[PATCH] D135076: [Clang] Make offloading flags accept '-' and '--'

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

There are traditionally some single-dash long options (perhaps classical Mac OS style) which conflict with short options. I think nowadays we try to avoid such single-dash short options.
(For example, GNU ld now requires all new long options to use two-dashes, after knowing the problem with `-omagic`.)

I can make a patch to make cc1 `-o` `Separate` instead of `JoinedOrSeparate`, which will hopefully solve your pain of specifying a misspelled `-offloat*` cc1 option without good diagnostics.
