[LLVMdev] Documentation about converting GIMPLE IR to LLVM IR in LLVM-GCC/DragonEgg
Dear All,
I am trying to understand the process followed for converting GIMPLE IR to
LLVM IR in LLVM-GCC/DragonEgg - more importantly conversion of OpenMP
extended GIMPLE IR to LLVM IR. It would be great if anybody points me to
some documentation before I my-self delve into the understanding of related
source code.

Cheers

[LLVMdev] multi-threading in llvm
Hi Alexandra,
I don't know much, maybe this topic should be bridged with polly-dev
(adding it to CC) to bring it more attention.
Indeed, polly uses ScopPass, that creates serious limitations in
compatibility with other passes. To my understanding, scops are used
because ISL loop analysis tool uses scops. In fact, just for handling
OpenMP directives scops are not required, unless one need to

[LLVMdev] multi-threading in llvm
Hi,
I want to execute the iterations of a loop in parallel, by inserting calls either to pthreads or to the gomp library at the LLVM IR level. As a first step, I inserted an omp pragma in a C file and compiled it with llvm-gcc to check the generated LLVM code. If I understand correctly, to parallelize the loop in LLVM IR, I have to separate the loop in a new function, put all required parameters
