[Openmp-commits] [PATCH] D86307: [OpenMP] Pack first-private arguments to improve efficiency of data transfer

[Jon Chesterfield via Phabricator via Openmp-commits]

JonChesterfield added a comment.

This is a good direction. Packing copies together is likely to be faster.

Things like the size limit for profitability will be target specific, suggest adding a hook to the plugin to query such things.

E.g. over pcie vs a shared memory system are likely to have different thresholds. Nvptx and amdgcn will be different too.
