Data processing instructions in arm

WebAlmost all ARM data processing instructions can optionally update the condition code flags according to the result. To make an instruction update the flags, include the S suffix as shown in the syntax description for the instruction.. Some instructions (CMP, CMN, TST and TEQ) do not require the S suffix.Their only function is to update the flags.
