[cfe-dev] [RFC][OpenCL] Allow -cl-std and other standard -cl- options in driver

[Anastasia Stulova via cfe-dev]

You should be able to pass -std=CL1.1|CL1.2|CL2.0 to the Clang driver. We have broken it lately though, but the fix is on the way: http://reviews.llvm.org/D20630

Some other options are supported too, but not called the same way i.e. -ffast-math (analogue to -cl-fast-relaxed-math).

Which options would you be interested in particular? I think we should try to avoid duplication with existing ones that are already in Clang.

The -cl options are generally a part of the OpenCL runtime API spec, but they might be useful to have for standalone compilation indeed.

Cheers,
Anastasia

Subject: [RFC][OpenCL] Allow -cl-std and other standard -cl- options in driver

cfe-dev,

Currently, -cl-std= and -cl- options are only accepted by clang compiler with -cc1, which is not convenient for OpenCL users.

Is it possible to allow these options into clang driver (without -cc1)?

Thanks,
