Francesco Petrogalli	1de214fa41	[fix][unittests][llvm] Fix running unit tests without assertions. [NFCI]	2019-12-05 03:28:19 +00:00
Francesco Petrogalli	eac93757c3	[VectorUtils] API for VFShape, update VFInfo. ... Summary: This patch introduces an API to build and modify vector shapes. The validity of a VFShape can be checked with the `hasValidParameterList` method, which is also run in an assertion each time a VFShape is modified. The field VFISAKind has been moved to VFInfo under the assumption that different ISAs can map to the same VFShape (as it can be in the case of vector extensions with the same registers size, for example AVX and AVX2).

Sanjay Patel	40e3bdf876	[Analysis] add isSplatValue() for vectors in IR ... We have the related getSplatValue() already in IR (see code just above the proposed addition). But sometimes we only need to know that the value is a splat rather than capture the splatted scalar value. Also, we have an isSplatValue() function already in SDAG. Motivation - recent bugs that would potentially benefit from improved splat analysis in IR: https://bugs.llvm.org/show_bug.cgi?id=37428 https://bugs.llvm.org/show_bug.cgi?id=42174 Differential Revision: https://reviews.llvm.org/D63138 llvm-svn: 363106	2019-06-11 22:25:18 +00:00
