@section M88K Machine Directives
|
||||
|
||||
The M88K version of the assembler supports the following machine
|
||||
directives:
|
||||
|
||||
@table @code
|
||||
@cindex @code{align} directive, M88K
|
||||
@item .align
|
||||
This directive aligns the section program counter on the next 4-byte
|
||||
boundary.
|
||||
|
||||
@cindex @code{dfloat} directive, M88K
|
||||
@item .dfloat @var{expr}
|
||||
This assembles a double precision (64-bit) floating point constant.
|
||||
|
||||
@cindex @code{ffloat} directive, M88K
|
||||
@item .ffloat @var{expr}
|
||||
This assembles a single precision (32-bit) floating point constant.
|
||||
|
||||
@cindex @code{half} directive, M88K
|
||||
@item .half @var{expr}
|
||||
This directive assembles a half-word (16-bit) constant.
|
||||
|
||||
@cindex @code{word} directive, M88K
|
||||
@item .word @var{expr}
|
||||
This assembles a word (32-bit) constant.
|
||||
|
||||
@cindex @code{string} directive, M88K
|
||||
@item .string "@var{str}"
|
||||
This directive behaves like the standard @code{.ascii} directive for
|
||||
copying @var{str} into the object file. The string is not terminated
|
||||
with a null byte.
|
||||
|
||||
@cindex @code{set} directive, M88K
|
||||
@item .set @var{symbol}, @var{value}
|
||||
This directive creates a symbol named @var{symbol} which is an alias for
|
||||
another symbol (possibly not yet defined). This should not be confused
|
||||
with the mnemonic @code{set}, which is a legitimate M88K instruction.
|
||||
|
||||
@cindex @code{def} directive, M88K
|
||||
@item .def @var{symbol}, @var{value}
|
||||
This directive is synonymous with @code{.set} and is presumably provided
|
||||
for compatibility with other M88K assemblers.
|
||||
|
||||
@cindex @code{bss} directive, M88K
|
||||
@item .bss @var{symbol}, @var{length}, @var{align}
|
||||
Reserve @var{length} bytes in the bss section for a local @var{symbol},
|
||||
aligned to the power of two specified by @var{align}. @var{length} and
|
||||
@var{align} must be positive absolute expressions. This directive
|
||||
differs from @samp{.lcomm} only in that it permits you to specify
|
||||
an alignment. @xref{Lcomm,,@code{.lcomm}}.
