* Improve DWARFDebugFrame::parse to also handle __eh_frame.Pete Cooper2015-12-1811-305/+246
| | | | | | | | | | | | | | | 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 Lim2015-12-184-8/+951
| | | | | | | | | | | | | | 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
* [ThinLTO/LTO] Don't link in unneeded metadataTeresa Johnson2015-12-188-7/+244
| | | | | | | | | | | | | | | | | | | | Summary: Third patch split out from http://reviews.llvm.org/D14752. Only map in needed DISubroutine metadata (imported or otherwise linked in functions and other DISubroutine referenced by inlined instructions). This is supported for ThinLTO, LTO and llvm-link --only-needed, with associated tests for each one. Depends on D14838.

* Handle archives with paths in the names.Rafael Espindola2015-12-183-2/+13
| | | | | | | | | | | | | | | | 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 Wennborg2015-12-178-106/+262
| | | | | | | | | | | | | 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.

* [BranchProbability] Remove the restriction that known and unknown ↵Cong Hou2015-12-172-11/+57
| | | | | | | | | | | | | | | | | | | probabilities cannot coexist when being normalized. The current BranchProbability::normalizeProbabilities() forbids known and unknown probabilities to coexist in the list. This was once used to help capture probability exceptions but has caused some reported build failures (https://llvm.org/bugs/show_bug.cgi?id=25838). This patch removes this restriction by evenly distributing the complement of the sum of all known probabilities to unknown ones. We could still treat this as an abnormal behavior, but it is better to emit warnings in our future profile validator. Differential revision: http://reviews.llvm.org/D15548 llvm-svn: 255934
* [InstCombine] Extend peephole DSE to handle unordered atomicsPhilip Reames2015-12-172-6/+124

Key points: * We only remove unordered or simple stores. * The loads producing values consumed by dead stores don't influence whether the store is dead.

* Polish atomic pointersJF Bastien2015-12-173-50/+46
| | | | | | | | | | | | | | | | | | | | | | 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 Reames2015-12-172-18/+91
| | | | | | | | | | 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.

* [ThinLTO] Metadata linking for imported functionsTeresa Johnson2015-12-1718-74/+611
| | | | | | | | | | | | | | | | | | | | | | | Summary: Second patch split out from http://reviews.llvm.org/D14752. Maps metadata as a post-pass from each module when importing complete, suturing up final metadata to the temporary metadata left on the imported instructions. This entails saving the mapping from bitcode value id to temporary metadata in the importing pass, and from bitcode value id to final metadata during the metadata linking postpass. Depends on D14825.

* AMDGPU: Fix off-by-one in SIRegisterInfo::eliminateFrameIndexNicolai Haehnle2015-12-173-9/+10
| | | | | | | | | | | | | | | | | | | | | | Summary: The method insertNOPs expected the number of wait states to be passed as parameter, while eliminateFrameIndex passed the immediate argument for the S_NOP, leading to an off-by-one error. Rename the method to make the meaning of its parameter clearer. The number of 4 / 5 wait states (which is what the method has always _tried_ to do according to the comment) is correct according to the hardware docs. I stumbled upon this while trying to track down the cause of https://bugs.freedesktop.org/show_bug.cgi?id=93264. While clearly needed, this patch unfortunately does not fix that bug...
