Out-of-line atomics implementation ways
...n. More specifically:
1. Pass to expand atomics to library helper functions calls.
These helpers test for the presence of LSE instructions and dispatch to corresponding sequence of instructions.
There are 100 helpers resulting from various combinations of instruction = { cas| swp | ldadd | ldset| ldclr| ldeor }, memory model = { relax, acq, rel, acq_rel } and size = {1, 2, 4 , 8, 16}.
I am considering two possibilities:
i. Atomic Expand pass: add new AtomicExpansionKind::OutOfLine, and if it was set by target expand atomics to RTLIB libcalls. It will require to add 100 new "standardized&quo...
