[OpenMP 5.0] Codegen support to pass user-defined mapper functions to runtime

[lildmh]

Summary

This patch implements the code generation to use OpenMP 5.0 declare mapper (e.g., user-defined mapper) constructs. It looks up the proper mapper function for each map, to, or from clause that has a user-defined mapper associated, and passes them to the OpenMP runtime function.
The design slides can be found at https://github.com/lingda-li/public-sharing/blob/master/mapper_runtime_design.pptx

I would suggest to split this patch into 2 part: the first one is NFC and just makes the ompiler to use the new interfaces and the second with the new functionality for mappers.

Seems to me, with mapper you're changing the contract of this function. It is supposed to return the size in bytes, with Mapper it returns just number of elements. Bad decision. Better to convert size in bytes to number of elements in place where you need it.

Rebase and address comments

[lildmh]

I'll split the patch into 2 later

lib/CodeGen/CGOpenMPRuntime.cpp

7388 ↗

(On Diff #229200)

Yes. The reason why I did this is I found this is the single place that I can consider all situations. Otherwise, I need to divide the size by the element size in other places. Since this function has discussed all situations for the element size, I will need to duplicate the work elsewhere if I don't do it here. The latter solution is not good for code mountainous I think.

7564–7573 ↗

(On Diff #229200)

Maybe not in this patch?

8821–8822 ↗

(On Diff #229200)

Not sure where this code will be used. I guess it's still correct to add a null to the mappers here?

8953–8955 ↗

(On Diff #229200)

I saw all the other places are using CreateConstInBoundsGEP2_32 to get sizes, types, etc. So I kept it consistent here. Maybe these modifications should be in a future patch?

8956–8957 ↗

(On Diff #229200)

Again, this is to keep it consistent with previous code above?

8991–8994 ↗

(On Diff #229200)

Again, this is to keep consistent with previous code?

[ABataev]

Do we really need to set HasMapper to true unconditionally here and in other places?

clang/lib/CodeGen/CGOpenMPRuntime.h

841–842

Is this required to make it virtual?

1556

(!HasMapper || MappersArray)?

lib/CodeGen/CGOpenMPRuntime.cpp

7388 ↗

(On Diff #229200)

Changing the original function contract is also not the best solution. Better to introduce the new function. If some of the code can be reused, need to factor out the common code and reuse it in the old function and the new one.

7388 ↗

(On Diff #229200)

Also, additional question. Does it mean that we pass to the runtime functions different values in different situations: in one case we pass size in bytes, with mappers - number of elements? If so, it is a very bad idea caused by bad design. We need to pass either size in bytes, or number of elements in this argument.

7564–7573 ↗

(On Diff #229200)

It is better to make it in this patch or make a separate patch and commit it before this one. We try to resolve this as soon as possible.

8821–8822 ↗

(On Diff #229200)

I mean, that in general, it would be good to see here some kind of an assertion. Almost all situations must be resolved in Sema.

8953–8955 ↗

(On Diff #229200)

Some of the modifications were made before we had these new functions. Now, we have the new ones and if we can use it, better to switch to the new safer versions.

8956–8957 ↗

(On Diff #229200)

No need to rely on the old code if can make something cleaner and better. Cast Mfunc to voidptr in the if statement and no need to make some extra casts later.

8991–8994 ↗

(On Diff #229200)

Same, use the best code if we can use it.

[lildmh]

Alexey, thanks for the review

clang/include/clang/AST/OpenMPClause.h

4918

For map, to, and from clauses, they can have mappers, so it's set to true. For is_device_ptr and use_device_ptr, it's set to false.

lib/CodeGen/CGOpenMPRuntime.cpp

7388 ↗

(On Diff #229200)

Yes, the current design is like this. Let me see how to make it better

8821–8822 ↗

(On Diff #229200)

Okay, I guess it's not the work of this patch

[ABataev]

clang/include/clang/AST/OpenMPClause.h

4918

So, it completely depends on the clause kind, right? If so, can we just remove it and rely on the clause kind?

[lildmh]

clang/include/clang/AST/OpenMPClause.h

4918

This is used in OMPMappableExprListClause which is inherited by all these clauses. Do you mean to check the template type there to get the clause kind?

[ABataev]

clang/include/clang/AST/OpenMPClause.h

4918

I see. I think it is better to rename it to ClauseSupportsMapper (or something like this) and make it const. Currently, it is confusing. I thought that this flag shows the use of the mapper in the clause.

[lildmh]

clang/include/clang/AST/OpenMPClause.h

4918

Ok, will do that

[lildmh]

Address Alexey's comments to change mapper function size and refactor code

[ABataev]

Looks much better in general, need to resolve last one issue with number of elements/size and you're ready.

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

So, we're still going to use number of elements for mappers? And pass it in the same parameter that in other cases is used as size in bytes? If so, point to it explicitly in the review for the runtime part so all are informed about it.

9295

getOrEmitUserDefinedMapperFunc?

[lildmh]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

From interface, the mapper function uses size in bytes now. Inside, it needs number of elements to iterate through all elements. This has no impact on the runtime part, since it looks like normal mapping from the interface. All conversion happens inside the mapper function which is completely generated by the compiler.

9295

I guess getUserDefinedMapperFunc is a better name? Because the user uses this function to get the mapper function. Emitting a mapper function is a side effect.

[ABataev]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Ok. Then why do we need to convert size in bytes to number of elements here?

9295

I meant something like getOrCreate... but it is up to you.

[lildmh]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

This is used to 1) see if we are going to map an array of elements with mapper, and 2) iterate all to map them individually.

9295

Okay, sounds good

[ABataev]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Could you point where we have this kind of analysis here? Because I don't see anything affected by this change in the patch.

[lildmh]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9032

Size is used to compute the last element position, which is used as the loop boundary.

9258

Size is used to see if this is an array.

[ABataev]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Is this a bug fix in the previous implementation?

[lildmh]

Change the function name

[lildmh]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

The previous implementation assumes the size is the number of elements, and it works correctly under that assumption. Since we change the meaning of size here, I add this line of code so the previous implementation can work correctly in the new assumption that the size is the size in bytes.

[ABataev]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Ah, got it. Then, in general, looks good. Please, split the patches in to, possibly, 2 NFC (one with using of the new functions + another one for aggregating too many params into records) + another one with the new functionality.

[lildmh]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Okay, will do that. What do you think need to be done for the runtime patch D68100?

[ABataev]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Address comments and rebase, I think

[lildmh]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

The only left comment is to split it into 2 patches, I think.

[ABataev]

clang/lib/CodeGen/CGOpenMPRuntime.cpp

9030–9031

Do it.

[lildmh]

@grokos Could you upstream this patch and the runtime patch neck to neck? Upstreaming one of them will break the OpenMP offloading. It will be nice if you can test this patch locally with the runtime patch. Thanks

[grokos]

I tried to build clang with this patch and I get errors like:

Where are these OMPRTL___tgt_ symbols defined?
