------- Comment #4 from burnus at gcc dot gnu dot org 2007-06-25 19:52 ------- "At the moment the vectorizer only vectorizes builtin_pow if the exponent is either 2 or 0.5. whereas if we expand constant exponents in the gfortran frontend (gfc_conv_cst_int_power) it vectorizes for other constant integer powers as well"
I've filled PR middle-end/32503 for this. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32239
