Dan Gohman dab249b3b7 Enable hoisting of loads from constant memory by default. In cases where ... they are lowered to instruction sequences more complex than a simple load, such that CodeGen cannot rematerialize them, a reload from a spill slot is likely to be cheaper than the complex sequence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89374 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-19 19:00:10 +00:00
