Hello, I crashed LLVM, and it asked me to submit a bug, so here it is:

> llvm-spirv "cache/0c2c3f7472583358/bc/solver.bc" -o "cache/0c2c3f7472583358/spv/solver.spv"

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

The code that was being compiled is 12,000 lines long, IDK if you want me to post that as well.

The crash in question is in the LLVM SPIR-V translator tool, located at https://github.com/KhronosGroup/SPIRV-LLVM-Translator, not in llvm itself.

As for tests, it's not really actionable without the original source code. You can run it through creduce to get a much smaller file for reproducing the same failure.
