llvm-6502/lib/Target/DarwinTargetAsmInfo.cpp
Chris Lattner e2b060161c Change the asmprinter to print the comment character before the
"inlineasmstart/end" strings so that the contents of the directive
are separate from the comment character.  This lets elf targets
get #APP/#NOAPP for free even if they don't use "#" as the comment
character.  This also allows hoisting the darwin stuff up to the
shared TAI class.
