Hello,

would it be possible for you to check whether this problem still occurs under gcc mainline? Aldy's 
done a lot of work fixing Altivec bugs, so it'd be good to know whether this was one of them. 
Thanks,

Dara

Actually I think this bug is still there because gcc is expanding many macros, a 
workaround is to use tempary variables, this will also speed up the compile.

Also send the *un*preprocessed source file.

I will double check with the new line.   I am not sure what temporary
variables you mean?  Could you enlighten me?

instead of vec_stx(vec_add(vec_ld(...),vec_ld(...)),..) do 
vector int temp = vec_ld(...);
vector int temp1 = vec_ld(...);
vector int temp2 = vec_add(temp, temp1);
vec_stx(temp,..);

We need the non preprocessed source file.
It will be called something.c.

No feed back in 3 months (T-8 days) plus this really has been in waiting for the 
unpreprocessed source file for over 6 months.
