* [WebAssembly] Add -m:e to the target triple.Dan Gohman2016-01-0747-51/+52
| | | | | | | This enables ELF-style name mangling, which primarily means using ".L" for private symbols. llvm-svn: 257020
* [Linker] Also treat a DIImportedEntity scope DISubprogram as needed.Ahmed Bougacha2016-01-072-15/+25
| | | | | | | | | Follow-up to r257000: DIImportedEntity can reach a DISubprogram via its entity, but also via its scope. Handle the latter case as well. PR26037. llvm-svn: 257019
* [RS4GC] Add an option to suppress vector splittingPhilip Reames2016-01-071-9/+20
| | | | | | At the moment, this is essentially a diangostic option so that I can start collecting failing test cases, but we will eventually migrate to removing the vector splitting code entirely. llvm-svn: 257015

* [ShrinkWrapping] Give up on irreducible CFGs.Quentin Colombet2016-01-072-0/+108
| | | | | | | | | | | We need to know whether or not a given basic block is in a loop for the analysis to be correct. Loop information may be incomplete on irreducible CFGs, therefore we may generate incorrect code if we use it in those situations. This fixes PR25988. llvm-svn: 257012
* tools/llvm-config: improve shared library supportAndrew Wilkins2016-01-076-50/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: r252532 added support for reporting the monolithic library when LLVM_BUILD_LLVM_DYLIB is used. This would only be done if the individual components were not found, and the dynamic library is found. This diff extends this as follows: - If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared library, even if all component libraries exist. - Two flags, --link-shared and --link-static are introduced to provide explicit guidance. If --link-shared is passed and the shared library does not exist, an error results. Additionally, changed the expected shared library names from (e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an installation (and then only in CMake builds I think?), and not in the build tree; this breaks usage of llvm-config during builds, e.g. by llvm-go.

* Always treat DISubprogram reached by DIImportedEntity as needed.Teresa Johnson2016-01-073-1/+64
| | | | | | | | | | It is illegal to have a null entity in a DIImportedEntity, so we must link in a DISubprogram metadata node referenced by one, even if the associated function is not linked in or inlined anywhere. Fixes PR26037. llvm-svn: 257000

* [X86] Determine if target shuffle can contain zero elementsSimon Pilgrim2016-01-061-15/+17
| | | | | | | | | | | | | | getTargetShuffleMask may return shuffle masks with SM_SentinelZero (-2) values (currently just for PSHUFB but VPERM2X128 as well with this patch). Although some calling functions can make use of this (mainly for shuffle combining), others can not and their inclusion makes shuffle mask comparisons more difficult. This patch adds a flag to getTargetShuffleMask to indicate if the calling function can't handle SM_SentinelZero; getTargetShuffleMask will then return false if it occurs to make handling much easier. I've tidied up some uses of getTargetShuffleMask to better indicate what is going on - more could be done but at present I don't have test cases to demonstrate it. Some upcoming patches will make use of this to both support more uses where SM_SentinelZero is not permitted (e.g. combineShuffleToAddSub), and also will allow us to add INSERTPS support to getTargetShuffleMask as part of better zero handling discussed in D14261.

* [Bitcode] Remove superflous compatibility testsVedant Kumar2016-01-061-4/+0
| | | | | | | | With r256990, bogner introduced comprehensive tests for constant arrays and vectors. We no longer need the existing ones because they are redundant. llvm-svn: 256991
* Bitcode: Move these tests into compatibility.llJustin Bogner2016-01-062-32/+30
| | | | | | | | I added a couple of tests in r256982, but vedantk suggested that they fit better into compatibility.ll, since they could catch format breaks later on there. llvm-svn: 256990

* Bitcode: Fix reading and writing of ConstantDataVectors of halfsJustin Bogner2016-01-063-23/+47
| | | | | | | | | | | | In r254991 I allowed ConstantDataVectors to contain elements of HalfTy, but I missed updating the bitcode reader and writer to handle this, so now we crash if we try to emit bitcode on programs that have constant vectors of half. This fixes the issue and adds test coverage for reading and writing constant sequences in bitcode. llvm-svn: 256982

* [SplitLandingPadPredecessors] Create a PHINode for the original landingpad ↵Chen Li2016-01-062-5/+44
| | | | | | | | | | | | | | only if it has some uses Summary: This patch adds a check in SplitLandingPadPredecessors to see if the original landingpad instruction has any uses. If not, we don't need to create a PHINode for it in the joint block since it's gonna be a dead code anyway. The motivation for this patch is that we found a bug that SplitLandingPadPredecessors created a PHINode of token type landingpad, which failed the verifier since PHINode can not be token type. However, the created PHINode will never be used in our code pattern. This patch will workaround this bug, and we might add supports in SplitLandingPadPredecessors to handle token type landingpad with uses in the future.

* Consolidate MemRefs handling from BranchFolding and correct latent bugPhilip Reames2016-01-062-18/+35
| | | | | | | | | | | | Move the logic from BranchFolding to use the shared infrastructure for merging MMOs introduced in 256909. This has the effect of making BranchFolding more capable. In the process, fix a latent bug. The existing handling for merging didn't handle the case where one of the instructions being merged had overflowed and dropped MemRefs. This was a latent bug in the places the code was commoned from, but potentially reachable in BranchFolding. Once this is in, we're left with a single place to consider implementing MMO unique-ing as proposed in http://reviews.llvm.org/D15230.

* [WinEH] Remove calculateCatchReturnSuccessorColorsDavid Majnemer2016-01-064-28/+9
| | | | | | | | | | | | | | The functionality that calculateCatchReturnSuccessorColors provides was once non-trivial: it was a computation layered on top of funclet coloring. These days, LLVM IR directly encodes what calculateCatchReturnSuccessorColors computed, obsoleting the need for it. No functionality change is intended. llvm-svn: 256965

* [X86] Correctly model TLS calls w.r.t. frame requirements.Quentin Colombet2016-01-063-1/+53

* Make WinCOFFObjectWriter.cpp's timestamp writing not use ENABLE_TIMESTAMPSNico Weber2016-01-065-13/+31
| | | | | | | | | | | | | | | | | | | | | LLVM_ENABLE_TIMESTAMPS controls if timestamps are embedded into llvm's binaries. Turning it off is useful for deterministic builds. r246905 made it so that the define suddenly also controls if the binaries that the llvm binaries _create_ embed timestamps or not – but this shouldn't be a configure-time option. r256203/r256204 added a driver option to toggle this on and off, so this patch now passes this driver option in LLVM_ENABLE_TIMESTAMPS builds so that if LLVM_ENABLE_TIMESTAMPS is set, the build of LLVM is deterministic – but the built clang can still write timestamps into other executables when requested. This also allows removing some of the test machinery added in r292012 to work around this problem. See PR24740 for background. http://reviews.llvm.org/D15783 llvm-svn: 256958

Some users of FindIDom() check one error condition, while others check the other. Change it to always return nullptr on failure. This fixes PR26004.

The call to adjustChainDeps() must be done after the call to addChainDependency() in order to process the SU added to the RejectMemNodes list to create memory dependencies for it.
