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

[Criswell, John T]

Look at the getABITypeSize() method (or some method with a name like that) of the TargetData class.

Note that TargetData is an LLVM analysis pass; you have to declare it as a prerequisite pass in your pass's getAnalysisUsage() method.

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
