Some of you might remember that I posted that I was having problems
building process.c in arch/i386/kernel with the above tools. I've had the
opportunity to investigate further and here's my output:
gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2
-fomit-frame-pointer -pipe -fno-strength-reduce -m486 -DCPU=486 -S
process.c -o process.S
At this point, egcs seems to assemble it out to a .S file correctly. Now
if I either use gcc or as to generate the object file:
as process.S -o process.o
It comes back with
process.S: Assembler messages:
process.S:632: Error: operands given don't match any known 386 instruction
On going to view the process.S file, here's the snippet:
movl 20(%esp),%ecx)
#APP
movw 24(%esp),0(%ecx) <-- line 632
movw %ax,2(%ecx)
rorl $16,%eax
movb %al,4(%cx)
The corresponding part in process.c is copy_segments(). Any ideas what it
is doing wrong here?
Cheers,
Alex
