I think this is by design, you did not change the ABI to be a non SPE based
one.

Setting -mabi=no-spe corrects the the first example.

The new prexeth.i example still generates evldd/evstdd even with -mabi=no-spe,
adding the -mno-spe flag makes no difference.

after compiling, evstdd and evldd instructions are emitted even though the
-mno-spe flag was specified.
