From 18165efa8203a34d82f60a1831ea290e7304c654 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 9 Jun 2014 11:16:37 +0900 Subject: scripts: objdiff: improve path flexibility for record command Prior to this commit, scripts/objdiff expected to be run at the top directory and only the relative path of objects. This commit provides more flexibility in terms of object path: [1] scripts/objdiff can be run in any directory For example, $ scripts/objdiff record init/main.o and $ cd init; ../scripts/objdiff record main.o produce the same result. [2] Support absolute path for objects $ scripts/objdiff record /home/foo/bar/linux/init/main.o work as well.
