--- Comment #4 from Wilco <wilco at gcc dot gnu.org> ---
Clearly rematerialization isn't working correctly. Immediates and constant
addresses like this should never be spilled (using MOV/MOVK could increase
codesize, but with -Os you should use the literal pool anyway). Check
legitimate_constant_p returns true, see
https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00052.html for how it's done on
AArch64.
