Altivec

[Jonas Smedegaard]

Hi,

I notice in recent changelog of VLC that apparently it is now built with 
altivec on PowerPC, as a fix for bug#660936.

Is that ok?  I mean, do we no longer support non-altivec PowerPC 
machines, or is it somehow ensured that only an Altivec plugin is 
affected, not all code?

For 32 bit x86 I believe it is ok to optimize for 486 (i.e. we no longer 
support 386) but not (generally) to optimize for 686.

In the past Altivec was similar to 686 (i.e. only optimize when also 
providing a non-optimized variant or plugin).  I am unaware if that has 
changed, or if perhaps there is some official place to lookup current 
status.
