Bug 661385

I have been using Fedora 13 for months with no issues on this topic, but since Fedora 14 I experience a weird bug consisting in that sound is played distorted on Flash (latest stable 10.1.102.65 version and even 10.2 beta) when full screen is active.

There is a similar report on bug 638477, but I'm on 32bits and the sound distortion only happens in Flash full screen mode.

I have commented the bug in https://bugzilla.redhat.com/show_bug.cgi?id=638477#c142, but I got no reply.

I wanted to check whether their fix at https://bugzilla.redhat.com/show_bug.cgi?id=638477#c55 will fix the issue I'm experiencing.

I'm afraid that my system is not able to compile:

#include <sys/types.h>

void *memcpy(void *dst, const void *src, size_t size)
{
void *orig = dst;
asm volatile("rep ; movsq"
:"=D" (dst), "=S" (src)
:"0" (dst), "1" (src), "c" (size >> 3)
:"memory");
asm volatile("rep ; movsb"
:"=D" (dst), "=S" (src)
:"0" (dst), "1" (src), "c" (size & 7)
:"memory");
return orig;
}

I get the following error:

$ gcc -O2 -c linusmemcpy.c
linusmemcpy.c: Assembler messages:
linusmemcpy.c:6: Error: number of operands mismatch for `movs'

It might be the most basic issue, but I cannot code, so it's Greek to me.

What am I missing here?

Thanks for your help,


Pablo
