Hi, I'm playing around with llvm and the Kaleidoscope tutorial and first of all I have to say I'm really impressed. LLVM rocks! Unfortunately I've now run into a linker error while trying to optimize the IR or turn it to bitcode and likely due to my very limited experience with c++ I just can't figure out how to resolve it. The linker complains that the llvm::WriteBitcodeToFile

Hello With the latest LLVM from Subversion (rev48737 from http://llvm.org/svn/llvm-project/llvm/trunk) I'm getting make[2]: Entering directory `/usr/src/Lang/llvm/_Obj/lib/AsmParser' llvm[2]: Flexing Lexer.l llvm[2]: Compiling Lexer.cpp for Debug build /usr/src/Lang/llvm/lib/AsmParser/Lexer.l: In function 'int llvmAsmlex()': /usr/src/Lang/llvm/lib/AsmParser/Lexer.l:278: error:

Hi Daniel, attached is a patch that pushes most of the object file specific parsing out of AsmParser and down into MachOAsmParser. This was done as a cleanup for the ELF work. I know that you're not happy with this approach, particularly the fact that as we add more object file formats and assembler dialects, it's going to cause a class explosion. But I was hoping that we could use this

There is already a parser library inside LLVM framework and you can use it directly without any problems. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hi everyone, I'm currently in the first year of my PhD, and I'm going to be looking at an experimental IR for my thesis. After looking at a variety of research compilers I've come to the conclusion that LLVM is the nicest to work with for my purposes. I was considering writing the code to construct this experimental IR from LLVM assembly, and then at the end of the process (i.e. new

Hi Eli and Others In response to your feedback, I have taken care of all your review comments - I removed clangOMP.a and moved the implementation of "class OmpPragmaHandler" to "clangLex.a". The attached zipped file - namely - 'OpenMP_support_in_Clang.tar.gz' contains all the implemented "patches" along with *newly* added source files. Another attached text

I am unknown to all the stuff happening in and around LLVM, as i am interested in the project but had not time to dig in, yet. Just reading here and there a bit. But i wanted to share my 2 cents on the Lexer topic. I have written multiple lexer/parser for private purpose and recently one for our product to compile Mathematical expressions into an internal format for evaluation. So far i usually

Hey, I am designing/implementing a very simple "flow control language" [1] I want to use in my HTTP server. I am still very new to LLVM and I've already the lexer and parser part working pretty well, however, the code generator (runner) does not yet feel as comfortable as I want. Precisely, I want this language to be extensible in terms of custom variables - of type string (i8*) or

Hello: I've been trying for days now to get igraph working on a debian sarge install. There does not appear to be any pre-built packages, and when I try and install within R, it blows up on the final linking, claiming its unable to find libgfortran (which IS installed, and IS working for all other users of the compiler). I started up R and ran: install.packages("igraph"). It

Can an expert tell me how to compare the kaleidoscope implementation with the LLVM's compiler implementation. I mean can anyone tell me about the lexer, parser, codegen related .cpp and .h files inside the LLVM solution project. I would like to understand the LLVM's compiler in the same

Thank you very much for replying. Then I have another question: Before I start, I want to choose the best platform to develop my project. Would you please tell what is the best OS platform to develop the llvm project? There are several choices: Mac OS X, FreeBSD, Linux and Windows. Your opinion is eagerly expected.

Hi everyone. Because there is still a little confusion about the huge document, I want to know what llvm can provide when we customize our new compiler? For example, a normal compiler includes lexer, parser, intermediate code generator , optimizer and target code generator. According to llvm documents, it seems that llvm can provide a better intermediate code presentation. And what else can it

I would like to modify the compiler to classify variables, which will ultimately determine the position the variables are stored in memory. What would be the best approach to accomplish this? I was thinking of modifying the lexer and parser to add a new attribute and have the machine code generator handle memory mapping accordingly. Does anyone have experience with this sort of exercise? How
