C:\Temp/cceyaaaa.s: Assembler messages:
C:\Temp/cceyaaaa.s:59: Error: no such instruction: `xaddl ebx,DWORD PTR [eax-4]'

n: `addl eax,DWORD PTR [ecx]'
>How-To-Repeat:
a.cpp:
#include <string>

int main(int argc, char *argv[])
{
  std::string a="a";
}

Command line:
gcc -O3 a.cpp -lstdc++ -masm=intel
>Fix:
Use different versions of atomicity.h for intel and AT&T syntax. It will probably need to make the compiler issue a #define when -masm=intel is used.
