GlobalISel: Allow forming atomic/volatile G_ZEXTLOAD SelectionDAG has a target hook, getExtendForAtomicOps, which it uses in the computeKnownBits implementation for ATOMIC_LOAD. This is pretty ugly (as is having a separate load opcode for atomics), so instead allow making use of atomic zextload. Enable this for AArch64 since the DAG path defaults in to the zext behavior. The tablegen changes are pretty ugly, but partially helps migrate SelectionDAG from using ISD::ATOMIC_LOAD to regular ISD::LOAD with atomic memory operands. For now the DAG emitter will emit matchers for patterns which the DAG will not produce. I'm still a bit confused by the intent of the isLoad/isStore/isAtomic bits. The DAG implementation rejects trying to use any of these in combination. For now I've opted to make the isLoad checks also check isAtomic, although I think having isLoad and isAtomic set on these makes most sense. | 4 年前 | |

[globalisel][docs] Add a section about debugging with the block extractor Summary: Depends on D69644 Reviewers: rovka, volkan, arsenm Subscribers: wdng, Petar.Avramovic, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D69645 | 6 年前 | |
[globalisel][docs] Rework GMIR documentation and add an early GenericOpcode reference Summary: Rework the GMIR documentation to focus more on the end user than the implementation and tie it in to the MIR document. There was also some out-of-date information which has been removed. The quality of the GenericOpcode reference is highly variable and drops sharply as I worked through them all but we've got to start somewhere :-). It would be great if others could expand on this too as there is an awful lot to get through. Also fix a typo in the definition of G_FLOG. Previously, the comments said we had two base-2's (G_FLOG and G_FLOG2).

[globalisel][docs] Rewrite the pipeline overview Summary: Rewrite the pipeline overview to be more focused on the structure and flexibility as well as highlight the increased usefulness of MachineVerifier and increased testability resulting from the smaller incremental passes approach. The diagrams are lifted from the slides for the LLVMDev 2019 talk 'Generating Optimized Code with GlobalISel' and adapted to be readable on the white background used in the docs.
