* Allow linking multiple bitcode files.Artem Belevich2015-10-279-67/+124
| | | | | | | | | | | | | | | | | | Linking options for particular file depend on the option that specifies the file. Currently there are two: * -mlink-bitcode-file links in complete content of the specified file. * -mlink-cuda-bitcode links in only the symbols needed by current TU. Linked symbols are internalized. This bitcode linking mode is used to link device-specific bitcode provided by CUDA. Files are linked in order they are specified on command line. -mlink-cuda-bitcode replaces -fcuda-uses-libdevice flag. Differential Revision: http://reviews.llvm.org/D13913 llvm-svn: 251427
* Include <cstdio> to fix build errors.Hafiz Abid Qadeer2015-10-271-0/+2

* [SLP] Try a bit harder to find reduction PHIsCharlie Turner2015-10-272-5/+117
| | | | | | | | | | | | | | | Summary: Currently, when the SLP vectorizer considers whether a phi is part of a reduction, it dismisses phi's whose incoming blocks are not the same as the block containing the phi. For the patterns I'm looking at, extending this rule to allow phis whose incoming block is a containing loop latch allows me to vectorize certain workloads. There is no significant compile-time impact, and combined with D13949, no performance improvement measured in ARM/AArch64 in any of SPEC2000, SPEC2006 or LNT.

* [SLP] Treat SelectInsts as reduction values.Charlie Turner2015-10-272-6/+80
| | | | | | | | | | | | | | | Summary: Certain workloads, in particular sum-of-absdiff loops, can be vectorized using SLP if it can treat select instructions as reduction values. The test case is a bit awkward. The AArch64 cost model needs some tuning to not be so pessimistic about selects. I've had to tweak the SLP threshold here.

* Fix SamplePGO segfault when debug info is missing.Diego Novillo2015-10-273-2/+45
| | | | | | | | | | When emitting a remark for a conditional branch annotation, the remark uses the line location information of the conditional branch in the message. In some cases, that information is unavailable and the optimization would segfaul. I'm still not sure whether this is a bug or WAI, but the optimizer should not die because of this. llvm-svn: 251420

| | | | | | | | | | | | | The existing behavior was correct on Darwin, which is probably the platform it was written for. Before this change, we would rewrite "align 8" to ".align 3" and then fail to make it through the integrated assembler because 3 is not a power of 2.

* Prefer ranlib mode over ar mode.Ed Schouten2015-10-271-2/+2
| | | | | | | | | | | | | | | | | For CloudABI's toolchain I have a symlink that goes from <target>-ar and <target>-ranlib to LLVM's ar binary, to mimick GNU Binutils' naming scheme. The problem is that if we're targetting ARM64, the name of the ranlib executable is aarch64-unknown-cloudabi-ranlib. This already contains the string "ar". Let's move the "ranlib" test above the "ar" test. It's not that likely that we're going to see operating systems or harwdare architectures that are called "ranlib".

| | | | | | | | | | | | | | | | | | | libLLVM-C on darwin to cover the C API needs. Summary: We've had a lot of discussion in the past about the meaningful and useful default behaviors for the llvm-shlib tool. The original implementation was heavily geared toward Apple's use, and I think that was wrong. This patch seeks to correct that. I've removed the LLVM_DYLIB_EXPORT_ALL variable and made libLLVM export everything by default. I've also added a new target that is only built on Darwin for libLLVM-C as a library that re-exports the LLVM-C API. This library is not built on Linux because ELF doesn't support re-export libraries in the same way MachO does.

* clang-format: Add an additional value to AlignAfterOpenBracket: AlwaysBreak.Daniel Jasper2015-10-278-87/+179
| | | | | | | | | | | | | | | | | | | | Summary: If this option is set, clang-format will always insert a line wrap, e.g. before the first parameter of a function call unless all parameters fit on the same line. This obviates the need to make a decision on the alignment itself. Use this style for Google's JavaScript style and add some minor tweaks to correctly handle nested blocks etc. with it.

* Deprecate -m/+m dotest options in favor of test categoriesPavel Labath2015-10-2723-171/+29
| | | | | | | | | | | | | | | | | | | Summary: This change deprecates -m/+m dotest options (the options are still recognized but they print an error message pointing to the new options) and adds a new lldb-mi test category instead. To just run lldb-mi tests, use '-G lldb-mi'. To skip lldb-mi tests, use '--skip-category lldb-mi'. All lldb-mi tests are marked as such using the getCategories method on the base MiTestCaseBase class and the @lldbmi_test decorator is not needed. In case one still needs to annotate a specific test function as an lldb-mi test, one can use the @add_test_categories(['lldb-mi']) decorator to achieve that.

* Fix race condition in process resumePavel Labath2015-10-272-2/+7
| | | | | | | | | | | | | | | | | | Summary: Gdb-remote's async thread sent out the eBroadcastBitRunPacketSent message *before* actually sending out the continue packet. Since it's this message the actually triggers the public state transition, it could happen (and it did happen in TestAttachResume, which does an "process interrupt" right after a continue) that we attempt to stop the inferior before it was actually started (which obviously did not end well). This fixes the problem by moving the broadcast after the packet was actually sent. Reviewers: clayborg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D14083 llvm-svn: 251399

* [ValueTracking] Don't special case wrapped ConstantRanges; NFCISanjoy Das2015-10-271-3/+1
| | | | | | | | | | | | | | | | | | | Use `getUnsignedMax` directly instead of special casing a wrapped ConstantRange. The previous code would have been "buggy" (and this would have been a semantic change) if LLVM allowed !range metadata to denote full ranges. E.g. in %val = load i1, i1* %ptr, !range !{i1 1, i1 1} ;; == full set ValueTracking would conclude that the high bit (IOW the only bit) in %val was zero. Since !range metadata does not allow empty or full ranges, this change is just a minor stylistic improvement. llvm-svn: 251380
