similar to: [LLVMdev] a very basic question about LLVM IR structuredness

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 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

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

Ok, here are a few suggestions and comments: 1) LLVM has the capabilities to do everything that you are trying to re-implement. 2) Have you looked at the C backend? It recreates loops. It may not create "for" loops but you can hack on it to do that. 3) The way you are converting out of SSA is wrong. You will suffer from lost copies. You should look at using demotePHI(). see

Hello. I wonder how I can use the options of LLVM commands in Visual Studio Debugging mode. For example, If I want to follow the pass on 'llc -march=x86 hello.bc' in the Visual Studio's debuggin mode, how can I let it know the options such as '-march=x86 hello.bc'? I can set the breakpoint in main() in llc.cpp but I can't let it cognize that I want X86 assembly code from

Hello, guys. I've tried to use llvmc to test optimization options but wasn't successful. Would you mind telling me what's wrong with this? ------------------------------------------------------------- $ llvmc chc_03.c -O3 -o chc_03 terminate called after throwing an instance of 'std::string' llvmc((anonymous namespace)::PrintStackTrace()+0x15)[0x8086091]

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

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

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:

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

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:

By the way, somebody (I think it was Chuck, but I don't remember for certain) was asking for the BuildLog.htm from building the llvm.sln file under VS 2005 SP1 for diagnostic purposes; right now the SLN is configured to produce a new BuildLog for each and every one of the projects inside the solution. I don't know who's responsible for this guy, but that's probably not the best way

Dear LLVM guys, Hi. I first became to be interested in the compiler work, especially LLVM, since last October, still I'm a novice on here. (My major is not CS, either. :-\) Please forgive my ignorance. LLVM optimization and other tools are really fantastic. However I don't want LLVM breaks my 'for' statement in C code into basic blocks during compiling. I'm sure this sounds
