From 0bdf181fe0e5b6f6d5764ff482d7ae4707f8986b Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Thu, 7 Nov 2019 15:47:13 +0800 Subject: [PATCH] perf diff: Don't use hack to skip column length calculation Previously we use a nasty hack to skip the hists__calc_col_len for block since this function is not very suitable for block column length calculation. This patch removes the hack code and add a check at the entry of hists__calc_col_len to skip for block case.
