Leonardo, to answer to your questions, yes to all of them  You can take a look at this prototype/proposal: https://reviews.llvm.org/D55585 Overall, computing ghashes in parallel at link-time and merging Types with them is less costly that the current approach to merging. The 35sec you’re seeing for merging should go down to about 15sec. The patch doesn’t parallelize (yet) the Type merging itself, but we have an alternate multithread-...

Sadly the patch on https://reviews.llvm.org/D55585 didn't apply on my clone of llvm at all :( It will take me quite some time to test this out.

Hi, Is anyone working on making the PDB generation on LLD faster? Looking of a trace for linking one of our binaries (it takes 1min6s-1min20s) I see two things: 1) LookupBucketFor(Val, ConstFoundBucket); takes 35s so almost half of the time of linking, mostly finding duplicates 2) There is no parallelization inside of addObjectsToPDB Is anyone working on those? Also has anyone thought about
