Yes I could, however upsteam appears to maintain llvm in svn.
There is a git repository as well but it lacks branches and tags.

Additionally the branch history doesn't look very linear and so far i've fa=
iled
to match the proper commit from the branch in master.
For example the top commit in

tp://llvm.org/svn/llvm-project/llvm/tags/RELEASE_352/final is:

SimplifyCFG: Avoid miscompilations due to removed lifetime intrinsics.

    SimplifyCFG: Avoid miscompilations due to removed lifetime intrinsics.


However mesa 10.5.5 doesn't build against that llvm (doesn't like
TM->getSubtargetImpl()->getInstrInfo() in lp_bld_debug.cpp), but it d=
oes build
against 3.5.2.


Can you suggest some commit ids i could use as good and bad markers?
