llvm

I am having no luck the last few days since Xcode 5.1 came out. I keep getting this error on an old project that supports iOS 6.0: ERROR: clang: error: unknown argument: '-fno-obj-arc' [-Wunused-command-line-argument-hard-error-in-future] clang: note: this will be a hard error (cannot be downgraded to a warning) in the future Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1 There are not many posts about this on the internet and some suggestions seem to be to change your CFLAGS but I have no idea how to do that in

If I build a static library with llvm-gcc, then link it with a program compiled using mingw gcc, will the result work? The same for other combinations of llvm-gcc, clang and normal gcc. I'm interested in how this works out on Linux (using normal non-mingw gcc, of course) and other platforms as well, but the emphasis is on Windows. I'm also interested in all languages, but with a strong emphasis on C and C++ - obviously clang doesn't support Fortran etc, but I believe llvm-gcc does. I assume they all use the ELF file format, but what about call conventions, virtual table layouts etc? Yes, for C

I want to read (parse) LLVM IR code (which is saved in a text file) and add some of my own code to it. I need some example of doing this, that is, how this is done by using the libraries provided by LLVM for this purpose. So basically what I want is to read in the IR code from a text file into the memory (perhaps the LLVM library represents it in AST form, I dont know), make modifications, like adding some more nodes in the AST and then finally write back the AST in the IR text file. Although I need to both read and modify the IR code, I would greatly appreciate if someone could provide or

From what I've read, there is a llvm program that converts java bytecode to llvm's intermediate form called class2llvm. My question is, how do I access this. What front end do I have to install in order to access this. VMkit is their implementation of a JVM, but I am looking for how to compile the java source code with llvm, not how to run it. The Java frontend translates Java bytecode (.class files) into LLVM bytecode. Take a look at this link: https://llvm.org/svn/llvm-project/java/trunk/docs/java-frontend.txt lei_z You may take a look at dragonegg , which enables llvm to use gcc's frontends

Is there an easy way of going from llvm ir to working source code? Specifically, I'd like to start with some simple C++ code that merely modifies PODs (mainly arrays of ints, floats, etc), convert it to llvm ir, perform some simple analysis and translation on it and then convert it back into C++ code? It don't really mind about any of the names getting mangled, I'd just like to be able to hack about with the source before doing the machine-dependent optimisations. There is an issue here... it might not be possible to easily represent the IR back into the language. I mean, you'll probably be

First of all, I've followed "Getting Started: Building and Running Clang" . In particular, I've built it according to "Using Visual Studio" section. In other words, I've built it using Visual Studio 2010. Secondly, I've manually set include and library paths to MinGW distribution: The simple program I'm trying to compile: #include <iostream> using namespace std; int main() { cout << "Hello, World!" << endl; return 0; } I get the following feedback from the compiler: In file included from C:\MinGW\lib\gcc\mingw32\4.5.2\include\c++\iostream:39: In file included from C:\MinGW\lib\gcc\mingw32\4.5
