[LV] Strip wrap flags from vectorized reductions

2019-12-20T12:48:53+00:00

A sequence of additions or multiplications that is known not to wrap, may wrap if it's order is changed (i.e., reassociated). Therefore when vectorizing integer sum or product reductions, their no-wrap flags need to be removed. Fixes PR43828 Patch by Denis Antrushin Differential Revision: https://reviews.llvm.org/D69563

[LV] Exclude loop-invariant inputs from scalar cost computation.

2019-07-14T20:12:36+00:00

Loop invariant operands do not need to be scalarized, as we are using the values outside the loop. We should ignore them when computing the scalarization overhead.

Improve reduction intrinsics by overloading result value.

2019-06-13T09:37:38+00:00

This patch uses the mechanism from D62995 to strengthen the definitions of the reduction intrinsics by letting the scalar result/accumulator type be overloaded from the vector element type. For example: ; The LLVM LangRef specifies that the scalar result must equal the ; vector element type, but this is not checked/enforced by LLVM. declare i32 @llvm.experimental.vector.reduce.or.i32.v4i32(<4 x i32> %a) This patch changes that into: declare i32 @llvm.experimental.vector.reduce.or.v4i32(<4 x i32> %a) Which has the type-constraint more explicit and causes LLVM to check the result type with the vector element type.

[VPLAN] Minor improvement to testing and debug messages.

2019-04-10T08:17:28+00:00

1. Use computed VF for stress testing. 2. If the computed VF does not produce vector code (VF smaller than 2), force VF to be 4. 3. Test vectorization of i64 data on AArch64 to make sure we generate VF != 4 (on X86 that was already tested on AVX).
