similar to: [LLVMdev] Problem about "llc -march=msil"

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, Artur > // CallSites have equal signatures > bool MSILWriter::cmpCallSite(CallSite A, CallSite B) { >   return (getCallSiteFType(A)==getCallSiteFType(B) && >     A.getAttributes()==B.getAttributes()); > } As it is impossible to honour argument attributes in MSIL I don't see why you should compare attributes. You seems to have the same MSIL call signature for calls

Hi all! I gave a shot at compiling core llvm with a Solaris 9 machine. The compiler is FSF gcc 3.4.6. I am building trunk in the release version. So far I did not run tests (no dejagnu installed). Here are my findings: 0) Configuring. I had to suppress the solaris tools by: env AR=/opt/gnu/bin/ar NM=/opt/gnu/bin/nm RANLIB=/opt/gnu/bin/ranlib STRIP=/opt/gnu/bin/strip ../llvm/configure

Hi, I am using llc (llvm 2.9) to generate the MIPS assembly, but failed when compile any codes with va_start()/va_end()/va_arg(). Here is the minimal step to reproduce the failure: llvm-gcc-4.2 -emit-llvm hello.c -c -o hello.bc llc -march=mips hello.bc -o hello.s llc show this erroe message: LLVM ERROR: Cannot select: 0xa1873a0: ch = vaend 0xa187290:1, 0xa185ae0, 0xa187318 [ID=38] 0xa185ae0:

Hi, The problem is resolved. I try the svn trunk, llc work fine to generate the MIPS assembly. Also, I try both llvm-gcc and clang, they work fine at my current project, though I will use clang to instead of llvm-gcc. Thanks, everyone.

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

Ah, sorry. I missed that you're doing variadic calls, not casting variadic function to definite ones. I think you

Maybe I misunderstood something but I just get the variadic declaration not the real "signature", like this: const

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

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.
