clang-p2996/llvm/test/Transforms/SLPVectorizer/slp-max-phi-size.ll
Alexey Bataev d65cc85977 [SLP]Do not schedule instructions with constants/argument/phi operands and external users. 
No need to schedule entry nodes where all instructions are not memory
read/write instructions and their operands are either constants, or
arguments, or phis, or instructions from others blocks, or their users
are phis or from the other blocks.
The resulting vector instructions can be placed at
the beginning of the basic block without scheduling (if operands does
not need to be scheduled) or at the end of the block (if users are
outside of the block).
It may save some compile time and scheduling resources.
