[x264-devel] patch for: alignment problem on sparc (maybe others 32bit archs, too)

[Chris Fensch]

Hello,

    there is a pointer alignment problem in bs.h. s->p is no longer 
guaranteed to be aligned to word bounderies. This causes a problem on 
architectures that only support aligned word memory access, such as sparc 
(I assume a few others might also have the same problem). In such a case 
it is necessary to perform the word access as a sequence of bytes 
accesses. I attached a patch that fixes this problem for sparc, but it 
should be straight forward to modify the patch such that it also supports 
other architectures. A final note, the patch only fixes alignment problems 
on 32bit architectures. I made no effort to make it also support 64bit 
architectures that have similar alignment constraints.

Cheers
   Chris
