<pre>This is what I see with current trunk:
_i1_store: ; @i1_store
.cfi_startproc
; %bb.0: ; %start
sub sp, sp, #32 ; =32
stp x29, x30, [sp, #16] ; 8-byte Folded Spill
.cfi_def_cfa_offset 32
.cfi_offset w30, -8
.cfi_offset w29, -16
add x8, sp, #8 ; =8
str x8, [sp] ; 8-byte Folded Spill
bl _foo
; implicit-def: $x8
mov w9, w0
bfxil x8, x9, #0, #32
mov w9, w1
bfi x8, x9, #32, #1
ubfx x9, x8, #0, #32
mov w0, w9
ubfx x8, x8, #32, #1
mov w1, w8
str w0, [sp, #8]
ubfx w0, w1, #0, #1 <------- zero-extend
ldr x8, [sp] ; 8-byte Folded Reload
strb w0, [x8, #4]
ldp x29, x30, [sp, #16] ; 8-byte Folded Reload
add sp, sp, #32 ; =32
ret
Since r332449 where we now split aggregates it looks like we're now doing the
right thing.</pre>
