From d7a3d85e08477a979933a2bb3b525a8de99543c2 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 29 May 2015 17:42:58 +0200 Subject: perf build: Do not fail on missing Build file Allow nesting into directories without Build file. Currently we force include of the Build file, which fails the build when the Build file is missing. We already support empty *-in.o' objects if there's nothing in the directory to be compiled, so we can just use it for missing Build file cases. Also adding this case under tests.
