10 # Support for tracing what gbuild does.
11 # Run 'make GBUILD_TRACE=/somewhere/log.json', process the file
12 # using solenv/bin/finish-gbuild-trace.py, and then view it in Chromium
13 # using the chrome://tracing URL:
14 # - the '?' icon in the top-right is the help
15 # - 'gbuild' rows represent per-parallelism (per-CPU) usage in time
16 # - 'totals' rows represent sums for reach build type
17 # - note that 'EXTERNAL' targets do not detect whether the external package
18 # is built with parallelism or not, so the actual CPU time may be higher
19 # - vertical lines represent targets that themselves do not take any time
21 # - any target can be found using the search field in the top right corner
22 # (just type e.g. '[MOD]: sal' and hit the '->' button, if you cannot see
23 # it pressing 'm' or 'f' can help)
