[LLVMdev] does llvm have some way to get the size of data type
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

[LLVMdev] how to add and call a function with void return value in functionpass.
Hi:
In a function pass, I tried to create a function which takes a int32 and
return void.
When I call this function with CallInst::Create and using opt, it always has
the error report:
opt: Value.cpp:189: void llvm::Value::setName(const llvm::Twine&): Assertion
`getType() != Type::getVoidTy(getContext()) && "Cannot assign a name to void
values!"' failed.

[LLVMdev] Question. about Machinefunction pass, funtion Prolog/Epilog code, stack frame
I am new to the LLVM, and need some help with this points.
1. how can we add special code for the Prolog/Epilog for some
certain functions, this should be done with machinefunction pass, rt?
2. Basically, I want to get the function stack frame, that is the size and
the initial position.
I found
int64_t llvm::MachineFrameInfo::getObjectSize ( int *ObjectIdx* )
const[inline]
