Hello, I am trying to isolate an assertion failure in if-converter (on PPC) and I generated a textual debuglog with: ``` LLVM_ARGS=-print-before-all -print-module-scope -filter-print-funcs=japi1__require_7687 ``` and after splicing out the the MIR before the if-converter pass I would like to run `llc -march=ppc64le -run-pass=if-converter input.mir` so that I can start minimising the MIR. This steps fails for me with a: ``` error: YAML:188:20: Unrecognized character while tokenizing. Function Live Ins:...

Hello Valentin, To generate a mir test case i think the process is to first create an IR file by passing '-S -emit-llvm' to clang, then you can feed that file into llc and use stop-before to get the mir just before the if-converter pass, eg: `llc -stop-before=if-converter -simplify-mir -o test.mir test.ll`. Also there is a MIR language reference: https://llvm.org/docs/MIRLangRef.html
