I will take a look. Thanks.

This is because OpenCL sets C99 flag as being superset of it. If you check in clang/Frontend/LangStandards.def
LANGSTANDARD(opencl, "cl",
"OpenCL 1.0",
LineComment | C99 | Digraphs | HexFloat)
We should undo this change as it leaves no possibility to specify an OpenCL version during compilation apart from using the frontend option (which isn't conventional approach).

Did clang accept -std=CL2.0 before this change?
According to this diff, the only accepted option for -std= is c99 when compiling OpenCL programs.

Hi Sam,
I think this commit broke Clang.
It seems we are no longer able to pass the -std=CL2.0, which is important for the standalone Clang OpenCL users as -cl-std is frontend only option.
clang -std=CL2.0 test.cl
error: invalid argument '-std=CL2.0' not allowed with 'OpenCL'
We might have to revert or rework this bit:

New Revision: 267590
URL: http://llvm.org/viewvc/llvm-project?rev=267590&view=rev
Log:
[OpenCL] Add predefined macros.
OpenCL spec requires __OPENCL_C_VERSION__ to be defined based on -cl-std option. This patch implements that.
The patch also defines __FAST_RELAXED_MATH__ based on -cl-fast-relaxed-math option.
Also fixed a test using -std=c99 for OpenCL program. Limit allowed language standard of OpenCL to be OpenCL standards.
