Nothing wrong. Clang/LLVM compiles U-Boot just fine
as far as I can tell. That's what I've been doing for months.
But I couldn't figure out how to make that work for the U-Boot port:
1) I need a cross-compiler the u-boot port can depend on.
I don't know a particularly clean way to depend on
the xdev tools that I was using before. It seemed much
easier to depend on another port.
2) Our port tree already had some basic framework for cross-GCC.
(Remember this is typically being cross-compiled for ARM
on i386 or amd64.) I had to fix that support a little to make it
work correctly, but the outline was already there.
3) I didn't see anything already in ports for cross-clang.
4) The base clang has some cross-build abilities, but
it's not really useful without ARM libc or binutils.
Is there some other approach that I overlooked?
Tim
