It is seen at the highest level in GCC using the ARM NEON intrinsic:
uint16x8_t vshll_n_u8(uint8x8_t a, __constrange(0,8) int b);

It seems to work in 4.4.0. The code:
register int16x8_t a asm ("q7");
asm (
"vadd.i32 %q0, %q1, %q2 \n\t"
: "=w" (a)
: "w" (b), "w" (c)
);

Bug 37188 answers half the problem. It still does not answer why:
register int16x8_t val asm ("q0");
compiles without warning yet does not put "val" into the "q0" NEON register.
mbly nearly impossible for NEON code.
