macromedia plug-ins

[Greg Hamilton]

Yes and no. There's only one Flash plugin for OS X. It works on any PPC 
Mac that can run OS X. YDL provide a single binary distribution of 
GNU/Linux which will install on just about any PPC hardware, Mac or 
otherwise.

If a binary doesn't require AltiVec support it should run on any PPC 
Mac running Linux.

I suppose a 64-bit version would be required for a G5 running the new 
64-bit version of YDL.

Anyway, this got me wondering about how G3s cope with code compiled to 
use the AltiVec. Are there library functions to emulate the AltiVec 
instructions for processors which don't have an AltiVec? Apparently 
not. I compiled an AltiVec sample program. It runs on a G4. It outputs 
'Illegal instruction' and terminates on a G3. I guess it's up to the 
programmer to test for AltiVec and avoid AltiVec specific functions on 
PPC <= G3.
