--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Was this maybe fixed by

2015-10-13  Richard Sandiford  <richard.sandiford@arm.com>

        * real.h (real_isinteger): Declare.
        * real.c (real_isinteger): New function.
        * match.pd: Simplify pow(|x|,y) and pow(-x,y) to pow(x,y)
        if y is an even integer.
