This is a refactoring patch that removes the redundancy of performing operand reordering twice, once in buildTree() and later in vectorizeTree(). To achieve this we need to keep track of the operands within the TreeEntry struct while building the tree, and later in vectorizeTree() we are just accessing them from the TreeEntry in the right order. This patch is the first in a series of patches that will allow for better operand reordering across chains of instructions (e.g., a chain of ADDs), as presented here: https://www.youtube.com/watch?v=gIEn34LvyNo Patch by: @vporpo (Vasileios Porpodas) Differential Revision: https://reviews.llvm.org/D59059 ........ Reverted due to buildbot failures that I don't have time to track down. llvm-svn: 355913 |
