Keep Optimization Remark Yaml in NewPM

Authored by lenary on Aug 18 2017, 5:21 PM.



The New Pass Manager infrastructure was forgetting to keep around the optimization remark yaml file that the compiler might have been producing. This meant setting the option to '-' for stdout worked, but setting it to a filename didn't give file output (presumably it was deleted because compilation didn't explicitly keep it). This change just ensures that the file is kept if compilation succeeds.

So far I have updated one of the optimization remark output tests to add a version with the new pass manager. It is my intention for this patch to also include changes to all tests that use -opt-remark-output= but I wanted to get the code patch ready for review while I was making all those changes.

I know that I called this YamlFile in opt.cpp but that's really unfortunate in retrospect. Can you please call this something like OptRemarksFile or something?

For Out and ThinLinkOut, we do the ->keep() call inside runPassPipeline. I would keep this consistent with the other files.

All remark tests now go through both the old and new pass managers.
