* [SelectionDAG] Optimization of BITREVERSE legalization for power-of-2 ↵Simon Pilgrim2016-07-221-3/+46
| | | | | | | | | | | | | | integer scalar/vector types An extension of D19978, this patch replaces the default BITREVERSE evaluation of individual bit masks+shifts with block mask+shifts when we have integer elements of power-of-2 bits in size. After calling BSWAP to reverse the order of the constituent bytes (which typically follows a similar approach), every neighbouring 4-bits, 2-bits and finally 1-bit pairs are masked off and swapped over with shifts. In doing so we can significantly reduce the number of operations required. Differential Revision: https://reviews.llvm.org/D21578 llvm-svn: 276432
* [Support] Make ErrorAsOutParameter take an Error* rather than an Error&.Lang Hames2016-07-223-6/+5
| | | | | | | | | | | | | | | | | | | | | | This allows ErrorAsOutParameter to work better with "optional" errors. For example, consider a function where for certain input values it is known that the function can't fail. This can now be written as: Result foo(Arg X, Error *Err) { ErrorAsOutParameter EAO(Err); if (<Error Condition>) { if (Err) *Err = <report error>; else llvm_unreachable("Unexpected failure!"); } } Rather than having to construct an ErrorAsOutParameter under every conditional where Err is known to be non-null. llvm-svn: 276430
* [RDF] Make the graph construction/use less expensiveKrzysztof Parzyszek2016-07-222-7/+23
| | | | | | | | | - FuncNode::findBlock traverses the function every time. Avoid using it, and keep a cache of block addresses in DataFlowGraph instead. - The operator[] in the map of definition stacks was very slow. Replace the map with unordered_map. llvm-svn: 276429
* [pdb] Move file layout header structs to RawTypes.hZachary Turner2016-07-223-80/+26

* [pdb] Round-trip module & file info to/from YAML.Zachary Turner2016-07-226-65/+228
| | | | | | | | | | This implements support for writing compiland and compiland source file info to a binary PDB. This is tested by adding support for dumping these fields from an existing PDB to yaml, reading them back in, and dumping them again and verifying the values are as expected. llvm-svn: 276426

* [X86][AVX] Added support for lowering to VBROADCASTF128/VBROADCASTI128 ↵Simon Pilgrim2016-07-224-12/+72
| | | | | | | | | | | | | | | | (reapplied) As reported on PR26235, we don't currently make use of the VBROADCASTF128/VBROADCASTI128 instructions (or the AVX512 equivalents) to load+splat a 128-bit vector to both lanes of a 256-bit vector. This patch enables lowering from subvector insertion/concatenation patterns and auto-upgrades the llvm.x86.avx.vbroadcastf128.pd.256 / llvm.x86.avx.vbroadcastf128.ps.256 intrinsics to match. We could possibly investigate using VBROADCASTF128/VBROADCASTI128 to load repeated constants as well (similar to how we already do for scalar broadcasts). Reapplied with fix for PR28657 - removed intrinsic definitions (clang companion patch to be be submitted shortly). Differential Revision: https://reviews.llvm.org/D22460 llvm-svn: 276416

* Don't remove side effecting instructions due to ConstantFoldInstructionDavid Majnemer2016-07-225-9/+20

* Avoid dsymutil calls to getFileNameByIndex.Pete Cooper2016-07-221-6/+11
| | | | | | | | | | | | This change adds a hasFileAtIndex method. getChildDeclContext can first call this method, and if it returns true it knows it can then lookup the resolved path cache for the given file index. If we hit that cache then we don't even have to call getFileNameByIndex. Running dsymutil against the swift executable built from github gives a 20% performance improvement without any change in the binary.

* [MIRTesting] Abort when failing to parse a function.Quentin Colombet2016-07-211-2/+4
| | | | | | | | | | When we failed to parse a function in the mir parser, we should abort the whole compilation instead of continuing in a weird state.

| | | | | | | | | | | | | | | | | | simplifications (PR28466) rL245171 exposed a hole in InstSimplify that manifested in a strange way in PR28466: https://llvm.org/bugs/show_bug.cgi?id=28466 It's possible to use trunc + icmp sgt/slt in place of an and + icmp eq/ne, so we need to recognize that pattern to eliminate selects that are choosing between some value and some bitmasked version of that value.

| | | | | | | | | | | | | | | | | | | | | Summary: The llvm.invariant.start and llvm.invariant.end intrinsics currently support specifying invariant memory objects only in the default address space. With this change, these intrinsics are overloaded for any adddress space for memory objects and we can use these llvm invariant intrinsics in non-default address spaces. Example: llvm.invariant.start.p1i8(i64 4, i8 addrspace(1)* %ptr) This overloaded intrinsic is needed for representing final or invariant memory in managed languages.
