[LLVMdev] GSOC Adaptive Compilation Framework for LLVM JIT Compiler

[Reid Kleckner]

Neat project idea!

When we used the JIT for Unladen Swallow, one of our pain points was that
code generation took a very long time. Just turning off the IR optimizations
had negligible impact on compilation time.  Things may have changed these
days, but I would start by having the adaptive JIT splat out code with fast
isel and fast regalloc.

I see that you put it outside the scope of your project, but eventually it
would be nice if the first code could be instrumented in a way that gathers
information to the as-yet unimplemented profile guided optimizations.
