* AMDGPU: Switch barrier intrinsics to using convergentMatt Arsenault2015-12-191-2/+2
| | | | | | | | noduplicate prevents unrolling of small loops that happen to have barriers in them. If a loop has a barrier in it, it is OK to duplicate it for the unroll. llvm-svn: 256075
* Fix broken type legalization of min/maxMatt Arsenault2015-12-192-2/+20
| | | | | | | This was using an anyext when promoting the type when zext/sext is required. llvm-svn: 256074

* AMDGPU: fix overlapping copies in copyPhysRegNicolai Haehnle2015-12-191-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When copying aggregate registers within the same register class, there may be an overlap between source and destination that forces us to do the copy backwards. Do the simplest possible thing that guarantees the correct order of moves when there are overlaps, and does whatever when there is no overlap. (The last part forces some trivial adjustments to test cases.) Together with r255906, this fixes a VM fault in Unreal Elemental Demo. While at it, change the generation of kill and def flags to something that looks more reasonable. This method is used very late during compilation, so it probably doesn't matter in practice, and to be honest, I don't know if this change is actually correct because the semantics in connection with aggregate registers vs. sub-registers are not clear to me.

* [Symbolize] Improve the ownership of parsed objects.Alexey Samsonov2015-12-181-46/+45
| | | | | | | | | | | | | | | | | | This code changes the way Symbolize handles parsed binaries: now parsed OwningBinary<Binary> is not broken into (binary, memory buffer) pair, and is just stored as-is in a cache. ObjectFile components of Mach-O universal binaries are also stored explicitly in a separate cache. Additionally, this change: * simplifies the code that parses/caches binaries: it's now done in a single place, not three different functions. * makes flush() method behave as expected, and actually clear the cached parsed binaries and objects. * fixes a dangling pointer issue described in http://reviews.llvm.org/D15638 llvm-svn: 256041
* Use getEdgeProbability() instead of getEdgeWeight() in BFI and remove ↵Cong Hou2015-12-181-13/+0
| | | | | | | | | | | | | | getEdgeWeight() interfaces from MBPI. This patch removes all getEdgeWeight() interfaces from CodeGen directory. As getEdgeProbability() is a little more expensive than getEdgeWeight(), I will compose a patch soon in which BPI only stores probabilities instead of edge weights so that getEdgeProbability() will have O(1) time.

* Improve DWARFDebugFrame::parse to also handle __eh_frame.Pete Cooper2015-12-183-19/+186
| | | | | | | | | | | | | | | LLVM MC has single methods which can handle the output of EH frame and DWARF CIE's and FDE's. This code improves DWARFDebugFrame::parse to do the same for parsing. This also allows llvm-objdump to support the --dwarf=frames option which objdump supports. This option dumps the .eh_frame section using the new code in DWARFDebugFrame::parse. http://reviews.llvm.org/D15535 Reviewed by Rafael Espindola. llvm-svn: 256008

* [AArch64] Promote loads from storesJun Bum Lim2015-12-181-3/+280
| | | | | | | | | | | | | | This change promotes load instructions which directly read from stores by replacing them with mov instructions. If the store is wider than the load, the load will be replaced with a bitfield extract. For example : STRWui %W1, %X0, 1 %W0 = LDRHHui %X0, 3 becomes STRWui %W1, %X0, 1 %W0 = UBFMWri %W1, 16, 31 llvm-svn: 256004

* Handle archives with paths in the names.Rafael Espindola2015-12-181-2/+4
| | | | | | | | | | | | | | | | We always create archives with just he filename as the member name, but other archives can put a more complicated path in there. This patches handles it by computing just the filename as we do when adding a new member. If storing the path is important for some reason, we should probably have an orthogonal option for doing that and do it for both old and new members. Fixes pr25877. llvm-svn: 256001

* [X86] Use push-pop for materializing small constants under 'minsize'Hans Wennborg2015-12-175-4/+76
| | | | | | | | | | | | | Use the 3-byte (4 with REX prefix) push-pop sequence for materializing small constants. This is smaller than using a mov (5, 6 or 7 bytes depending on size and REX prefix), but it's likely to be slower, so only used for 'minsize'. This is a follow-up to r255656.

* [InstCombine] Extend peephole DSE to handle unordered atomicsPhilip Reames2015-12-171-6/+11

| | | | | | | | | | | | | | | | | | | | | | Summary: I didn't realize that we already allowed atomic load/store of pointers, it was added in 2012 by r162146. This patch updates the documentation and tightens the verifier by using DataLayout to make sure that the stored size is byte-sized and power-of-two. DataLayout is also used for integers, and while I'm here I updated the corresponding code for cmpxchg and rmw.

* [EarlyCSE] DSE of atomic unordered storesPhilip Reames2015-12-171-18/+17
| | | | | | | | | | The rules for removing trivially dead stores are a lot less complicated than loads. Since we know the later store post dominates the former and the former dominates the later, unless the former has side effects other than the actual store, we can remove it. One slightly surprising thing is that we can freely remove atomic stores, even if the later one isn't atomic. There's no guarantee the atomic one was every visible. For the moment, we don't handle DSE of ordered atomic stores. We could extend the same chain of reasoning to them, but the catch is we'd then have to model the ordering effect without a store instruction. Since our fences are a stronger than our operation orderings, simple using a fence isn't an obvious win. This arguable calls for a refinement in our fence specification, but that's (much) later work.
