Subject: Two requested changes to tick processor.
X-Git-Tag: upstream/4.7.83~23859
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1e18e55c15350d1af880be6e631aa6f200619b38;p=platform%2Fupstream%2Fv8.git

Two requested changes to tick processor.

1. If D8_PATH isn't specified, first try to locate 'd8' shell in path,
   and if not found, fallback to the one in tools_path/..
2. Add '--nm=<nm_exec>' parameter to specify 'nm' executable to use.
