Toy	[mlir][CSE] Remove duplicated operations with MemRead side-effect This patch enhances the CSE pass to deal with simple cases of duplicated operations with MemoryEffects. It allows the CSE pass to remove safely duplicate operations with the MemoryEffects::Read that have no other side-effecting operations in between. Other MemoryEffects::Read operation are allowed. The use case is pretty simple so far so we can build on top of it to add more features. This patch is also meant to avoid a dedicated CSE pass in FIR and was brought together afetr discussion on https://reviews.llvm.org/D112711. It does not currently cover the full range of use cases described in https://reviews.llvm.org/D112711 but the idea is to gradually enhance the MLIR CSE pass to handle common use cases that can be used by other dialects. This patch takes advantage of the new CSE capabilities in Fir. Reviewed By: mehdi_amini, rriddle, schweitz Differential Revision: https://reviews.llvm.org/D122801	4 年前
standalone	[mlir] Tunnel LLVM_USE_LINKER through to the standalone example build. When building in debug mode, the link time of the standalone sample is excessive, taking upwards of a minute if using BFD. This at least allows lld to be used if the main invocation was configured that way. On my machine, this gets a standalone test that requires a relink to run in ~13s for Debug mode. This is still a lot, but better than it was. I think we may want to do something about this test: it adds a lot of latency to a normal compile/test cycle and requires a bunch of arg fiddling to exclude. I think we may end up wanting a check-mlir-heavy target that can be used just prior to submit, and then make check-mlir just run unit/lite tests. More just thoughts for the future (none of that is done here). Reviewed By: bondhugula, mehdi_amini Differential Revision: https://reviews.llvm.org/D126585	4 年前
