Renato Golin	6ccf5849d2	[VPlan] Script to extract VPlan digraphs from log ... The vectoriser's debug log prints VPlan digraphs, but it's a bit cumbersome to extract them and render them into PNG images. This script does exactly that, being careful enough to extract all individual plans, name them appropriately and save in either .dot or .png files. Example usage: $ opt -O3 -debug-only=loop-vectorize file.ll -S -o /dev/null 2> debug.log $ $LLVM_SRC/utils/extract_vplan.py < debug.log Exporting VF1UF1 to DOT: VPlanVF1UF1.dot Exporting VF24UF1 to DOT: VPlanVF24UF1.dot $ $LLVM_SRC/utils/extract_vplan.py --png < debug.log Exporting VF1UF1 to PNG via dot: VPlanVF1UF1.png Exporting VF24UF1 to PNG via dot: VPlanVF24UF1.png $ xdot VPlanVF1UF1.dot Differential Revision: https://reviews.llvm.org/D53142 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@344599 91177308-0d34-0410-b5e6-96231b3b80d8	2018-10-16 09:37:52 +00:00
