--- Comment #6 from chrbr at gcc dot gnu.org ---
This test also ICEs for aarch64 the same way
-----------------------------------------
#include <arm_neon.h>
int8x8_t a, b;
int16x8_t e;
void
__attribute__ ((target("+simd")))
foo(void)
{
e = (int16x8_t) vaddl_s8(a, b);
}
-----------------------------------------
internal compiler error: in copy_to_mode_reg, at explow.c:595
return (int16x8_t) __builtin_aarch64_saddlv8qi (__a, __b);
called with:
cc1 -quiet pr68674.c -mcpu=cortex-a53+nosimd -O2
The reason is that DECL_MODE is been initialized to a scalar during layout_decl
since TARGET_SIMD is not set during the global initialization.
