RUSTFLAGS="-Z autodiff=Enable,PrintModbefore" cargo +enzyme build --release &> out.ll
RUSTFLAGS="-Z autodiff=Enable,PrintModBefore" cargo +enzyme build --release &> out.ll
```
This also captures a few warnings and info messages above and below your module. open out.ll and remove every line above `; moduleid = <somehash>`. Now look at the end of the file and remove everything that's not part of llvm-ir, i.e. remove errors and warnings. The last line of your llvm-ir should now start with `!<somenumber> = `, i.e. `!40831 = !{i32 0, i32 1037508, i32 1037538, i32 1037559}` or `!43760 = !dilocation(line: 297, column: 5, scope: !43746)`.
