There a two passes that fail when running with `DLLVM_ENABLE_EXPENSIVE_CHECKS`. Namely:
- Scalarize vector operations
- DXIL Resource Access
They fail with the slight variations of the following:
```
Pass modifies its input and doesn't report it: DXIL Resource Access
Pass modifies its input and doesn't report it
UNREACHABLE executed at llvm-project/llvm/lib/IR/LegacyPassManager.cpp:1405!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
Stack dump:
0. Program arguments: llvm-project/build/bin/opt -S -dxil-resource-access llvm-project/llvm/test/CodeGen/DirectX/ResourceAccess/load_typedbuffer.ll
1. Running pass 'Function Pass Manager' on module 'llvm-project/llvm/test/CodeGen/DirectX/ResourceAccess/load_typedbuffer.ll'.
2. Running pass 'DXIL Resource Access' on function '@load_float4'
```
To reproduce, build main with `DLLVM_ENABLE_EXPENSIVE_CHECKS=ON`.
