* The hasMemory argument is irrelevant to how the argumentDale Johannesen2010-06-251-2/+2
| | | | | | | | | | | for an "i" constraint should get lowered; PR 6309. While this argument was passed around a lot, this is the only place it was used, so it goes away from a lot of other places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106893 91177308-0d34-0410-b5e6-96231b3b80d8

* More changes for non-top-down fast-isel.Dan Gohman2010-06-211-11/+49
| | | | | | | | | | | Split the code for materializing a value out of SelectionDAGBuilder::getValue into a helper function, so that it can be used in other ways. Add a new getNonRegisterValue function which uses it, for use in code which doesn't want a CopyFromReg even when FuncMap.ValueMap already has an entry for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106422 91177308-0d34-0410-b5e6-96231b3b80d8
