similar to: [LLVMdev] Is this bug in LLVM?

#include <stdio.h> int main() { printf("hello world\n"); return 0; } “$ llvm-gcc hello.c -o hello” “$ llc -march=arm hello.bc -o hello.arm" made error as follows: llc: ARMISelDAGToDAG.cpp:73: llvm::SDOperand LowerCALL(llvm::SDOperand, llvm::SelectionDAG&): Assertion `isVarArg == false && "VarArg not supported"' failed.

Hello. Nice to meet you. My name is Seung Jae Lee, a graduate student in UIUC CEE, who is working in NCSA for the present. Nowadays I am trying to develop LLVM backend to spit out CHiMPS assembly code. In the process, I installed LLVM codes on my home directory in the host computer. But I don't think it was installed properly. While bootstrapping the LLVM C/C++ Front-End, I met several

Hi all, I had little success installing llvm inside scratchbox for an ARM build so have been trying to generate assembly code for arm using the llc utility. However, llc fails to generate code for arm. Output is as below... arvind at zeus:~/tools/llvm/del$ llc main.bc -o mainarm -filetype=asm -march=arm -f llc: ARMISelDAGToDAG.cpp:73: llvm::SDOperand LowerCALL(llvm::SDOperand,

Hello. I am Seung Jae Lee making a LLVM backend for a new architecture XCC. I found that the instructions use variable names which actually used in the source coding for operands unlike most architectures which use usually register names or addresses as operands. LLVM backend examples such as ARM, SPARC seem to use register names or addresses for operands. How can I implement this on my backend?

HI Arvind, I think you are using an old llc version. VarArg support was implemented a long time ago.

Hello. I am trying to run tblgen so I typed $ tblgen ARM.td -print-enums -class=Register in "llvm/lib/Target/ARM" But I got an error as follows: Included from ARM.td:18: Parsing ../Target.td:16: Could not find include file 'llvm/Intrinsics.td'! As you know, the 16th line of Target.td includes "llvm/Intrinsics.td". But this cannot find Intrinsics.td, I think. Of

Thank you for this information. If so, is there any way to grasp which kinda data throw in and out in LLVM as shown in such a way in gdb?

Hello, LLVMers. I just wonder How I can pronounce Clang. [see-laeng], [see-lang], [k-laeng], [k-lang]?? Thanks, Seung

Thank you, Bill. Seems to be better. Anyway...Is there a way I can do what you showed for me? Thanks, Seung J.

Thanks for your comment. I also tried for LLVM 2.2 but got the same compilation errors on VS2005. (I didn't modify anything before the compilation) I just wonder if I need bison and flex even just in the case of compiling them on VS2005 without changing anything because the LLVM doc says "If you plan to modify any .y or .l files, you will need to have bison and/or flex installed where

I followed the steps in "Getting Started with the LLVM System using Microsoft Visual Studio" in the document in LLVM page. I made hello.c file exactly same shown in the page. I made hello.bc on UNIX and transferred it to my Windows computer. And I typed "llc -march=c hello.bc" (Of course, I downloaded the latest version of LLVM and compiled with VS before this.) But my command

I have always built it with flex and bison installed, though I believe Chris removed our last dependence on flex a little while back, so you may not need that. I'm using bison 2.1 which I got from the getgnuwin32 folks. I imagine that if you have cygwin or the like, you probably already have everything. You will need to have the executables in your path. I build with VisualStudio 2k5

Thank you so much for your reply, Chris. If so, can I ask you two things more? First, is there any way to have various optimizations on LLVM assembly such as -O options in llvmc? llvm-gcc doesn't seem to be working for these -O options... Second, I'm still not sure about difference between *.s and *.ll. LLVM assembly *.s file can be made from llvm-gcc -S. Another assembly *.ll file comes

Hi, I am trying to write a LowerCALL() function for my (custom) target ISA. All I need to do is map a CALL instruction directly onto an SDNode that takes an equal number of arguments (very much alike intrinsics, except that these are custom to my target.) I do not need to implement any call sequences, stack frames etc. I get the following assertion failure: llc: LegalizeDAG.cpp:834:

Really happy to hear llvm has the brand-new front-end. But, unfortunately, I failed to install it. When I 'svn co http://llvm.org/svn/llvm-project/cfe/trunk clang' in llvm/tools folder, I got this message.. svn: REPORT request failed on '/svn/llvm-project/!svn/vcc/default' svn: REPORT of '/svn/llvm-project/!svn/vcc/default': 400 Bad Request (http://llvm.org) Am I missing

Hello all, Is there anyone has tried LLVM 2.1 on Visual Studio 2005? I did but not succeed due to some build errors. I seem to remember I read somewhere on this list it's compiled on VS2005 so I wonder... Have a good night. Thx, Seung
