Hello all. is it possible to use LLVM to optimize existing .NET assemblies? Basically doing the following: - read in MSIL and convert into LLVM internal representation - perform global optimizations on LLVM internal representation - write out optimized MSIL using the existing LLVM backend I presume that the capability to convert MSIL into LLVM internal representation exists somewhere in VMKit. The reason I need thi...

Hey there, Searching via the web is not producing answers.... So I thought I would ask the gods of llvm. :-) I'd like to experiment with the llc in conjunction with msil. but I am running into this error: llc-mp-2.9 test.ll -march=msil /opt/local/libexec/llvm-2.9/bin/llc: error: invalid target 'msil'. the version string is: llc-mp-2.9 --version Low Level Virtual Machine (http://llvm.org/): llvm version 2.9 Optimized build. Built May 31 2012 (21:15:...

Hello, I work in Kalray (Montbonnot, France) and I'm PhD student at Universite Joseph Fourier in Grenoble. We want to use LLVM framework for MSIL code generation, which is part of my thesis. Currently I'm still reading LLVM's documentation and I've started completing the MSIL backend for running on Mono. Things that need to be fixed include pointers initialization, call to vararg functions, incorrect stack fill after some fun...

It's LLVM-to-MSIL translator. So, if the...

Hello, Everyone. We've just commited new backend for LLVM: MSIL. The author of backend is Roman Samoilov from Codedgers Inc. (roman at codedgers.com). Backend itself is very similar to C backend (and actually was based on it). Note, it's pure LLVM-to-MSIL translator, so no additional checks etc. are performed. Backend is usable in general, but still lacks...

Hello everyone, I'm a little new to LLVM. I know that the backends are still in experimental stage. MSIL and MIPS would be very useful for a project that I'm working on. Do you have any plans to have it completed in the next few months? I could generate the MSIL assembly but when compiled it, which compiles sucessfully, it generates invalid opcode errors.

Both backends are important but I find it more important the MSIL backend, for now. It's a shame that nobody is picking up the MSIL backend; it would be useful another backend that is machine-independent and that has support for several tools. -----Mensagem original----- De: llvmdev-bounces at cs.uiuc.edu em nome de Bruno Cardoso Lopes Enviada: qua 05-11-20...

Consider we will have some FE for MSIL, which will just generate LLVM's "call" instruction with some predefined CC, which...

Hi, I am trying to use llvm to translate ftp.c(a file of wget-1.11.2.tar.bz2 ) to msil. But it shows errors like: [dayin at localhost src]$ llvm-gcc -emit-llvm ftp.c -c -o ftp.bc [dayin at localhost src]$ llc ftp.bc -march=msil -o ftp.s Intrinsic ID = 32 llc: /home/dayin/llvm/llvm-2.2/lib/Target/MSIL/MSILWriter.cpp:802: void <unnamed>::MSILWriter::printIntrinsicCall(const l...

...lower than if they were coded manually (manual inlining). This is certainly not acceptable for me. I am really big fan of LLVM. I guess I could use LLVM for post-compile step (actually install-time step). LLVM could perform optimisations on my code in the following manner: - translate code from MSIL - optimize code (inlining, probably other cool optimisations) - translate back to MSIL Is this possible with LLVM. If not, will it ever be possible (is someone working on that). Thank in advance for reply, Žiga osolin
