The following workaround was suggested by upstream and seemed to do the

platforms/arches that don't require it.
Why would it be arch-dependent whether or not a variable needs to be
initialized?
These warnings are issued from the optimizers. There are some GCC
optimizations which are architecture-specific and run very early, before
the warnings discussed here are generated.
-Werror for optimizer-dependent warnings is usually not a good idea for
this reason.
Any specific recommendations for this issue? Should the variables be
initialized on x86_64 too or some kind of conditional implemented?
What's the definition of the float4 type?
Thanks,
Florian
