[Mesa-dev] New JIT Features in LLVM

[preejackie]

Hi

I'm Praveen Velliengiri, student from India. I'm working on developing a 
Speculative compilation support in LLVM ORC JIT Infrastructure.

As LLVM ORC supports compiling in multiple backend threads, it would be 
effective if we compile the functions speculatively before they are 
called by the executing function. So when we request JIT to compile a 
function, JIT will immediately returns the function address for raw 
executable bits. This will greatly reduce the JIT latencies in modern 
multi-core machines. And also I'm working on designing a ORC in-place 
dynamic profiling support, by this JIT will automatically able to 
identify the hot functions, and compile it in higher optimization level 
to achieve good performance.

I'm proposing this project for GSoC 2019. It would be helpful to know 
how this new features are effective to Mesa library, so that I include 
your comments in "View from Clients" proposal section.

Please reply :)

Have a great day!
