NettetARM programs use three methods to work around this, all of which Native Client exploits: Many instructions can encode a modified immediate, which is an 8-bit number rotated right by an even number of bits. The movw and movt instructions can be used to set the top and bottom 16-bits of a register, and can therefore encode any 32-bit immediate. Nettetmovwcopies the first operand to the second operand, including data from a descriptor. The descriptor table entry for the selector contains the data for the register. The DS and ES …
