I think you want to use rs->x[13] here. The comment in fill_regs32 in sys/arm64/arm64/machdep.c is useful: /* For arm32, SP is r13 and LR is r14 */

You probably also want to set r_lr to rs->x14.

Address andrew's feedback. Thanks!

my usual pedantic comment, keep these sorts of additions in alpha order :)
