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

It's LLVM-to-MSIL translator. So, if the source use some unsupported code... The same situation

MSIL is definitely much more high level than LLVM, that's why significant portion of information will

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.

Hi Everyone, It is getting to be that time again. I've scoured llvm-commits and collected a list of some of the major features we've developed since the last status update (from Feb 21). Please take a look and send me (off list) additions, feedback, corrections, etc. As usual, if I missed something, it's probably because there is such a huge amount of stuff happening,

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

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

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 05-11-2008 19:47 Para: LLVM Developers

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.

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

Hi everyone! I am working on a .NET based project (actually written in C#). During the coding, we have noticed many inefficiencies of C# compiler to optimize code. Compiler performs only a few optimisations. A vital optimisation, inlining, is missed. The JIT-er has rules not to inline methods containing structs as parameters (this is really stupid!) and inlining methods longer than 20 bytes
