Hi Alan,
Here are the patches that port merge similar functions to the ThinLTO
-https://reviews.llvm.org/D52896
-https://reviews.llvm.org/D52898
-https://reviews.llvm.org/D52966
-https://reviews.llvm.org/D53253
-https://reviews.llvm.org/D53254
Before merging the patches we wanted to improve the comparison of IR Types.
That project started in the GSoC this year and the patch to improve
comparison or IR Types is posted by Vishal:
