Modified files:
sys/boot/i386/boot2 Makefile boot2.c
Log:
Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.
Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.
Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and " " devices (I might add wd back to
keep bde happy).
o eliminate support for a few arguments.
This takes us from -162 bytes free to 67 bytes free.
I've tested this only on a few systems, so be careful when updating to
this change.
