[Openmp-dev] Port OpenMP RTL to RISC-V 64-bit Linux

[Roger Ferrer Ibáñez via Openmp-dev]

Hi Jeff,

thanks for your comment. When it comes to atomics, I did a cursory look on
the code and it seems to me that it is already using C++11 atomics mostly
everywhere. There are a few references to intrinsics as well. So I think
this part is OK already.

Kind regards,
Roger
