Most probably your compiler was not targeted to the right variant of
PowerPC CPU... There are the 'generic', 'spe' and 'altivec' variants
for PPC.
For instance the target name should be 'powerpc-eabispe' or
'powerpc-eabisimaltivec' instead of the generic 'powerpc-eabi', if
wanting to produce
any code for the 'SPE' or 'e500' variant or for one of the Altivec
types, or just wanting this code generation being the default. Older
GCCs before
gcc-4.0 could require the target name being different for getting any
code for the 'e500' type CPUs...
My guess was confirmed by the following clause from a year ago, seen on
the 'gcc' maillist :
"As another secondary issue, I consider it a bug in the PowerPC back
end that command-line options (like -misel) are silently ignored in the
default
configuration."
