--- Comment #14 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The three testcases Richard put in comment #0 and comment #1 produce in
(released) GCC 6+:
foo(unsigned short __vector(8), unsigned short __vector(8)):
punpcklqdq %xmm1, %xmm0
ret
bar(int __vector(4), int __vector(4)):
shufps $68, %xmm1, %xmm0
ret
baz(unsigned short __vector(8), unsigned short __vector(8)):
shufpd $2, %xmm1, %xmm0
ret
So I think this is all fixed.
AARCH64 in GCC 11+ produce which was fixed by r11-2191 and r11-2192:
foo(unsigned short __vector(8), unsigned short __vector(8)):
zip1 v0.2d, v0.2d, v1.2d
ret
bar(int __vector(4), int __vector(4)):
zip1 v0.2d, v0.2d, v1.2d
ret
baz(unsigned short __vector(8), unsigned short __vector(8)):
ins v0.d[1], v1.d[1]
ret
