similar to: [LLVMdev] Installing clang

Hello. My name is Seung Jae Lee. I'd like to ask you onething about converting to ARM assembly code. I saved the simplest C code shown in your LLVM webpage as 'hello.c' And I made 'hello.bc' by "$ llvm-gcc hello.c -o hello". In order to make ARM assembly code, I typed "llc -march=arm hello.bc -o hello.arm" But, I met this error. llc: ARMISelDAGToDAG.cpp:73:

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

Xi, I just installed VS2005 pro w/ SP1 for Win Vista.

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

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

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

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?

Dear Prof.Adve and Bill, I deeply appreciate your comments and concerns. (Please forgive my late response. I've tried some more cases to make this issue) As Prof.Adve mentioned, I need to explain exactly what my problem is, but I have no good ability that I can explain it in this plain text space. For this reason, I made a .pdf file and linked it as follows:

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

Hi Seung, It should be fairly straight-forward to do in LLVM. Once you identify the loops, then identify the PHI nodes that you need to convert, then apply the transformation below. The fine details on how to create an instruction and replace one instruction with another are documented in the docs section and in other code. :-) One thing to be careful of, if you convert a variable like

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 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

I simply found it at: http://getgnuwin32.sourceforge.net/ Seung ---- Original message ---- >Date: Tue, 12 Feb 2008 21:11:04 -0800 >From: "Ted Neward" <ted at tedneward.com> >Subject: Re: [LLVMdev] Is there someone tried LLVM 2.1 on Visual Studio 2005? >To: "'LLVM Developers Mailing List'" <llvmdev at cs.uiuc.edu> > >I'm sorry,

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

Thank you for your kind explanation. I did it as you mentioned. That is, I set '-march=x86 hello.bc' in the Command Arguments. (I also set my compiled LLC, i.e., LLVM_ROOT_DIR\win32\debug\llc.exe, in the property name Command.) But, when I made a breakpoint in main( ) of llc.cpp and then started to debug I found the 'InputFilename'(llc.cpp:176) is shown like {???}. Therefore it

Hello, guys. I just tested -reg2mem pass to see how it changes my bitcode. E.g., for the following simple C code: ------------------------------------------------------------- int foo() { int i,j; int sum = 0; for (i=0; i<10; i++) { sum += i; for (j=0; j<3; j++) sum += 2; } return sum; } ------------------------------------------------------------- I could get the

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?

Thank you so much for this info. That's exactly what I want. But, I'm still not sure about using -g. Let me imagine I am modifying x86 assembly instructions and trying to test it with 'hello.c' to check out the assembly is properly emitted. I should type "$ llvm-gcc hello.c -o hello" to have the bytecode of 'hello.c'. And then I can have an x86 assembly mnemonics

Hi, guys. I'm interested in using reg2mem pass but not sure about the concept of it. Can you let me know a reference about it, if any? Forgive my ignorance. -_-; Thanks, Seung J. Lee
