From 5d618324dd4442d20dbdb039176787199ba2f12b Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Wed, 17 Jun 2015 14:46:29 +0000 Subject: perf tools: Move libtraceevent dynamic list to separated LDFLAGS variable Commit e3d09ec8126fe2c9a3ade661e2126e215ca27a80 ("tools lib traceevent: Export dynamic symbols used by traceevent plugins") adds libtraceevent dynamic list directly into LDFLAGS, which makes all targets depend on that list through LDFLAGS. This is not good since some of targets like libgtk.so doesn't use plugin at all, but require the existance of that list because of linker options. This patch isolates the -Xlink option into LIBTRACEEVENT_DYNAMIC_LIST_LDFLAGS, makes only perf and perf.so use it.
