libclang on 64-bit Ubuntu treats size_t as int


We are using libclang to parse header files and post-processing the AST. On Ubuntu 16.04 64-bit with the clang+llvm 3.8 download, I am seeing size_t come out of clang_getTypeSpelling as an int, even if I supply -m64 as an arg to the compiler. This seems to work fine on macOS and Windows, both 64-bit.

Any thoughts?


Treating a type as `int` often indicates failure to #include something.
What do you get for decltype(sizeof(1)) ?

I don't expect that Clang would ever select `int` (a signed type) for its
size_t; this seems much more likely to be a library/code problem. But I
could be wrong.
