Hi While compiling the ConstantProp.cpp I am getting the following error. error: too few arguments to function ‘llvm::Constant* llvm::ConstantFoldInstruction( llvm::Instruction*, llvm::LLVMContext&, const llvm::TargetData*) I am using llvm-2.6 and the ConstProp.cpp file is http://llvm.org/docs/doxygen/html/ConstantProp_8cpp_source.html and the exact error message is: llvm[0]: Compiling ConstantProp.cpp for Release build (PIC) /home/tarun/De...

I can't imagine any uses for a method like that besides a pass like yours. (This method is essentially the opposite of ConstantFoldInstruction, and is therefore usually the opposite of what we want to do.) Anyone else have any ideas for uses? That said, it should be pretty simple to write recursively: first, transform all the constants that use the current constant (this must be possible due to the constraint that the global is only...

Hi Sanjay, Thanks, I saw this flag and it's definitely should be considered, but it appeared to me to be static characteristic of target platform. I'm not sure how appropriate it would be to change its value from a front-end. It says "Has", while optional flag would rather say "Uses" meaning that implementation cares about floating point exceptions. Regards, Sergey

Hi, I've been struggling with constantexprs for a bit. I'm working on a pass that transforms global variables to local variables, and in particular the GetElementPtrConstantExpr is a bit troublesome. For my transformation to properly work, a global value should only be used by Instructions, not by ConstantExprs. I was thinking to add a ConstantExpr::replaceWithInstr() virtual method,
