Hi,
While working on shared compilation cache for windows, I noticed I could
get a 20% build time improvement with the following in .mozconfig:
mk_add_options "export COMPILE_PDB_FLAG="
mk_add_options "export HOST_PDB_FLAG="
mk_add_options "export MOZ_DEBUG_FLAGS=-Z7"
(the downside is a 40% disk space increase of the objdir)
This is what is currently used on try, and as far as testing goes, it is
good enough for breakpad symbols to have the right data so that crashes
in tests can be handled correctly.
I'm looking for people to test this setup more thoroughly and see if it
affects their debugging. If that works out well, we may make it the
default.
Cheers,
Mike
PS: please report what build time difference that makes for you, too.
