Hi, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63673 observes that vec_vsx_ld doesn't currently permit the base pointer to have a type of pointer to double, even though this is specified as legal in the GCC user's manual. We do allow a pointer to float, so this is just an oversight. This patch corrects the problem both for vec_vsx_ld and vec_vsx_st.
Bootstrapped and tested on powerpc64-unknown-linux-gnu with no regressions. Ok for trunk, 4.9, and 4.8? Thanks, Bill 2014-11-20 Bill Schmidt <[email protected]> * config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Allow the base pointer of vec_vsx_ld and vec_vsx_st to take a pointer to double.
