similar to: [LLVMdev] dragonegg + jit ?

Apologies if this gets double posted. A subtle question about Dragonegg: is Dragonegg usable for Just-in-time compiling as well as ahead-of-time compilation? If not, how hard would it be to enable JIT using dragonegg? Say one wanted to use the gnu fortran-2008 front end, and to jit up some fortran code. How difficult would it be to adapt it? Thank you.

Hello All, Another newbie question. I am confused as to what options will work with "fplugin-arg-dragonegg-llvm-option" for dragonegg plugin. Readme says it is used to pass command-line options to llvm. I shall consolidate into 3 questions. For all examples below, I used combo- gcc 4.6 + dragonegg(trunk) + llvm(trunk) (1). Does 'fplugin-arg-dragonegg-llvm-option' allow all

Looks like recent changes to Attributes.h broke the dragonegg build.

Hello, With GCC, it is possible to compile GIMPLE from an object file back to assembly. With Dragonegg, it seems to be a NOP. (See below for a comparison.) This appears it could be a nice way to mix the strengths of GCC and LLVM. If it worked.. Should it?

Hi Jack, thanks for these numbers. Can you also please measure compile times? I'm thinking of enabling gcc optimizations by default, but I don't want to increase compile times, which means choosing a value for the -fplugin-arg-dragonegg-llvm-ir-optimize option that is low enough to get good compile times, yet high enough to get fast code. It would be great if you could play around with

hi, I have dragonegg r131864, gcc-4.5 r174052 and llvm r131897. When i tried to make the llvm test-suite, i got a error message: /home/ether/local/gcc-4.5/bin/gcc -fplugin=/home/ether/sources/dragonegg/dragonegg.so -I/home/ether/build/llvm-ts/projects/test-suite/SingleSource/UnitTests/Vector/SSE -I/home/ether/sources/llvm/projects/test-suite/SingleSource/UnitTests/Vector/SSE

Hello All, I am in need of dragonegg support for the latest version of llvm. I tried to make dragonegg with the latest versions but it fails. It is able to be maked with the llvm version 3.3 only with GCC 4.6. I am trying this on my ubuntu system. I tried to make dragonegg with various combinations of llvm and GCC versions but the only combination which seems to be working is LLVM-3.3, GCC-4.6

Hi Tom, DragonEgg depends on GCC's and LLVM's internal headers, auto-host.h is one of them. Try to add GCC and LLVM_CONFIG with your make command as described here http://dragonegg.llvm.org/ in section "Getting it". Best, - Dima.

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'm the package maintainer for DragonEgg for Fedora. I've just tried to update the DragonEgg package for Fedora 19 beta, which uses gcc 4.8.0. I had to modify the DragonEgg Makefile because llvm-config --libs is generating the names of the static libraries, while I need to link to the dynamic library (libLLVM-3.3.so). I don't think this is the cause of my problem, but I suppose I

The Polyhedron 2005 benchmark results for dragonegg svn at r141492 using FSF gcc 4.6.2svn measured on x86_64-apple-darwin11 are listed below. The benchmarks used the optimizaton flags... -msse4 -ffast-math -funroll-loops -O3 in all cases. The use of -fplugin-arg-dragonegg-enable-gcc-optzns to allow for autovectorization from the FSF gcc front-end only produces a single run-time regression,
