Hi,

I am building FreeBSD kernel with gcc 4.1.1. I can see the foloowing
assembler error: My assemler version is   GNU assembler 2.17


../../../../../src/bsd/sys/i386/i386/locore.s: Assembler messages:

../../../../../src/bsd/sys/i386/i386/locore.s:362: Error: suffix or
operands invalid for `mov'

../../../../../src/bsd/sys/i386/i386/locore.s:379: Error: suffix or
operands invalid for `mov'

../../../../../src/bsd/sys/i386/i386/locore.s:397: Error: suffix or
operands invalid for `mov'

*** Error code 1 (continuing)

The code in lcore.s is :

 movl    UC_GS(%eax),%gs         /* restore %gs */

 movl    UC4_GS(%eax),%gs        /* restore %gs */

 movl    SC_GS(%eax),%gs         /* restore %gs */

What is the patch for this problem? what should I use mov/movw?


The same errors for


bsd/sys/i386/i386/swtch.s

 movl    %gs,PCB_GS(%edx)
 movl    PCB_GS(%edx),%gs
 movl    %gs,PCB_GS(%ecx)

bsd/sys/i386/include/cpufunc.h

 __asm __volatile("movl %%gs,%0" : "=rm" (sel));
 __asm __volatile("mov %0,%%fs" : : "rm" (sel));
 __asm __volatile("movl %0,%%gs" : : "rm" (sel));

Thanks
Chandra
