* [CodeView] Add support for content hashing CodeView type records.Zachary Turner2017-12-058-46/+366
| | | | | | | | | Currently nothing uses this, but this at least gets the core algorithm in, and adds some test to demonstrate correctness. Differential Revision: https://reviews.llvm.org/D40736 llvm-svn: 319854
* [SelectionDAG] Don't promote the condition operand of VSELECT when promoting ↵Craig Topper2017-12-051-2/+0

* [SelectionDAG] Don't promote mask operand when widening mstore and mscatter.Craig Topper2017-12-054-37/+23
| | | | | | If the mask needs to be promoted that should occur by the legalizer detecting the mask operand needs to be promoted not as a side effect of another action. llvm-svn: 319852
* [SelectionDAG] Don't promote mask when splitting mstore.Craig Topper2017-12-051-3/+0
| | | | | | If the mask needs to be promoted it should be handled by operand promotion after the result is legalized. llvm-svn: 319851
* [SelectionDAG] Don't promote mask operands of MGATHER and MLOAD to setcc ↵Craig Topper2017-12-051-2/+10
| | | | | | | | result type while widening the result. Just widen the mask. The mask will be promoted if necessary when operands are promoted. It's possible the mask type is legal, but the setcc result type is a different. We shouldn't promote to the setcc result type unless the mask needs to be promoted. llvm-svn: 319850
* [SelectionDAG] Don't call GetWidenedVector for mask operands of MLOAD/MSTORE.Craig Topper2017-12-051-13/+6
| | | | | | GetWidenedVector does't guarantee the widened elements are zero which would break the intended behavior of the operation. llvm-svn: 319849

* [CMake] Use PRIVATE in target_link_libraries for executablesShoaib Meenai2017-12-0579-29/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently use target_link_libraries without an explicit scope specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables. Dependencies added in this way apply to both the target and its dependencies, i.e. they become part of the executable's link interface and are transitive. Transitive dependencies generally don't make sense for executables, since you wouldn't normally be linking against an executable. This also causes issues for generating install export files when using LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM library dependencies, which are currently added as interface dependencies. If clang is in the distribution components but the LLVM libraries it depends on aren't (which is a perfectly legitimate use case if the LLVM libraries are being built static and there are therefore no run-time dependencies on them), CMake will complain about the LLVM libraries not being in export set when attempting to generate the install export file for clang. This is reasonable behavior on CMake's part, and the right thing is for LLVM's build system to explicitly use PRIVATE dependencies for executables. Unfortunately, CMake doesn't allow you to mix and match the keyword and non-keyword target_link_libraries signatures for a single target; i.e., if a single call to target_link_libraries for a particular target uses one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must also be updated to use those keywords. This means we must do this change in a single shot. I also fully expect to have missed some instances; I tested by enabling all the projects in the monorepo (except dragonegg), and configuring both with and without shared libraries, on both Darwin and Linux, but I'm planning to rely on the buildbots for other configurations (since it should be pretty easy to fix those). Even after this change, we still have a lot of target_link_libraries calls that don't specify a scope keyword, mostly for shared libraries. I'm thinking about addressing those in a follow-up, but that's a separate change IMO. Differential Revision: https://reviews.llvm.org/D40823 llvm-svn: 319840

* [SafepointIRVerifier] Allow deriving pointers from unrelocated baseAnna Thomas2017-12-052-45/+271
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch allows to use derived pointers (GEPs/bitcasts) of unrelocated base pointers. We care only about the uses of these derived pointers. It is acheived by two changes: 1. When we have enough information to say if the pointer is unrelocated at some point or not, we walk all BBs to remove from their Contributions all valid defs of unrelocated pointers (GEP with unrelocated base or bitcast of unrelocated pointer). 2. When it comes to verification we just ignore instructions that were removed at stage 1. Patch by Daniil Suchkov!

* [AArch64] Do not abort if overflow check does not use EQ or NE.Joel Galenson2017-12-051-3/+2

* Enable auto-linking on WindowsSaleem Abdulrasool2017-12-051-0/+7
| | | | | | | | | | | The MSVC driver and clang do not link against the C++ runtime explicitly. Instead, they rely on the auto-linking via the pragma (through `use_ansi.h`) to link against the correct version of the C++ runtime. Attempt to do something similar here so that linking real C++ code on Windows does not require the user to explicitly specify `c++.lib` when using libc++ as a C++ runtime on windows. llvm-svn: 319816
