[PATCH] D20988: [cpu-detection] Substantial refactor of Host CPU detection code (x86)

[Alina Sbirlea via llvm-commits]

asbirlea added a comment.

A clarification: the end goal of this refactoring is to address Bug 25510, adding __cpu_model to compiler_rt.
The split for types and subtypes is intended to facilitate that, similar to the split libgcc uses. 
That one has a pretty limited set of archs, hence new ones were added here. In practice, I'm sure I did not do the best job with the split (and it was not the primary focus either), so suggestions for moving/renaming types/subtypes are welcome.
