This directive expects zero or more expressions, separated by commas. If there
|
|
are no expressions then the directive does nothing. Otherwise each expression
|
|
is evaluated in turn and placed in the next two bytes of the current output
|
|
section, using the endian model of the target. If an expression will not fit
|
|
in two bytes, a warning message is displayed and the least significant two
|
|
bytes of the expression's value are used. If an expression cannot be evaluated
|
|
at assembly time then relocations will be generated in order to compute the
|
|
value at link time.
|
|
|
|
<p>This directive does not apply any alignment before or after inserting the
|
|
values. As a result of this, if relocations are generated, they may be
|
|
different from those used for inserting values with a guaranteed alignment.
|
|
|
|
<p>This directive is only available for ELF targets,
