Package: libdirectfb-0.9-24
Version: 0.9.24-3
Severity: important
The libdirectfb uses the assembly instructions to implement the rdtsc
function on the X86 platform (file memcpy.c from line 520):
#ifdef ARCH_X86
static inline unsigned long long int rdtsc()
{
unsigned long long int x;
__asm__ volatile (".byte 0x0f, 0x31" : "=A" (x));
return x;
}
#else
static inline unsigned long long int rdtsc()
{
struct timeval tv;
gettimeofday (&tv, NULL);
return (tv.tv_sec * 1000000 + tv.tv_usec);
}
#endif
This construct causes libdirectfb to generate SIGILL when running on
x86 machine without rdtsc (eg. AMD x586)
