...inlining a number of Modules (selectively, but that seems unrelated), works the first time, but crashes the second with the "mapping to a source type" assertion. I'm not 100% sure yet, but my understanding of what happens is the following: 1) "main1" module gets created 2) inlinining loads module "a", clones it, links module "a'" into "main1". This module contains an opaque struct definition "t" that is now referenced by "main1'". 3) inlinining loads module "b", clones it, links module "b'"...

Hi folks, I am wondering about the relationship clang, opt and llc. I understand that this has been asked, e.g., http://stackoverflow.com/questions/40350990/relationship-between-clang-opt-llc-and-llvm-linker. Sorry for posting a similar question again, but I still have something that hasn't been resolved yet. More specifically I am wondering about the following two approaches compiling

...inliner. What Dehao has found in his experience with GCC is that in order to help the inliner, SamplePGO needs to become a module pass. Mainly, it needs to be able to affect inlining decisions. If a branch into a call site has many samples, we want to tell the inliner about it so it increases the inlinining score for that call site. Additionally, SamplePGO may need to actually perform some inlining before the inliner runs. This is needed to better match the samples obtained from optimized binaries. For example, suppose the binary had 3 functions A(), B() and C() all calling function foo(). When th...
