entry:

On x86, if the only use of a i64 load is a i64 store, generate a pair of double load and store instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66776 91177308-0d34-0410-b5e6-96231b3b80d8 2009-03-12 05:59:15 +00:00			`; RUN: llvm-as < %s \| llc -march=x86-64 \| grep {movq.*(%rsi), %rax}`
