[MPlayer-dev-eng] Fw: Re: [gentoo-ppc-dev] mplayer altivec patches

This is interesting...
Maybe configure should do a test and use a local header file
if it's possible...

this is a bad hack imo, as it just disables optimized code, what you are
trying to fix is in fact a gcc bug, "mergel" is broken.
we are already working on a fix for this.

here's a temporal fix for everyone who can't wait: 

Snip from altivec.h

#define vec_any_out(a1, a2) __builtin_altivec_vcmpbfp_p (__CR6_EQ_REV, 
(a1), (a2)
+#include <broken_mergel.h>
#endif /* __cplusplus */

add this to your altivec.h and copy the attatched header to the same
location altivec.h is in.

thx again lu_zero for finding the fix :)
