Hello everybody, we noticed that llvmgcc4.2-2.2 sometimes generates non-natural loops when compiling to bytecode without any optimizations. Apparently what happens is that the loop header is duplicated, which results in two entry points for the loop. Since this could obstruct subsequent loop optimizations, it might be interesting to further investigate this behavior. To show the problem, I have

Now that I have HLVM up and running on x86 and x64 I am interested in testing it out on an ARM in preparation for their imminent world domination. I believe LLVM already has excellent support for the ARM thanks to Apple's ARM-based products. However, I'd really like an ARM-based consumer device suitable for developing and testing HLVM on, rather than using a cross compiler and

It seems that tail duplication can make a reducible CFG irreducible (example below). Is that intentional? Are there other optimizations that have that property? Is irreducibility a problem for existing LLVM passes? It looks like there was once an open project for a pass to make irreducible graphs reducible. Was that ever implemented? - Mark ; "opt -inline -tailduplicate" makes an

Hello all, I would like to participate in this year's Google Summer of Code and I am sending you a short description of my proposal. I have written the formal proposal already and if someone is interested I can send him the pdf. One of the open projects in the LLVM list is to enhance LLVM with static profiling capabilities. LLVM already provides a unified structure for writing pro
