--- Comment #14 from Jim Wilson <wilson at gcc dot gnu.org> --- I debugged one of my gcc.c-torture/execute/builtins failures, and found a bug in the gdb aarch64 simulator with the FP stur instruction support. I submitted a patch to gdb-patches. With that fix, all of the tests in this dir are passing for me now. Hence, I am still unable to reproduce this failure with my build tree. https://sourceware.org/ml/gdb-patches/2016-12/msg00018.html
