Arnold Schwaighofer b26fb77d9b Add an option to the LTO code generator to disable vectorization during LTO ... We used to always vectorize (slp and loop vectorize) in the LTO pass pipeline. r220345 changed it so that we used the PassManager's fields 'LoopVectorize' and 'SLPVectorize' out of the desire to be able to disable vectorization using the cl::opt flags 'vectorize-loops'/'slp-vectorize' which the before mentioned fields default to. Unfortunately, this turns off vectorization because those fields default to false. This commit adds flags to the LTO library to disable lto vectorization which reconciles the desire to optionally disable vectorization during LTO and the desired behavior of defaulting to enabled vectorization. We really want tools to set PassManager flags directly to enable/disable vectorization and not go the route via cl::opt flags *in* PassManagerBuilder.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220652 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-26 21:50:58 +00:00
