locore.s: suffix or operands invalid for mov

[Unga]

Hi all

I get an error when compiling the RELENG_7 kernel on i386.

cc -c -x assembler-with-cpp -DLOCORE -O -pipe  -std=c99 -g -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual  -Wundef -Wno-pointer-sign -fformat-extensions -nostdinc  -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000  -mno-align-long-strings -mpreferred-stack-boundary=2  -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -ffreestanding -Werror /usr/src/sys/i386/i386/locore.s

/usr/src/sys/i386/i386/locore.s:358: Error: suffix or operands invalid for `mov'
*** Error code 1

Btw, I'm using a gcc 4.2.1 patched by myself. This error doesn't happen using the gcc ship with FreeBSD.

What could be the cause of this error? 

Appreciate your reply in this regard.

Kind regards
