That asm part can safely be replaced by
Code:
const BYTE* src2 = src - 8 * srcpitch - 1;
unsigned int tmp = 0;
for (int i = 0; i < 24; i++) {
tmp |= *(unsigned int*)(src2);
src2 += srcpitch;
}
tmp &= 0x00ffffff;
Checked, compiler generates the same or better asm code for that part. No need for special 64 bit tmp, 32 bit is enough.
