this is what we have currently:

clang -Os  -fno-guess-branch-probability  -fomit-frame-pointer  -mno-align-long-strings  -mrtd  -mno-mmx
-mno-3dnow -mno-sse -mno-sse2 -mno-sse3  -DUFS1_AND_UFS2  -DFLAGS=0x80  -DSIOPRT=0x3f8  -DSIOFMT=0x3
-DSIOSPD=9600  -I/usr/src/sys/boot/i386/boot2/../../common  -I/usr/src/sys/boot/i386/boot2/../btx/lib -I.  -Wall
-Waggregate-return -Wbad-function-cast -Wcast-align  -Wmissing-declarations -Wmissing-prototypes -Wnested-externs
-Wpointer-arith -Wshadow -Wstrict-prototypes -Wwrite-strings  -Winline --param max-inline-insns-single=100 -mllvm
-inline-threshold=1000 -ffreestanding -mllvm -inline-threshold=1000 -mno-mmx -mno-3dnow -mno-sse -mno-sse2
-mno-sse3 -m32 -march=i386  -S -o boot2.s.tmp /usr/src/sys/boot/i386/boot2/boot2.c

ie. -Os is already there. I wonder why  the -inline-threshold has no effect.

can I disable inlining completely somehow?
