Hi

***********************************

unsigned long long foo=0;
int main (void)
{
  foo=0;
  return 0;
}

***********************************

valy@desktop:~/dev/C/test4$ gcc -Wall -save-temps -march=opteron  -masm=intel
test1.c -o intel_asm_sample
test1.s: Assembler messages:
test1.s:19: Error: invalid operand for 'mov' ('(' unexpected)

Modèle de thread: posix
version gcc 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

***********************************

Everything is OK without "-masm=intel"
Everything is OK with variable "foo" inside main()
Everything is worse when variable "foo" > 0x7fffffff: we have the same error
twice.

This gcc was released with xubuntu 7.10, I may try a newer gcc version.

Regards
