Hi Matthias,

png_init_filter_functions_vsx() is implemented in:


Looks like the two files found in:


are not merged. If you include them, for instance:


the issue is resolved (on PPC64 at least - probably we have to adapt the build
for not breaking it on other archs?. Also I'm not sure if the optimized code
will kick in just by including the missing files).

However I could not find the Intel intrinsics [1] as well imported to OpenJDK
tree. Is that intentional? I mean, shouldn't we enable optimization when it's

Best regards,
