* [lit] Support sharding testsuites, for parallel execution.Graydon Hoare2017-01-181-0/+17
| | | | | | | | | | | | | | | | | | | | | | | Summary: This change equips lit.py with two new options, --num-shards=M and --run-shard=N (set by default from env vars LIT_NUM_SHARDS and LIT_RUN_SHARD). The options must be used together, and N must be in 1..M. Together these options effect only test selection: they partition the testsuite into M equal-sized "shards", then select only the Nth shard. They can be used in a cluster of test machines to achieve a very crude (static) form of parallelism, with minimal configuration work.

* [NVPTX] Let there be One True Way to set NVVMReflect params.Justin Lebar2017-01-151-28/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously there were three ways to inform the NVVMReflect pass whether you wanted to flush denormals to zero: * An LLVM command-line option * Parameters to the NVVMReflect constructor * Metadata on the module itself. This change removes the first two, leaving only the third. The motivation for this change, aside from simplifying things, is that we want LLVM to be aware of whether it's operating in FTZ mode, so other passes can use this information. Ideally we'd have a target-generic piece of metadata on the module. This change moves us in that direction.

* [cmake] Add LLVM_ENABLE_DIA_SDK option, and expose it in LLVMConfigMichal Gorny2017-01-021-0/+4
| | | | | | | | | | | | | | | Add an explicit LLVM_ENABLE_DIA_SDK option to control building support for DIA SDK-based debugging. Control its value to match whether DIA SDK support was found and expose it in LLVMConfig (alike LLVM_ENABLE_ZLIB). Its value is needed for LLDB to determine whether to run tests requiring DIA support. Currently it is obtained from llvm/Config/config.h; however, this file is not available for standalone builds. Following this change, LLDB will be modified to use the value from LLVMConfig. Differential Revision: https://reviews.llvm.org/D26255 llvm-svn: 290818

* Simplify format member detection in FormatVariadicPavel Labath2016-12-151-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This replaces the format member search, which was quite complicated, with a more direct approach to detecting whether a class should be formatted using the format-member method. Instead we use a special type llvm::format_adapter, which every adapter must inherit from. Then the search can be simply implemented with the is_base_of type trait. Aside from the simplification, I like this way more because it makes it more explicit that you are supposed to use this type only for adapter-like formattings, and the other approach (format_provider overloads) should be used as a default (a mistake I made when first trying to use this library). The only slight change in behaviour here is that now choose the format-adapter branch even if the format member invocation will fail to compile (e.g. because it is a non-const member function and we are passing a const adapter), whereas previously we would have gone on to search for format_providers for the type. However, I think that is actually a good thing, as it probably means the programmer did something wrong.

* Make processing @llvm.assume more efficient by using operand bundlesHal Finkel2016-12-151-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | There was an efficiency problem with how we processed @llvm.assume in ValueTracking (and other places). The AssumptionCache tracked all of the assumptions in a given function. In order to find assumptions relevant to computing known bits, etc. we searched every assumption in the function. For ValueTracking, that means that we did O(#assumes * #values) work in InstCombine and other passes (with a constant factor that can be quite large because we'd repeat this search at every level of recursion of the analysis). Several of us discussed this situation at the last developers' meeting, and this implements the discussed solution: Make the values that an assume might affect operands of the assume itself. To avoid exposing this detail to frontends and passes that need not worry about it, I've used the new operand-bundle feature to add these extra call "operands" in a way that does not affect the intrinsic's signature. I think this solution is relatively clean. InstCombine adds these extra operands based on what ValueTracking, LVI, etc. will need and then those passes need only search the users of the values under consideration. This should fix the computational-complexity problem. At this point, no passes depend on the AssumptionCache, and so I'll remove that as a follow-up change.

* IR, X86: Understand !absolute_symbol metadata on global variables.Peter Collingbourne2016-12-081-0/+19
| | | | | | | | | | | | | | | | | Summary: Attaching !absolute_symbol to a global variable does two things: 1) Marks it as an absolute symbol reference. 2) Specifies the value range of that symbol's address. Teach the X86 backend to allow absolute symbols to appear in place of immediates by extending the relocImm and mov64imm32 matchers. Start using relocImm in more places where it is legal.

* IR: Change PointerType to derive from Type rather than SequentialType.Peter Collingbourne2016-12-021-2/+2
| | | | | | | | | | | | | | | | | | | As proposed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-October/106640.html This is for a couple of reasons: - Values of type PointerType are unlike the other SequentialTypes (arrays and vectors) in that they do not hold values of the element type. By moving PointerType we can unify certain aspects of how the other SequentialTypes are handled. - PointerType will have no place in the SequentialType hierarchy once pointee types are removed, so this is a necessary step towards removing pointee types.
