Attachment: Move the inline assembly to a asm file

When doing LTO the liker has to know all the undefined symbols in order to decide what it can drop. Since LTO happens at the IL level, undefined references in inline assembly are not seem.

Since PrepareAndDispatch is only referenced from inline assembly, the linker thinks it can be dropped.

Attachment: updated patch

Updated to handle the reprocessing correctly. It is not looking a lot better than the "-Wl,-u" hack :-(

I managed to get LLVM to parse the inline assembly when doing LTO.
