LG, with some nits

include/clang/Driver/Options.td
1428

This flag also must be CC1Option

lib/Frontend/CompilerInvocation.cpp
2533

After some thoughts I think it is better to make true by default, because Generic mode is not completed yet.

This revision is now accepted and ready to land.Feb 28 2018, 6:26 AM

I think most other boolean options do the following:

if (Args.hasFlag(...))
  CmdArgs.push_back("...")

Is there a reason we need this differently here?

lib/Frontend/CompilerInvocation.cpp

Yes, I'd also expect all SPMD constructs to default to CUDA mode. Or is there a case where this doesn't work? If yes, that should be explained in the summary.

If you implement Jonas's suggested fix, no need to mark it as CC1Option

lib/Driver/ToolChains/Clang.cpp
3976–3977

Agree, this looks much better

Cuda mode is going to be the default for all constructs, as Generic mode is not ready yet. The codegen mode is not controlled by the construct, but by the option completely.
