> How do you do this with "make -f client.mk profiledbuild"?
To answer my own question:
Just edit ./configure and ./js/src/configure and add
"-flto=4 -fwhole-program" (or whatever you may prefer)
to the PROFILE_USE_CFLAGS variable.
Then you can build Firefox with "make -f client.mk profiledbuild".
BTW libmozsqlite3.so still gets miscompiled, but Firefox is
now snappy as never before ;-)
