Topic: Inspecting generated code

Hello,

I'm wondering if there's an easy way to inspect the code generated during compilation, e.g., the LLVM IR. Does this require using a custom roc compiler build? My use case is to be able to understand whether two possible algorithm implementations would result in a functionally identical executable.

Thanks!

--debug will dump llvm ir

It can be quite verbose and hard to follow

Brendan Hansknecht (May 09 2023 at 16:01):

Also, it requires a tool called debugir if you want more debug info and compilation to finish.

Brendan Hansknecht (May 09 2023 at 16:02):

But you will get a raw dump even without the tool

Sounds like enough to get me started. Thanks!

Also, feel free to ask direct questions here, we may already know the answers to some of your optimization related questions. Of course, won't be as exact as running the llvm optimization and comparing, but it should be pretty close.
