No. boost::filesystem makes extensive use of exceptions, which LLVM is

Hello Jochen- Your expectation is incorrect, I'm afraid. Typically this would be expanded to something like this: … %cmp = … br i1 %cmp, label %ternary.true, label %ternary.false ternary.true: %truevalue = … br label %ternary.end ternary.false: %falsevalue = … br label %ternary.end ternary.end: %value = phi %type [%truevalue, %ternary.true], [%falsevalue,

Hi! Of course nobody wants to implement unicode support for windows because windows should support an utf8-locale and windows is obsolete anyway ;-) But there is a simple solution: use boost::filesystem::path everywhere you use file names and paths, for example in clang::FileManager::getFile. With version 3 opening a file is easy: std::fstream file(path.c_str()). Internally

Now I have a new Problem: I have this function: float foo(float a, float b) { float x = a * b * 0.0f; return cos(0.5) * sin(0.5) * x; }; after compiling it with clang (cpp mode) and renaming _ZSt3sinf to sin and _ZSt3cosf to cos I get the following: define

Hi! when compiling projects using llvm 2.9 and ms vc 10 I get these warnings: 1>e:\Jochen\Lib\lib\include\llvm/Use.h(218): warning C4624: 'llvm::AugmentedUse' : destructor could not be generated because a base class destructor is inaccessible 1>C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\stdint.h(72): warning C4005: 'INT8_MIN' : macro redefinition

I think Chris is saying that the and is necessary because with your i1 trunc you're ignoring all of the high bits. The and implements that. If you don't want this behavior, don't generate the trunc in the first place and just compare the full width to zero.

Hi! Is it possible that you add an example how to write a .o with llvm? Just like examples/ModuleMaker but instead of printing to stdout writing a .o file as starting point for the new MC functionality. -Jochen

It is possible and, since LLVM doesn't support self-modifying code at the IR level, this should not be particularly difficult. It just hasn't been high on anybody's priority list so far. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Feb 17, 2011, at 12:00 PM, <llvmdev-request at cs.uiuc.edu> wrote: >

Hi! In DataTypes.h (generated from DataTypes.cmake) there is an extra code path for Visual C. This can produce macro redefinitions for INT8_MAX, INT8_MIN etc. since other headers may also define them. Therefore please protect the macros like INT8_C etc. Also it would be nice if the auto-generated HAVE_STDINT_H and HAVE_INTTYPES_H would be used also for Visual C since it is possible to add them

Instcombine does of this, late codegen also does some of it. -Chris On May 14, 2010, at 5:58 AM, Jochen Wilhelmy <j.wilhelmy at arcor.de> wrote: > Hi! > > Is there a pass that optimizes vector operations? > If I have for examle a sequence of shufflevector instructions > that optimizes them? > (in opencl notation e.g. a.xyzw.wzyx.xxxx -> a.wwww) > > -Jochen

Can you be more precise about where the error occurs? Depending on where it is, LLVM may or may not be able to propagate the error safely.
