At the LLVM Developer Meeting Michael showed double digit compile-time increases in clang 3.7 and 3.8 in Os/O3 and O0 in his Loop Passes presentation (https://llvmdevelopersmeetingbay2016.sched.org/event/8Z0B/loop-passes-adding-new-features-while-reducing-technical-debt <https://llvmdevelopersmeetingbay2016.sched.org/event/8Z0B/loop-passes-adding-new-features-while-reducing-technical-debt>): The selection of 10 tests out of the LLVM tests invites criticism. The motivation h...

Hi LLVM’ers! We are hosting a BoF at this year's Dev Meeting on a subject we hope will be of interest to some (many?) of you: shipping software (entirely) as LLVM IR. You can find our proposal in the meeting schedule online: https://llvmdevelopersmeetingbay2016.sched.org/event/8Yzq/shipping-software-as-llvm-ir The BoF is scheduled to last 45 minutes, which will go by very quickly! To make the best use of the time, we'd like to get a head-start on some of the discussions, and get a feel for what topics people are most interested in discussing. To star...

I think the best way to understand LLVM is by playing with it. Then you should try doing some
