$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_SETR3TOR31_POP_R31 r3=r31. Load LR from stackreg+20, load r31 from stackreg+12, add stackreg with 16 then jump to LR.
