David Green	7feafa0286	[ARM] Fix pointer offset when splitting stores from VMOVDRR We were not accounting for the pointer offset when splitting a store from a VMOVDRR node, which could lead to incorrect aliasing info. In this case it is the fneg via integer arithmetic that gives us a store->load pair that we started getting wrong. Differential Revision: https://reviews.llvm.org/D88653	2020-10-03 16:47:50 +01:00

[ARM] Fix pointer offset when splitting stores from VMOVDRR

We were not accounting for the pointer offset when splitting a store from
a VMOVDRR node, which could lead to incorrect aliasing info. In this
case it is the fneg via integer arithmetic that gives us a store->load
pair that we started getting wrong.
