From 8068d34cfe4f74784cba29e981e2d8437ff02a9f Mon Sep 17 00:00:00 2001 From: k0kubun Date: Tue, 10 Jul 2018 13:05:29 +0000 Subject: Revert "benchmark/*.yml: convert from benchmark/bm_*.rb" This reverts r63900. Having single-execution benchmark as a normal Ruby script is preferred by ko1. I'm not a big fan of having inconsistent benchmark formats, but I can understand some benefits of it. common.mk: remove obsolsted benchmark-each PHONY declaration, support running Ruby scripts added by this commit.
