* Rename llvm-pdbdump -> llvm-pdbutil.Zachary Turner2017-06-091-0/+4
| | | | | | | | | | This is to reflect the evolving nature of the tool as being useful for more than just dumping PDBs, as it can do many other things. Differential Revision: https://reviews.llvm.org/D34062 llvm-svn: 305106

* [docs] Make it clear shifts yield poison when shift amount >= bitwidthNuno Lopes2017-06-061-18/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some InstCombine optimizations already rely on the result being poison rather than undef. For example, the following rewrite is wrong if undef is used: ; (1 << Y) * X -> X << Y %Op0 = shl 1, %Y %r = mul %Op0, %Op1 => %r = shl %Op1, %Y ERROR: Mismatch in values for i4 %r Example: i4 %Y = 0x8 (8, -8) i4 %Op0 = 0x0 (0) i4 %Op1 = 0x0 (0) source: 0x0 (0) target: 0x1 (1) The optimization is correct if poison is returned instead: http://rise4fun.com/Alive/ygX Differential Revision: https://reviews.llvm.org/D33654 llvm-svn: 304780

* Update the documentation and CMake file for Visual Studio generators.Aaron Ballman2017-05-251-0/+4
| | | | | | By default, CMake uses a 32-bit toolchain, even when on a 64-bit platform targeting a 64-bit build. However, due to the size of the binaries involved, this can cause linker instabilities (such as the linker running out of memory). Guide people to the correct solution to get CMake to use the native toolchain. llvm-svn: 303912

* [LV] Report multiple reasons for not vectorizing under allowExtraAnalysisAyal Zaks2017-05-231-1/+3
| | | | | | | | | | | | | | | | | | | | The default behavior of -Rpass-analysis=loop-vectorizer is to report only the first reason encountered for not vectorizing, if one is found, at which time the vectorizer aborts its handling of the loop. This patch allows multiple reasons for not vectorizing to be identified and reported, at the potential expense of additional compile-time, under allowExtraAnalysis which can currently be turned on by Clang's -fsave-optimization-record and opt's -pass-remarks-missed. Removed from LoopVectorizationLegality::canVectorize() the redundant checking and reporting if we CantComputeNumberOfIterations, as LAI::canAnalyzeLoop() also does that. This redundancy is caught by a lit test once multiple reasons are reported. Patch initially developed by Dror Barak. Differential Revision: https://reviews.llvm.org/D33396 llvm-svn: 303613

* [IR] Allow attributes with global variablesJaved Absar2017-05-111-2/+11
| | | | | | | | | | | | | This patch extends llvm-ir to allow attributes to be set on global variables. An RFC was sent out earlier by my colleague James Molloy: http://lists.llvm.org/pipermail/cfe-dev/2017-March/053100.html A key part of that proposal was to extend LLVM-IR to carry attributes on global variables. This generic feature could be useful for multiple purposes. In our present context, it would be useful to carry user specified sections for bss/rodata/data.

* Introduce experimental generic intrinsics for horizontal vector reductions.Amara Emerson2017-05-091-0/+332
| | | | | | | | | | | | | | - This change allows targets to opt-in to using them instead of the log2 shufflevector algorithm. - The SLP and Loop vectorizers have the common code to do shuffle reductions factored out into LoopUtils, and now have a unified interface for generating reductions regardless of the preference of the target. LoopUtils now uses TTI to determine what kind of reductions the target wants to handle. - For CodeGen, basic legalization support is added.

* MIParser/MIRPrinter: Compute block successors if not explicitely specifiedMatthias Braun2017-05-051-0/+2
| | | | | | | | | | | | | | | | | - MIParser: If the successor list is not specified successors will be added based on basic block operands in the block and possible fallthrough. - MIRPrinter: Adds a new `simplify-mir` option, with that option set: Skip printing of block successor lists in cases where the parser is guaranteed to reconstruct it. This means we still print the list if some successor cannot be determined (happens for example for jump tables), if the successor order changes or branch probabilities being unequal.

| | | | | | | | | | | | Fixes PR31789 - When loop-vectorize tries to use these intrinsics for a non-default address space pointer we fail with a "Calling a function with a bad singature!" assertion. This patch solves this by adding the 'vector of pointers' argument as an overloaded type which will determine the address space.

* [StackMaps] Increase the size of the "location size" fieldSanjoy Das2017-04-281-2/+5
| | | | | | | | | | | | | | | | | | | | Summary: In some cases LLVM (especially the SLP vectorizer) will create vectors that are 256 bytes (or larger). Given that this is intentional[0] is likely to get more common, this patch updates the StackMap binary format to deal with the spill locations for said vectors. This change also bumps the stack map version from 2 to 3.
