gpu-to-llvm-spv.mlir	[mlir][LLVM] Switch undef for poison for uninitialized values (#125629) LLVM itself is generally moving away from using undef and towards using poison, to the point of having a lint that caches new uses of undef in tests. In order to not trip the lint on new patterns and to conform to the evolution of LLVM - Rename valious ::undef() methods on StructBuilder subclasses to ::poison() - Audit the uses of UndefOp in the MLIR libraries and replace almost all of them with PoisonOp The remaining uses of undef are initializing uninitialized memrefs, explicit conversions to undef from SPIR-V, and a few cases in AMDGPUToROCDL where usage like %v = insertelement <M x iN> undef, iN %v, i32 0 %arg = bitcast <M x iN> %v to i(M * N) is used to handle "i32" arguments that are are really packed vectors of smaller types that won't always be fully initialized.	1 年前
printf.mlir	[MLIR][GPU] Generalize gpu.printf op lowering to LLVM call pattern. (#164297) Existing pattern for lowering gpu.printf op to LLVM call uses fixed function name and calling convention. Those two should be exposed as pass option to allow supporting Intel Compute Runtime for GPU. Also adds gpu.printf op pattern to GPU to LLVMSPV pass. It may appear out of place, but integration test is added to XeVM integration test as that is the current best folder for testing with Intel Compute Runtime. Test should be moved in the future if a better test folder is added.	10 个月前
