I see this on aarch64-linux-gnu also.
t:
stp x29, x30, [sp, -32]!
add x29, sp, 0
movi v0.4s, 0xa
#APP
// 6 "t.c" 1
#v0
// 0 "" 2
#NO_APP
str q0, [x29, 16]
bl e
ldr q0, [x29, 16]
#APP
// 8 "t.c" 1
#v0
// 0 "" 2
#NO_APP
ldp x29, x30, [sp], 32
ret
So it is even worse for AARCH64 since it is not even a load, it is a move.
