New Revision: 313286
URL: http://llvm.org/viewvc/llvm-project?rev=313286&view=rev
Log:
Accept not only --foo but also -foo.
GNU ld manual says that multi-letter long option can be prefixed with
either -- or -. Therefore, we should accept not only --subsystem but
also -subsystem, for example.
There is one exception. If an option starts with "o", it should only be
prefixed with -- to avoid ambiguity with -o<filename> option.
