--- Comment #1 from baoshan <pangbw at gmail dot com> ---
One observation is that without "-mfloat-abi=hard -mfpu=neon", I will get
this:
./xgcc y.i -B. -O2
y.i: In function âs32_to_f32_imm1â:
y.i:4:3: error: inconsistent operand constraints in an âasmâ
__asm__ ("vcvt.f32.s32 %0, %1, #1" : "=w"(y) : "0"(x));
