* Disable a fix in the previous patch, since it breaks CellSPU.Nate Begeman2008-07-291-2/+4
| | | | | | | | The CellSPU codegen is broken, but needs to be fixed before we can put this back in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54164 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | partially unroll a loop when fully unrolling would not fit under the threshold. Patch by Mikael Lepistö. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54160 91177308-0d34-0410-b5e6-96231b3b80d8
* Restructure ArgumentPromotion a bit. Instead of just having a single booleanMatthijs Kooijman2008-07-292-99/+260
| | | | | | | | | | | | | | | that says "unconditional loads from this argument are safe", we now keep track of the safety per set of indices from which loads happen. This prevents ArgPromotion from promoting loads that aren't really valid. As an added effect, this will now disregard the the type of the indices passed to a GEP, so "load GEP %A, i32 1" and "load GEP %A, i64 1" will result in a single argument, not two. This fixes PR2598, for which a testcase has been added as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54159 91177308-0d34-0410-b5e6-96231b3b80d8

* Fold the useful features of alist and alist_node into ilist, andDan Gohman2008-07-2833-815/+340
| | | | | | | | | | | | | | | | | a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54146 91177308-0d34-0410-b5e6-96231b3b80d8
