This is mostly useful with containers or other collections of uniquely owned data in C++98 where they *might* copy. With C++11 we can likely remove this in favor of move-only types and containers wrapped around those types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194315 91177308-0d34-0410-b5e6-96231b3b80d8

* [Stackmap] Materialize the jump address within the patchpoint noop slide.Juergen Ributzka2013-11-099-57/+86
| | | | | | | | | | | | | | | This patch moves the jump address materialization inside the noop slide. This enables patching of the materialization itself or its complete removal. This patch also adds the ability to define scratch registers that can be used safely by the code called from the patchpoint intrinsic. At least one scratch register is required, because that one is used for the materialization of the jump address. This patch depends on D2009.

* Rewrite the PBQP graph data structure.Lang Hames2013-11-097-418/+448
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new graph structure replaces the node and edge linked lists with vectors. Free lists (well, free vectors) are used for fast insertion/deletion. The ultimate aim is to make PBQP graphs cheap to clone. The motivation is that the PBQP solver destructively consumes input graphs while computing a solution, forcing the graph to be fully reconstructed for each round of PBQP. This imposes a high cost on large functions, which often require several rounds of solving/spilling to find a final register allocation. If we can cheaply clone the PBQP graph and incrementally update it between rounds then hopefully we can reduce this cost. Further, once we begin pooling matrix/vector values (future work), we can cache some PBQP solver metadata and share it between cloned graphs, allowing the PBQP solver to re-use some of the computation done in earlier rounds. For now this is just a data structure update. The allocator and solver still use the graph the same way as before, fully reconstructing it between each round. I expect no material change from this update, although it may change the iteration order of the nodes, causing ties in the solver to break in different directions, and this could perturb the generated allocations (hopefully in a completely benign way). Thanks very much to Arnaud Allard de Grandmaison for encouraging me to get back to work on this, and for a lot of discussion and many useful PBQP test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194300 91177308-0d34-0410-b5e6-96231b3b80d8
* [Stackmap] Add AnyReg calling convention support for patchpoint intrinsic.Juergen Ributzka2013-11-0818-51/+504
| | | | | | | | | | | | | | The idea of the AnyReg Calling Convention is to provide the call arguments in registers, but not to force them to be placed in a paticular order into a specified set of registers. Instead it is up tp the register allocator to assign any register as it sees fit. The same applies to the return value (if applicable).

* ARM: fold prologue/epilogue sp updates into push/pop for code sizeTim Northover2013-11-085-32/+292
| | | | | | | | | | | | | | | | | | ARM prologues usually look like: push {r7, lr} sub sp, sp, #4 If code size is extremely important, this can be optimised to the single instruction: push {r6, r7, lr} where we don't actually care about the contents of r6, but pushing it subtracts 4 from sp as a side effect. This should implement such a conversion, predicated on the "minsize" function attribute (-Oz) since I've yet to find any code it actually makes faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194264 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Consider a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 0) If we proceeded to GEP the aforementioned object by 8, would form a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 8) Note that we would go through the first array member, causing an out-of-bounds accesses. This is problematic because we might get fooled if we are trying to evaluate loads using this GEP, for example, based off of an object with a constant initializer where the array is zero.
