similar to: [LLVMdev] can llvm generate .so and even .dll?

Nope, you'll have to call the system linker. =/ Reid On Fri, Feb 18, 2011 at 8:08 AM, Jochen Wilhelmy <j.wilhelmy at arcor.de> wrote: > Hi! > > if llvm can generate .so and .dll my bytecode cache problem would be easily > solved by creating shared libs for the target platform and loading them. > > -Jochen > > _______________________________________________ >

Hi! > sin/cos etc should already be handled by lib/Analysis/ConstantFolding.cpp. > Thanks for the hint and it works! 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! 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course nobody wants to implement unicode support for windows because windows should support an utf8-locale and windows is obsolete anyway ;-) But there is a simple solution: use boost::filesystem::path everywhere you use file names and paths, for example in clang::FileManager::getFile.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

Hi! Is it possible to implement a byte code cache for a llvm-jit? This way the compile time occurs only once and the next time the compiled machine code can simply be loaded from disk. Of course care has to be taken with function pointers that are used as constants since they may change on the next run. -Jochen

Now I have -DLLVM_INCLUDE_EXAMPLES:BOOL=OFF but Kaleidoscope is still there and selected for build (-G "Visual Studio 9 2008") -Jochen

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

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

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

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,

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

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! I have a llvm::Module that references an external function and a second mdoule that implements the function. The implementation consists of only one instruction. How can I explicitly inline this function? -Jochen

Hi! is there a way to get the c backend using llvm::TargetRegistry::lookupTarget()? e.g. llvm::TargetRegistry::lookupTarget("c", error)? - Jochen
