Re: Altivec matmul kernel (attachment)


There is actually a version of gcc that recognizes altivec keywords.  It 
is available in source or rpm binary form for Linux at www.altivec.org.  
(I actually used Mac OS X for writing the code; the compiler is also a 
patched version of gcc that recognizes altivec instructions, among other 

However, I recognize that Debian users won't find that so convenient.  
I'm not sure how to go about generating assembly output, though, since 
my kernel source file isn't compiled directly but rather is used by 
Atlas to generate code...any suggestions?
