Sparc Machine Directives
------------------------

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

`.common'
     This must be followed by a symbol name, a positive number, and
     `"bss"'.  This behaves somewhat like `.comm', but the syntax is
     different.

`.half'
     This is functionally identical to `.short'.

`.proc'
     This directive is ignored.  Any text following it on the same line
     is also ignored.

`.reserve'
     This must be followed by a symbol name, a positive number, and
     `"bss"'.  This behaves somewhat like `.lcomm', but the syntax is
     different.

`.seg'
     This must be followed by `"text"', `"data"', or `"data1"'.  It
     behaves like `.text', `.data', or `.data 1'.

`.skip'
     This is functionally identical to the `.space' directive.

`.word'
     On the Sparc, the .word directive produces 32 bit values, instead
     of the 16 bit values it produces on many other machines.
