It would also be nice if this support could be something a bit more general in LLVM, rather than specifically in clang, so that other llvm tools (e.g. llvm-objdump) could take advantage of a similar format for target description files if they need something more than just the triple argument.

Hi David,

When I posted that there wasn't a lot of enthusiasm for the approach. I 
am using it but people thought it would complicate the driver and didn't 
like the fact that a file might need to be read each time the compiler 
is invoked (it doesn't really require that a file be read, the YAML can 
be compiled in, but anyway).

I still think the approach is useful, so after I saw your post I made 
another example that makes clang a Windows cross compiler using the 
MinGW linker and libraries. I've posted it here: 
http://ellcc.org/blog/?p=23077

I like the idea of making it more general and allowing it to be used for 
other LLVM utilities.
