[cfe-dev] clang tooling - Type sizes VS architectures

[Julian Mueller via cfe-dev]

Hi

I am wondering how one can teach his/her clang tool to consider compilation
on certain architectures?

For example, my tool gets a certain declaration's Type size like this:

sizeof_type_in_byte = ast_context.getTypeInfo(some_decl->getType()).Width/8;

I can't find a way to tell my ClangTool instance what architecture to
consider when building the ASTs.
I looked at the argumentAdjusters, specifically tried out:

Tool.appendArgumentsAdjuster(clang::tooling::getInsertArgumentAdjuster(
"-m32"));

yet, this has no effect.

Could someone elaborate on this?
Thanks!
