* 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. See the following discussion for context and upcoming changes to add floating-point and vector atomics: https://groups.google.com/forum/#!topic/llvm-dev/Nh0P_E3CRoo/discussion Reviewers: reames Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D15512 llvm-svn: 255931

* Fix delinearization of fortran arraysRoman Gareev2015-12-172-2/+42
| | | | | | | | | | | | | | | The patch fixes Bug 25759 produced by inappropriate handling of unsigned maximum SCEV expressions by SCEVRemoveMax. Without a fix, we get an infinite loop and a segmentation fault, if we try to process, for example, '((-1 + (-1 * %b1)) umax {(-1 + (-1 * %yStart)),+,-1}<%.preheader>)'. It also fixes a potential issue related to signed maximum SCEV expressions.

* [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.

* [CUDA] Make vtable construction aware of host/device side of CUDA compilation.Artem Belevich2015-12-173-0/+94
| | | | | | | | | | | | | | | | | | | C++ emits vtables for classes that have key function present in the current TU. While we compile CUDA the fact that key function was found in this TU does not mean that we are going to generate code for it. E.g. vtable for a class with host-only methods should not (and can not) be generated on device side, because we'll never generate code for them during device-side compilation. This patch adds an extra CUDA-specific check during key method computation and filters out potential key methods that are not suitable for this side of CUDA compilation. When we codegen vtable, entries for unsuitable methods are set to null. Differential Revision: http://reviews.llvm.org/D15309 llvm-svn: 255911

* [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...

* ScopGraphPrinter: Only show functions that contain at least one scopTobias Grosser2015-12-171-5/+11
| | | | | | | | | | | | | | When running 'clang -O3 -mllvm -polly -mllvm -polly-show' we now only show the CFGs of functions with at least one detected scop. For larger files/projects this reduces the number of graphs printed significantly and is likely what developers want to see. The new option -polly-view-all enforces all graphs to be printed and the exiting option -poll-view-only limites the graph printing to functions that match a certain pattern. This patch requires https://llvm.org/svn/llvm-project/llvm/trunk@255889 (and vice versa) to compile correctly. llvm-svn: 255891

| | | | | | | | | | @indntpoff is similar to @gotntpoff, but for use in position dependent code.

Otherwise the next 64 bits holds the length, and this is a 64-bit DWARF format. This is like .debug_frame." (http://www.airs.com/blog/archives/460), that also consistent with spec (https://refspecs.linuxfoundation.org/LSB_3.0.0/LSB-PDA/LSB-PDA/ehframechpt.html).

* Add AccessModifierOffset to clang-format stylePavel Labath2015-12-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | Summary: As we override the indent option of the LLVM style, we need to override the access modifier offset as well. Otherwise, classes will be formatted like such class A { public: int foo; }; which is not used anywhere in LLDB. This option makes clang-format style more similar to LLDB and brings it closer to the original intention of LLVM style, which was to not indent access modifiers.
