See <http://gcc.gnu.org/bugs.html> for instructions. The simplified preprocessed source code is: ----------------------------------------------- typedef __builtin_neon_sf float32x4_t __attribute__ ((__vector_size__ (16))); typedef __builtin_neon_sf float32_t; __extension__ static __inline float32x4_t __attribute__ ((__always_inline__)) vmulq_n_f32 (float32x4_t __a, float32_t __b) { return (float32x4_t)__builtin_neon_vmul_nv4sf (__a, __b, 3); } void x(float32x4_t v0, float32_t f) { float32x4_t vv = vmulq_n_f32( v0, f); } ------------------------------------------------ The complete command line is cc1plus "-fpreprocessed" "t0d2.ii" "-quiet" "-dumpbase" "t0d.cpp" "-march=armv7-a" "-mfloat-abi=softfp" "-mfpu=neon" "-auxbase-strip" "obj/t0d.o" "-O2" "-o" "t0d.s" This ICE is also existed in GCC 4.6.
