From 9c4f25cc11ab1b3a4d73a4db3905ec079d9d122a Mon Sep 17 00:00:00 2001 From: Andrew Pinski Date: Wed, 11 Feb 2015 10:18:45 +0000 Subject: [PATCH] Fix bug 64893: ICE with vget_lane_u32 with C++ front-end 2015-02-11 Andrew Pinski PR target/64893 * config/aarch64/aarch64-builtins.c (aarch64_init_simd_builtins): Change the first argument type to size_type_node and add another size_type_node. (aarch64_simd_expand_builtin): Handle the new argument to AARCH64_SIMD_BUILTIN_LANE_CHECK and don't ICE but rather print an out when the first two arguments are not nonzero integer constants. * config/aarch64/arm_neon.h (__AARCH64_LANE_CHECK): Pass the sizeof directly to __builtin_aarch64_im_lane_boundsi. 2015-02-11 Andrew Pinski PR target/64893 * c-c++-common/torture/aarch64-vect-lane-1.c: New testcase. * c-c++-common/torture/aarch64-vect-lane-2.c: New testcase.
