For the size of a type to be calculated at runtime, there is a known trick with gep. Is there any similar trick for determining the alignment of a type at runtime for target-independent IR? -------------- next part -------------- An HTML attachment was scrubbed...

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...

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
