hello
Hi Chris,
i would like to ask if it possible to change the optimization of the
kernel from -O2 to -O3 :D, how can i do that? if i change it to the top
level Makefile does it change to all the Makefiles?
search for the line with
CFLAGS += -O2
and change this to -O3.
This works for most Makefile's except for the one's that manually
set -Os.
And let's say that i change it... does this generate any problems with
the space that the kernel will take? (the kernel will be much larger)
It's completely untested.
And since it's larger, it's also slower.
Thanks
Chris
cu
Adrian
so if i want to play with and see what happens i have to change it
manually in each make file... good i may create a kernel like that to
see what will happens (just for test) ;)
thanks
Chris
