Artem Belevich	d0615a93bb	[NVPTX] Handle bitcast and ASC(101) when trying to avoid argument copy. This allows us to skip the copy in few more cases. Differential Revision: https://reviews.llvm.org/D99979	2021-04-06 13:06:00 -07:00
Artem Belevich	50c7504a93	[NVPTX] Avoid temp copy of byval kernel parameters. Avoid making a temporary copy of byval argument if all accesses are loads and therefore the pointer to the parameter can not escape. This avoids excessive global memory accesses when each kernel makes its own copy. Differential revision: https://reviews.llvm.org/D98469	2021-03-15 14:27:22 -07:00

[NVPTX] Avoid temp copy of byval kernel parameters.

Avoid making a temporary copy of byval argument if all accesses are loads and
therefore the pointer to the parameter can not escape.

This avoids excessive global memory accesses when each kernel makes its own
copy.
