* | [SystemZ] Add support for 128-bit atomic load/store/cmpxchg | Ulrich Weigand | 2017-08-04 | 1 | -0/+13 |
This adds support for the main 128-bit atomic operations, using the SystemZ instructions LPQ, STPQ, and CDSG. Generating these instructions is a bit more complex than usual since the i128 type is not legal for the back-end. Therefore, we have to hook the LowerOperationWrapper and ReplaceNodeResults TargetLowering callbacks. llvm-svn: 310094 |
