With an arm-linux-gnueabi toolchain I see the following code - it's pointless
creating space on the stack in this case.
foo:
@ args = 0, pretend = 0, frame = 8
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
add r0, r0, r0, lsr #16
sub sp, sp, #8
sxth r0, r0
add sp, sp, #8
bx lr
Possibly related to PR36409.
