0af0534178117a7e0c250f6a79 (origin/main, origin/HEAD) Author: Nikita Popov [email protected] Date: Tue Oct 11 09:53:08 2022 +0200
[AsmParser] Remove some redundant checks for align attributes
The verifier already has a more general check that the attribute is
legal for the position it is used in.
BTW, what does 'renamed' mean?
Updated for current HEAD: temp_head.mlir.txt
For your provided file, some op is unknown.
error: custom op 'tensor.empty' is unknown
%0 = tensor.empty() : tensor<4xf32>
I was referring to https://github.com/llvm/llvm-project/commit/81ca5aa452400843235e058bc9c83fe71eccd593
You likely built before this commit (I updated your file to make it work past it)
This pass is written in a way that does not support tensor types, it has this helper:
/// Create an integer or index constant.
static Value createConst(Location loc, Type type, int value,
PatternRewriter &rewriter) {
return rewriter.create<arith::ConstantOp>(
loc, rewriter.getIntegerAttr(type, value));
}
Here it assumes everything can be a scalar.
I'm hesitant to try to fix this because the current wisdom seems to deprecate the support of tensors in the arith dialect entirely.
I see, so the operation like %601 = arith.maxsi %103, %284 : tensor<4x4xi32> is also not supported at HEAD? Because now I rerun --arith-expand on your provided file. This time it crashes with largely the same crash info instead of unknown tensor.empty op.
Updated for current HEAD: temp_head.mlir.txt
This file does not crash anymore on current main (17a58b3ca7ec1) with mlir-opt --arith-expand temp_head.mlir.txt nor mlir-opt temp_head.mlir.txt.
I'll close this issue. Feel free to reopen if necessary.
