# Support for tracing what gbuild does.

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