From 1cd6472e3f8d3fdee0fd19f7088807b284d3080f Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 1 Dec 2016 14:00:25 +0100 Subject: tools build: Make fixdep parsing wait for last target The fixdep tool, among other things, replaces the target of the object in the gcc generated dependency output file. The parsing code assumes there's only single target in the rule but this is not always the case as described in here: https://gcc.gnu.org/ml/gcc-help/2016-11/msg00099.html Make the fixdep code smart enough to skip all the possible targets.
