* Add target flags to MachineMemOperands.Andrew Trick2013-04-271-1/+7
| | | | | | | | | | | | | | | | | | This seems to me an obvious place to allow target passes to annotate memory operations. There are plenty of bits, and I'm not aware of another good way for early target passes to propagate hints along to later passes. Target independent transforms can simply preserve them, the way they preserve the other flags. Like MachineMemOperands in general, if the target flags are lost we must still generate correct code. This has lots of uses, but I want this flexibility now to make it easier to work with the new MachineTraceMetrics analysis. MachineTraceMetrics can gather a lot of information about instructions based on the surrounding code. This information can be used to influence postRA machine passes that don't work on SSA form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180666 91177308-0d34-0410-b5e6-96231b3b80d8

* Add MachineMemOperand::isUnordered().Jakob Stoklund Olesen2012-08-291-0/+9
| | | | | | | | | | | | This means the same as LoadInst/StoreInst::isUnordered(), and implies !isVolatile(). Atomic loads and stored are also ordered, and this is the right method to check if it is safe to reorder memory operations. Ordered atomics can't be reordered wrt normal loads and stores, which is a stronger constraint than volatile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162859 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach CodeGen's version of computeMaskedBits to understand the range metadata.Rafael Espindola2012-03-311-1/+6
| | | | | | | | This is the CodeGen equivalent of r153747.

* Added invariant field to the DAG.getLoad method and changed all calls.Pete Cooper2011-11-081-1/+4
| | | | | | | When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144100 91177308-0d34-0410-b5e6-96231b3b80d8

* Improve MachineMemOperand handling.Dan Gohman2009-09-251-0/+10
| | | | | | | | | | | | | | | | | | | | | | - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8
