Hi all, I tried using dragonegg to compile some numerical software of ours. I tried out two different approaches expecting both would yield the same results: 1. gfortran-4.6 -fplugin=dragonegg-3.0 -o test.o test.f (I ommitted a bunch of additional arguments for brevity) 2. gfortran-4.6 -fplugin=dragonegg-3.0 -fplugin-arg-dragonegg-emit-ir -S -o test.ll test.f llc -O0 -o test.s test.ll as

I am trying to implement loop unrolling in a context, where lots of constant propagation has taken place. Unrolling an outer loop might make an inner loop have constant bounds, therefore I want to process the loops outside in, i.e. from parent loops to nested loops. Unfortunately the standard loop pass manager performs loop passes inside out, i.e. from nested loops to parent loops, thereby missing

Hi all, I stumbled across a peculiarity regarding constant propagation that I don't understand. I'm not sure, if I oversee anything or if it's a missing feature. I have created the following simple test function in C: int times_zero(int a) { return (a * 0); } Compiling this with GCC using dragonegg generates the following code: %int = type i32 define i32 @times_zero(i32 %a)

Hi Anton, yes the first command line contained -O0 as well. I also tried omitting -O0 from the llc command line, but this made no difference.

Hi all, I need to look at the CFG of a loop during debugging. However the containing function is very large, so it is rather difficult to use the CFG of the complete function. I tried using the ViewGraph method, but the compiler kept complaining about undefined symbols related to GraphTraits or DOTGraphTraits. Is there any example that I could look at to find out, what exactly I need to call

Hi all, I'm rather new to LLVM and intend to dive into partial evaluation with LLVM. I tried to run the example from http://llvm.org/devmtg/2008-08-23/llvm_partial.pdf, which worked after some adaptations, which were necessary, because LLVM evolved since the slides were made. However, I also tried to get the same example running as an optimization pass following the instructions in
