* [AVX512] Add support for lowering PALIGNR for v64i8.Craig Topper2016-06-051-0/+5
| | | | | | Could do this for other types to, but this is what's needed to replace the instrinsic with native IR in clang. llvm-svn: 271828
* [AVX512] Fix PANDN combining for v4i32/v8i32 when VLX is enabled.Craig Topper2016-06-051-1/+2
| | | | | | v4i32/v8i32 ANDs aren't promoted to v2i64/v4i64 when VLX is enabled. llvm-svn: 271826

* [InstCombine] less 'CI' confusion; NFCSanjay Patel2016-06-051-26/+26
| | | | | | | | | Change the name of the ICmpInst to 'ICmp' and the Constant (was a ConstantInt) to 'C', so that it's hopefully clearer that 'CI' refers to CastInst in this context. While we're scrubbing, fix the documentation comment and use 'auto' with 'dyn_cast'. llvm-svn: 271817
* [SimplifyCFG] Don't kill empty cleanuppads with multiple usesDavid Majnemer2016-06-041-0/+5
| | | | | | | | | | | | | | | | | A basic block could contain: %cp = cleanuppad [] cleanupret from %cp unwind to caller This basic block is empty and is thus a candidate for removal. However, there can be other uses of %cp outside of this basic block. This is only possible in unreachable blocks. Make our transform more correct by checking that the pad has a single user before removing the BB. This fixes PR28005. llvm-svn: 271816
* [DebugInfo, PDB] Use sparse bitfields for the name mapDavid Majnemer2016-06-041-21/+12
| | | | | | | The name map might not be densely packed on disk. Using a sparse map will save memory in such situations. llvm-svn: 271811
* [InstCombine] allow vector constants for cast+icmp foldSanjay Patel2016-06-041-1/+1
| | | | | | | This is step 1 of unknown towards fixing PR28001: https://llvm.org/bugs/show_bug.cgi?id=28001 llvm-svn: 271810

* [Analysis] Enabled BITREVERSE as a vectorizable intrinsicSimon Pilgrim2016-06-041-0/+1
| | | | | | Allows XOP to vectorize BITREVERSE - other targets will follow as their costmodels improve. llvm-svn: 271803
* [X86] Add the VR128L/H and VR256L/H to the list of vector register classes ↵Craig Topper2016-06-041-1/+5

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CALL_ONCE_... macro in the legacy pass manager with the new llvm::call_once facility. Nothing changed sicne the last attempt in r271781 which I reverted in r271788. At least one of the failures I saw was spurious, and I want to make sure the other failures are real before I work around them -- they appeared to only effect ppc64le and ppc64be. Original commit message of r271781: ---- [LPM] Reinstate r271652 to replace the CALL_ONCE_... macro in the legacy pass manager with the new llvm::call_once facility. This reverts commit r271657 and re-applies r271652 with a fix to actually work with arguments. In the original version, we just ended up directly calling std::call_once via ADL because of the std::once_flag argument. The llvm::call_once never worked with arguments. Now, llvm::call_once is a variadic template that perfectly forwards everything. As a part of this it had to move to the header and we use a generic functor rather than an explict function pointer. It would be nice to use std::invoke here but we don't have it yet. That means pointer to members won't work here, but that seems a tolerable compromise. I've also tested this by forcing the fallback path, so hopefully it sticks this time. ---- Original commit message of r271652: ---- [LPM] Replace the CALL_ONCE_... macro in the legacy pass manager with the new llvm::call_once facility. This facility matches the standard APIs and when the platform supports it actually directly uses the standard provided functionality. This is both more efficient on some platforms and much more TSan friendly. The only remaining user of the cas_flag and home-rolled atomics is the fallback implementation of call_once. I have a patch that removes them entirely, but it needs a Windows patch to land first. This alone substantially cleans up the macros for the legacy pass manager, and should subsume some of the work Mehdi was doing to clear the path for TSan testing of ThinLTO, a really important step to have reliable upstream testing of ThinLTO in all forms. ---- llvm-svn: 271800
* X86: enable TLS on Windows itaniumSaleem Abdulrasool2016-06-041-0/+1
| | | | | | | Windows itanium is nearly identical to windows-msvc (MS ABI for C, itanium for C++). Enable the TLS support for the target similar to the MSVC model. llvm-svn: 271797
* [X86][AVX2] Fix v16i16 SHL lowering (PR27730)Simon Pilgrim2016-06-041-2/+2
| | | | | | | | The AVX2 v16i16 shift lowering works by unpacking to 2 x v8i32, performing the shift and then truncating the result. The unpacking is used to place the values in the upper 16-bits so that we can correctly sign-extend for SRA shifts. Unfortunately we weren't ensuring that the lower 16-bits were zero to ensure that SHL correctly shifts in zero bits. llvm-svn: 271796
* [AsmPrinter, CodeView] There are some more ways of getting wchar_tDavid Majnemer2016-06-041-3/+5
| | | | | | | | | C++ has a builtin type called wchar_t. Clang also provides a type called __wchar_t in C mode. In C mode, wchar_t can be a typedef to unsigned short. llvm-svn: 271793
* [CodeView] Fix a busted assert in TypeTableBuilder::writeClassDavid Majnemer2016-06-041-1/+1
| | | | | | It was checking for Union when it should have checked for Interface. llvm-svn: 271792

* [InstCombine][MMX] Extend SimplifyDemandedUseBits MOVMSK support to MMXSimon Pilgrim2016-06-041-3/+9
| | | | | | | | Add the MMX implementation to the SimplifyDemandedUseBits SSE/AVX MOVMSK support added in D19614 Requires a minor tweak as llvm.x86.mmx.pmovmskb takes a x86_mmx argument - so we have to be explicit about the implied v8i8 vector type. llvm-svn: 271789
* [LPM] Revert r271781 which was a re-commit of r271652.Chandler Carruth2016-06-042-1/+28
| | | | | | | | | | | | There appears to be a strange exception thrown and crash using call_once on a PPC build bot, and a *really* weird windows link error for GCMetadata.obj. Still need to investigate the cause of both problems.

* [MC] Check the upper bound in truncate assertionPetr Hosek2016-06-041-1/+1
| | | | | | | | | | The truncateToSize function already has assertion to check the lower boundary for the number bytes, but it does not check the upper boundary which could still lead to usage errors. Differential Revision: http://reviews.llvm.org/D20755 llvm-svn: 271773

* [esan|wset] Optionally assume intra-cache-line accessesDerek Bruening2016-06-031-2/+16
| | | | | | | | | | | | | | | | | | Summary: Adds an option -esan-assume-intra-cache-line which causes esan to assume that a single memory access touches just one cache line, even if it is not aligned, for better performance at a potential accuracy cost. Experiments show that the performance difference can be 2x or more, and accuracy loss is typically negligible, so we turn this on by default. This currently applies just to the working set tool.

* Re-apply "SDAG: Update ChainNodesMatched as nodes are deleted"Justin Bogner2016-06-031-4/+9
| | | | | | | | | | | | | | | My first attempt at this had an overly aggressive assert - chain nodes will only be removed, but we could hit the assert if a non-chain node was CSE'd (NodeToMatch, for instance). This reapplies r271706 by reverting r271713 and fixing an assert. Original message: Avoid relying on UB by looking into deleted nodes for a marker value. Instead, update the list of chain nodes as we go. llvm-svn: 271733

* [Symbolize] Check if the PE file has a PDB and emit an error if we can't load itReid Kleckner2016-06-032-64/+101
| | | | | | | | | | | | | | | | | | | | | Summary: Previously we would try to load PDBs for every PE executable we tried to symbolize. If that failed, we would fall back to DWARF. If there wasn't any DWARF, we'd print mostly useless symbol information using the export table. With this change, we only try to load PDBs for executables that claim to have them. If that fails, we can now print an error rather than falling back silently. This should make it a lot easier to diagnose and fix common symbolization issues, such as not having DIA or not having a PDB.

* [WebAssembly] Emit type signatures for declared functionsDerek Schuff2016-06-033-10/+56
| | | | | | | | | | | | | | | | | | | | | Under emscripten, C code can take the address of a function implemented in Javascript (which is exposed via an import in wasm). Because imports do not have linear memory address in wasm, we need to generate a thunk to be the target of the indirect call; it call the import directly. To make this possible, LLVM needs to emit the type signatures for these functions, because they may not be called directly or referred to other than where the address is taken. This uses s new .s directive (.functype) which specifies the signature. Differential Revision: http://reviews.llvm.org/D20891 Re-apply r271599 but instead of bailing with an error when a declared function has multiple returns, replace it with a pointer argument. Also add the test case I forgot to 'git add' last time around. llvm-svn: 271703
