--- Comment #2 from Filip Kastl <pheeck at gcc dot gnu.org> ---
Indeed. Current trunk successfully eliminates the call to foo.

gcc testcase.c -S -O2

main:=20
        movl    $0, a(%rip)=20=20=20=20
        xorl    %eax, %eax=20=20=20=20
        movl    $6, b(%rip)=20=20=20=20
        movl    $0, d(%rip)=20=20=20=20
        ret

Setting this as fixed.=
