freebsd stable - Apr 2003 - compiling kernel without -O

Hello!

Is it possible to compile kernel without '-O' option?
When my COPTFLAGS=-O -pipe, it compiles fine.  When I change 
COPTFLAGS=-pipe, it breaks:

cc -c -pipe  -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes  -Wmis
sing-prototypes -Wpointer-arith -Winline -Wcast-qual  -fformat-extensions -ansi
-g -nostdinc -I- -I. -I../.. -I../../../include -I../../contrib/ipfilter  -D_KER
NEL -include opt_global.h  -mpreferred-stack-boundary=2 -fomit-frame-pointer ../
../i386/i386/atomic.c
In file included from ../../i386/i386/atomic.c:47:
machine/atomic.h: In function `atomic_set_char':
machine/atomic.h:106: inconsistent operand constraints in an `asm'
machine/atomic.h: In function `atomic_clear_char':
machine/atomic.h:107: inconsistent operand constraints in an `asm'
machine/atomic.h: In function `atomic_add_char':
machine/atomic.h:108: inconsistent operand constraints in an `asm'
<snip>


Is it OK?

Thanks!

As far as I know, compiling kernel without -O is not supporterd due to
incompatibilities with assembler-optimized kernel routinges.

Correct.
