I > think renaming it to getTypeSizeInBytes make sense. Many parts of LLVM are using getTypeSize as the size of an alloca. That seems to be wrong - I guess they should all be using getABITypeSize. In that case is getTypeSize useful? I don't see the point of having it be getTypeSizeInBits rounded up to a multiple of 8. In fact that...

Now that I'm working on codegen support for arbitrary precision integers (think i36 or i129), I've hit the problem of what getTypeSize and friends should return for such integers (the current implementations seem to me to be wrong). However it's not clear to me how getTypeSize and friends are defined. There seem to be several possible meanings for the size of a type (only talking
