Just a bit of a heads-up.. I have a simple patch to allow optimizing LFS
builds and am running a test now; examining the Makefile though, it
looks fine. I haven't added support to ?LFS because I'm not so
concerned with them and haven't time to test them yet, but it should be
as easy as dropping a couple function calls in place for anyone who
wants to try it.
Assuming this build completes ok, I'll clean up the patch and submit it
to you.
There are two config files:
common/opt_config: Enable/disable optimization
Select default optimization level
Define each optimization level
ie: OPTIMIZE=1
DEF_OPT_LEVEL=1
CFLAGS_0="unset"
CXXFLAGS_0=$CFLAGS_0
LDFLAGS_0="unset"
CFLAGS_1="-O3 -march=athlon-fx -pipe -s"
CXXFLAGS_1=$CFLAGS_1
LDFLAGS_1="-s"
common/def_opt_override: {$name $optLvl \n}
ie: gcc 0
binutils 0
glibc 0
Anything not defined in common/def_opt_override is optimized with the
default level, anything in common/def_opt_override is optimized with the
settings defined for the assigned level.
Pretty straight forward, and it seems to work well. I'll get back to
you in a bit.
Regards,
Jeremy.
