[cfe-dev] Option -mtune

[Sjoerd Meijer via cfe-dev]

Hello,

Quick question what you think we should be doing with option -mtune. Problem is that it looks like we support it because it is documented, it can be supplied on the command line, but it is silently ignored:

  // FIXME: Handle -mtune=.
  (void)Args.hasArg(options::OPT_mtune_EQ);

giving the false impression to users it is doing something is probably the worst of options we have (we get regularly questions about this).
We could simply remove it, or if this is too radical, issue a diagnostic that this is an unsupported option? Any thoughts/preferences?

Cheers,
Sjoerd.
