2017-05-29[Docs] Add VectorizationPlan to docs/Proposals.Ayal Zaks
Following the request made in https://reviews.llvm.org/D32871, the general documentation of the Vectorization Plan is hereby placed under docs/Proposals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@304161 91177308-0d34-0410-b5e6-96231b3b80d8
2017-05-23[LV] Report multiple reasons for not vectorizing under allowExtraAnalysisAyal Zaks
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.

2012-12-20docs: Clean up adornments.Sean Silva
For whatever reason the usage of '^^^' and '---' adornments were reversed compared to the "canonical" style of the LLVM docs (which is currently "the style used in SphinxQuickstartTemplate.rst"). This change doesn't affect the document structure at all, I'm just doing it for trivial stylistic consistency (the document content is *much* more important---thanks Nadav for writing this up!). Also, trim the adornments to be the same length as the section names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170638 91177308-0d34-0410-b5e6-96231b3b80d8
