M88K Machine Directives
-----------------------

   The M88K version of the assembler supports the following machine
directives:

`.align'
     This directive aligns the section program counter on the next
     4-byte boundary.

`.dfloat EXPR'
     This assembles a double precision (64-bit) floating point constant.

`.ffloat EXPR'
     This assembles a single precision (32-bit) floating point constant.

`.half EXPR'
     This directive assembles a half-word (16-bit) constant.

`.word EXPR'
     This assembles a word (32-bit) constant.

`.string "STR"'
     This directive behaves like the standard `.ascii' directive for
     copying STR into the object file.  The string is not terminated
     with a null byte.

`.set SYMBOL, VALUE'
     This directive creates a symbol named SYMBOL which is an alias for
     another symbol (possibly not yet defined).  This should not be
     confused with the mnemonic `set', which is a legitimate M88K
     instruction.

`.def SYMBOL, VALUE'
     This directive is synonymous with `.set' and is presumably provided
     for compatibility with other M88K assemblers.

`.bss SYMBOL, LENGTH, ALIGN'
     Reserve LENGTH bytes in the bss section for a local SYMBOL,
     aligned to the power of two specified by ALIGN.  LENGTH and ALIGN
     must be positive absolute expressions.  This directive differs
     from `.lcomm' only in that it permits you to specify an alignment.
     Note: `.lcomm'.
