[PATCH] OpenCL: Add new types for OpenCL 2.0

Wed Jun 17 06:47:02 PDT 2015

I think there are still lines that are too long (especially in SemaType.cpp). Have you run clang-format on your changes?

Otherwise, no further comments from my side.

There were a couple lines with > 80 columns, and this new patch version fixes them.

Drive by review here.

I was making sure there was debug info support for the bits, thanks for adding it though I'm not seeing any tests ;)

I'm pretty sure you have some 80-column violations and other formatting things, could you clang-format your patch?

Thanks!

Awesome, thanks for the tips.

CodeGen tests looks good!

Regarding the extension, could you diagnose it during the type checking instead. That way it will be cover all cases. You can look at the CL2.0 atomic type implementation in SemaType.cpp ConvertDeclSpecToType. Also please reuse the same error err_type_requires_extension instead of adding the new one. Please, add Sema test demonstating the error handling works correctly.

Thanks,
Anastasia

Ok, found out the right place to diagnose the extension and added the tests.
I am not particularly convinced that was the best way to do it; comments welcome.

Actually, I spoke too soon - I found a test with -cl-std=CL2.0. I missed that.

The codegen test would imply adding a -cl-std=2.0 option to Clang, which it currently does not have. This is because the types should only be recognised if the CL 2.0 standard is explicitly asked for (the default is to operate on 1.2 mode). Adding that option is a peripheral issue. I've added the types on the header test under the appropriate "#if defined" but when I tried to do the same on the .cl file, I found out that the test parser does not recognise the preprocessor macro and therefore was causing the test to (incorrectly) fail. As such, I reverted the test.

As for the AS for the other types, I copy-pasted the code from event_t. That's the reason why I'm actually using the "0". Are you suggesting I should change event_t to use something else, and by consequence the new types too? That would be a separate issue.
My guess is that these types are allocated on the stack, which by llvm convention will always be 0.

The new types are used by new builtins. I don't think there are any other special semantics to it.

I've added extension checks on the MSAA types, but I'm not sure if this is the right place. New patch attached.

Hi Pedro,

Could we also add a Codegen test? Also it would be better not to use constant directly as address space as the mapping could ideally be changed. Is there any reason why you generate pointers to private AS?

Are there any operations allowed on new types? Any semantical checks needed?

If MSAA types are part of an extension and not a part of the general standard we should ideally diagnose that extension is enabled when they are being used.

Anastasia

I keep forgetting you prefer patches sent to this mailing list.
This also adds lldb entries (fixes switch warnings).

The types are:

image2d_depth_t
image2d_array_depth_t
image2d_msaa_t
image2d_array_msaa_t
image2d_msaa_depth_t
image2d_array_msaa_depth_t
queue_t
ndrange_t
clk_event_t
reserve_id_t

let me know if something looks wrong,
Pedro
