ARC Machine Directives
----------------------

   The ARC version of `as' supports the following additional machine
directives:

`.2byte EXPRESSIONS'
     *TODO*

`.3byte EXPRESSIONS'
     *TODO*

`.4byte EXPRESSIONS'
     *TODO*

`.extAuxRegister NAME,ADDRESS,MODE'
     *TODO*

            .extAuxRegister mulhi,0x12,w

`.extCondCode SUFFIX,VALUE'
     *TODO*

            .extCondCode is_busy,0x14

`.extCoreRegister NAME,REGNUM,MODE,SHORTCUT'
     *TODO*

            .extCoreRegister mlo,57,r,can_shortcut

`.extInstruction NAME,OPCODE,SUBOPCODE,SUFFIXCLASS,SYNTAXCLASS'
     *TODO*

            .extInstruction mul64,0x14,0x0,SUFFIX_COND,SYNTAX_3OP|OP1_MUST_BE_IMM

`.half EXPRESSIONS'
     *TODO*

`.long EXPRESSIONS'
     *TODO*

`.option ARC|ARC5|ARC6|ARC7|ARC8'
     The `.option' directive must be followed by the desired core
     version. Again `arc' is an alias for `arc6'.

     Note: the `.option' directive overrides the command line option
     `-marc'; a warning is emitted when the version is not consistent
     between the two - even for the implicit default core version
     (arc6).

`.short EXPRESSIONS'
     *TODO*

`.word EXPRESSIONS'
     *TODO*
