From d178770d8d21489abf5bafefcbb6d5243b482e9a Mon Sep 17 00:00:00 2001 From: Pi-Hsun Shih Date: Thu, 23 Jul 2020 21:15:43 -0700 Subject: scripts/decode_stacktrace: strip basepath from all paths Currently the basepath is removed only from the beginning of the string. When the symbol is inlined and there's multiple line outputs of addr2line, only the first line would have basepath removed. Change to remove the basepath prefix from all lines.
