--- Comment #3 from Ben Longbons <b.r.longbons at gmail dot com> --- What I'm trying to do is: * parse some source code from a new language I'm developing. * Emit that to machine code via some backend (C, GCCJIT, LLVM, firm, etc.) * Also emit a header file so that the library is callable from C code. Doing this requires knowing what the underlying type was, in order to have compatible function declarations. In future I suspect it will also be useful for C++-compatible mangling, which is also used for __attribute__((overloaded)). Functions to get the size/align of any given primitive type would also be very useful. Dealing with all the edge-cases with cross-compiling is hard, especially when the target supports multilib ... even if target-gcc exists, it might not be the same version, and in general (if the preprocessor doesn't have a way to emit that info) you can only get 1 bit of information out per fork+exec. Enumerating possible target info is already way too hard in general, e.g. I can't even find a way to get the current -m32 or -mx32 target names ... with clang at least I can inspect the output of `clang -m32 -x c - -S -emit-llvm -o - <<< ''`
