...s to UBSan (like the one that I talked about earlier). http://clang.llvm.org/docs/UsersManual.html This page below doesn't seems to mention UBSan at all (unlike the others most commonly used sanitizers).

...tus of it? Do you have a rough idea of how much time will it take to implement the new LTO API for someone who is new to the project? What are the main benefits of the new LTO API and why it’s important/beneficial to finish this before starting to work on unifying Thin/FullLTO pipeline? Thank you! Katya.

...hen doing FullLTO for b.o/c.o. (i.e., the previous non-permeable barrier between ThinLTO and FullLTO groups will become permeable in one direction). However, do you think by doing this, we will achieve a better performance than doing ThinLTO backend for all of the files (a.o, b.o, c.o)? Thank you! Katya.

I had just installed Linux Mint katya on my Dell Dimension 5000 computer because Windows kept making it lag and so on.

I've googled for solutions to this problem an...
