d2a8e14177 Fix the MLIR Vim syntax file: the keyword group was missing 2019-12-26 04:50:38 +00:00

47034c4bc5 Introduce prefetch op: affine -> std -> llvm intrinsic 
Introduce affine.prefetch: op to prefetch using a multi-dimensional
subscript on a memref; similar to affine.load but has no effect on
semantics, but only on performance.

Provide lowering through std.prefetch, llvm.prefetch and map to llvm's
prefetch instrinsic. All attributes reflected through the lowering -
locality hint, rw, and instr/data cache.

  affine.prefetch %0[%i, %j + 5], false, 3, true : memref<400x400xi32>

458ede8775 Introduce splat op + provide its LLVM lowering 
- introduce splat op in standard dialect (currently for int/float/index input
  type, output type can be vector or statically shaped tensor)
- implement LLVM lowering (when result type is 1-d vector)
- add constant folding hook for it
- while on Ops.cpp, fix some stale names
