cpu.cpp: avoided the need for wrapper functions by calling the OS-specific function directly (declared in central header, implemented in the platform's cpp file) avoid the need for init in cpu and ia32 via if(!init) Init() pattern. optimized memcpy now requires SSE support remove error-prone CAS macro; replace with cpu_CAS config: no longer require inline asm for float->int conversions lib_error: remove special-case in CHECK_ERR for windows (no longer needed) This was SVN commit r5365.
