[PATCH] D141135: [RFC][GlobalISel] Replace the current GlobalISel matcher with a bottom-up matcher

[Kai Nacke via Phabricator via llvm-commits]

Kai updated this revision to Diff 487095.
Kai added a comment.

I restructured the YAML output used for the test. As a result I could remove the sorting code, which caused a longer running time of the algorithm. The construction of the matcher is much faster now. However, testing got more challenging. I also made some minor changes in other parts of the algorithm. The generated matcher code is unchanged..
