ARM Instructions
This appendix summarizes ARMv4 instructions used in this book. Condition encodings are given in Table 6.3.
B.1 Data-processing Instructions
Standard data-processing instructions use the encoding in Figure B.1. The 4-bit cmd field specifies the type of instruction as given in Table B.1. When the S-bit is 1, the status register is updated with the condition flags produced by the instruction. The I-bit and bits 4 and 7 specify one of three encodings for the second source operand, Src2, as described in Section 6.4.2. The cond field specifies which condition codes to check, as given in Section 6.3.2 ...
