Hi, This patch (or whatever combination of patches became r229129) caused an ICE to show up in my random testing of the AArch64 arm_neon.h intrinsics. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68134 I've tried reproducing the failure on other targets but I can't seem to get it to trigger elsewhere.
