* Track IR ordering of SelectionDAG nodes 1/4.Andrew Trick2013-05-251-0/+62
| | | | | | | | Use a field in the SelectionDAGNode object to track its IR ordering. This adds fields and utility classes without changing existing interfaces or functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182701 91177308-0d34-0410-b5e6-96231b3b80d8
* Cleanup the simplify_type implementation.Rafael Espindola2013-03-271-12/+6
| | | | | | | | | | | | | | | | | | | | As far as simplify_type is concerned, there are 3 kinds of smart pointers: * const correct: A 'const MyPtr<int> &' produces a 'const int*'. A 'MyPtr<int> &' produces a 'int *'. * always const: Even a 'MyPtr<int> &' produces a 'const int*'. * no const: Even a 'const MyPtr<int> &' produces a 'int*'. This patch then does the following: * Removes the unused specializations. Since they are unused, it is hard to know which kind should be implemented. * Make sure we don't drop const. * Fix the default forwarding so that const correct pointer only need one specialization. * Simplifies the existing specializations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178147 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-2/+2
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove extra MayLoad/MayStore flags from atomic_load/store.Jakob Stoklund Olesen2012-08-281-5/+0
| | | | | | | | | | | | | | | These extra flags are not required to properly order the atomic load/store instructions. SelectionDAGBuilder chains atomics as if they were volatile, and SelectionDAG::getAtomic() sets the isVolatile bit on the memory operands of all atomic operations. The volatile bit is enough to order atomic loads and stores during and after SelectionDAG. This means we set mayLoad on atomic_load, mayStore on atomic_store, and mayLoad+mayStore on the remaining atomic read-modify-write operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162733 91177308-0d34-0410-b5e6-96231b3b80d8

* Add SelectionDAG::getTargetIndex.Jakob Stoklund Olesen2012-08-071-0/+23
| | | | | | | This adds support for TargetIndex operands during isel. The meaning of these (index, offset, flags) operands is entirely defined by the target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161453 91177308-0d34-0410-b5e6-96231b3b80d8
* Refactor the code that checks that all operands of a node are UNDEFs.Nadav Rotem2012-07-151-0/+4
| | | | | | | | | | | Add a micro-optimization to getNode of CONCAT_VECTORS when both operands are undefs. Can't find a testcase for this because VECTOR_SHUFFLE already handles undef operands, but Duncan suggested that we add this.
