[OpenMP] Fix declare simd use on in-class member template function

2022-05-13T15:24:55+00:00

Return the Decl when parsing the template member declaration so the
'omp declare simd' pragma can be applied to it. Previously a nullptr
was returned causing an error applying the pragma.

Fixes #52700.

[OpenMP] Fix mangling for linear parameters with negative stride

2022-05-11T21:02:09+00:00

The 'n' character is used in place of '-' in the mangled name.

[OpenMP] Fix mangling for linear modifiers with variable stride

2022-05-10T21:12:44+00:00

This adds support for variable stride with the val, uval, and ref linear
modifiers.  Previously only the no modifer type ls was supported.

  val  -> Ls
  uval -> Us
  ref  -> Rs

[OpenMP] Add mangling support for linear modifiers (ref,uval,val)

2022-05-10T16:56:55+00:00

Add mangling for linear parameters specified with ref, uval, and val
for 'omp declare simd' vector functions.

Add missing stride for linear this parameters.

Eliminate extra set of simd variant function attribute.

2022-03-24T20:27:28+00:00

Current clang generates extra set of simd variant function attribute
with extra 'v' encoding.
For example:
_ZGVbN2v__Z5add_1Pf vs _ZGVbN2vv__Z5add_1Pf
The problem is due to declaration of ParamAttrs following:
    llvm::SmallVector ParamAttrs(ParamPositions.size());
where ParamPositions.size() is grown after following assignment:
    Pos = ParamPositions[PVD];
So the PVD is not find in ParamPositions.

The problem is ParamPositions need to set for each FD decl. To fix this

Move ParamPositions's init inside while loop for each FD.

[clang][OpenMP] Fix mangling of linear parameters.

2020-05-01T21:19:00+00:00

Summary:
The linear parameter token in the mangling function must be multiplied
by the pointee size in bytes when the parameter is a pointer.

[OPENMP] Scan all redeclarations looking for `declare simd` attribute.

2018-03-02T18:07:00+00:00

Patch fixes the problem with the functions marked as `declare simd`. If
the canonical declaration does not have associated `declare simd`
construct, we may not generate required code even if other
redeclarations are marked as `declare simd`.

[OPENMP] Support for -fopenmp-simd option with compilation of simd loops

Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.

Previously the attributes were emitted only for function definitions.
Patch adds emission of the attributes for function declarations.
