Please note that the above includes my personal path... needs updated!
Also, it looks with -O3 I'm on around 36-40% CPU utilization. Depending on the actual platform might be useful to edit file alac.c and rewriting function 'count_leading_zeros()'. Once example my be:
static int count_leading_zeros(int input)
{
int output;
//asm("clz %0, %1" : "=r" (output) : "r" (input));
__asm
{
mov r9, input
clz r8, r9
mov output, r8
}
return output;
}
Hope this help!
I would really like to see someone to rewrite the whole perl script in a compilable language! This would save a lot of space!
Thanks,
Gregory Dymarek
