From one of data sheets: In ARM state, all instructions are conditionally executed according to the state of the
CPSR condition codes and the instruction’s condition field. This field (bits 31:28)
determines the circumstances under which an instruction is to be executed. If the state
of the C, N, Z and V flags fulfils the conditions encoded by the field, the instruction is
executed, otherwise it is ignored. When condition is set the mnemonic of instruction is extended with one of suffixes like EQ, NE, CS, CC etc. |
