Simon Pilgrim 8c4a86f790 [CodeGenPrepare] Remove unused check-prefixes 2020-11-09 13:12:39 +00:00
Clement Courbet 15488ff24b [CodeGen] Fix the computation of the alignment of split stores. 
Summary:
Right now the alignment of the lower half of a store is computed as
align/2, which fails for unaligned stores (align = 1), and is overly
pessimitic for, e.g. a 8 byte store aligned to 4 bytes.
Fixes PR44851
Fixes PR44877
