No reason, probably finger memory without lots of thinking.
The reason for -mno-mmx is that the functions use floating point vectors
and scalar floating point arithmetics in the same function.
Feel free to change both pr63594-{1,2}.c with s/linux//g .

Works fine on x86_64, and doesn't seem to be related to the fix in any way,
it seems the ICE is related to returning or passing the vectors, so
supposedly some latent Solaris/SPARC issue?
