[llvm-dev] ThinLTO status in trunk?

[Teresa Johnson via llvm-dev]

Hi Vikram,

Thanks!

I'm not sure what part got committed in the 3.8 timeframe - it looks like
that was released back in March? A number of fixes have gone in since then
so I would stick with a more recent version. The ThinLTO in trunk and
(presumably 3.9 which seems to have not yet gone out?) is complete and
working with multiple threads using gold.

The distributed build support is also in (which needs support in the build
system however), although I am fixing a few bugs right now that popped up
in testing our internal apps. Which distributed build system do you use? We
have support coming out in Bazel, which is our open sourced distributed
build system.

Let me know if you run into any issues or have any other questions!

Teresa
