Yes, for that you need TargetData: http://illuvium.net/docs/doxygen/classllvm_1_1TargetData.html Reid.

Hi: just like the c function sizeof(). I would avoid the usage of the c function call, and expect something like llvm intrinsic or some class providing this functionality. Does someone have experience in this? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

I don't work much with LLVM's code generator infrastructure (I primarily do LLVM IR analysis and transforms), so I don't think I can answer your question. When working with pure LLVM IR, we use the TargetData class (http://llvm.org/doxygen/classllvm_1_1TargetData.html) to determine the size of various LLVM types. I'm not sure if it's what you want to use in the code generator.

Dear all I am trying to get the size of an LLVM pointer type. getPrimitiveSizeInBits() returns 0 for it and the documentation for isSized() suggest to use TargetData. I figured out from Kaleidoscope example that one can get a pointer to TagetData object through the execution engine but it seems to be an overkill. What is the right way to do it?

Hello, I would just like to ask if it's possible to explicitly free allocas. This is because I need to call functions that take structs of different sizes as input, (possibly inside of loops) and I would rather avoid a stack overflow. If this is not possible, an alternate solution would be for me to allocate an array of bytes larger than all the struct types I may be using, and cast that

Thanks for your help with me about the way to access type and size of Value. But, I want also know the interface for me to access the type or size of virtual registers in the SSA form. 1. I find no way to associate the virtual registers with the Value class. 2. I also tried to get the size of register nReg by: TargetRegisterClass::getSize(), where the TargetRegisterClass object is obtained by
