[LLVMdev] GSOC - HLVM Work

[Christopher Lamb]

Gabe,

I'm quite new to hacking on LLVM, but I'll give you an idea I had  
reading some of the recent dev list posts. I think investigating  
concurrency with regards to LLVM would be very useful (what with  
multi-cores and all). This could be concurrency in regards to GC, or  
it could be simply looking at how LLVM can best interface with  
standard concurrency paradigms (OpenMP, MPI) for the languages it  
supports. With a GCC 4.2 front-end port of the front-end available  
what is necessary to enable OpenMP support? Given a FORTRAN front-end  
based on GCC is being considered how could high performance numeric  
codes benefit from some aspect of LLVM?
