Which one?

 I don't know what its name is. It was proposed by Hans Boehm, and the
Android team pointed me to this discussion on a RISC-V mailing list:

The RV64A stuff?  I don't know about android but I would find
it limiting.  Kind of like having to work with C/C++17 concurrency
support without having to resort to inline assembly on x64. I
know risc-v thinks they solved the ABA problem with lr/sc but
they haven't in all cases.
