Comment (by dunfield):
> I wonder what `as -q -v </dev/null` gives on older versions of MacOS X
where the default `as` is still Apple's GAS.

> Does it print its own version, or does it invoke LLVM's `as`, and if so,
what does the latter give?
It's LLVM's `as` that's invoked (seen here on 10.9):
{{{
% as -v -q < /dev/null
Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"
-cc1as -triple x86_64-apple-macosx10.9.0 -filetype obj -main-file-name -
-target-cpu core2 -fdebug-compilation-dir /Users/dunfield -dwarf-debug-
producer Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn) -o
a.out -
}}}
> And does `as -v -q </dev/null` (options swapped) behave the same?
Yes, it does. The `-version` flag is not accepted in either order, but
`--version` and produces:
{{{
% as -q --version < /dev/null
Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
