@cindex options for PDP-11
|
|
|
|
The PDP-11 version of @code{@value{AS}} has a rich set of machine
|
|
dependent options.
|
|
|
|
@subsection Code Generation Options
|
|
|
|
@table @code

@subsection Instruction Set Extension Options
|
|
|
|
These options enables or disables the use of extensions over the base
|
|
line instruction set as introduced by the first PDP-11 CPU: the KA11.

|
Most options come in two variants: a @code{-m}@var{extension} that
|
|
enables @var{extension}, and a @code{-mno-}@var{extension} that disables
|
|
@var{extension}.
|

@code{@value{AS}} supports both DEC syntax and BSD syntax. The only

difference is that in DEC syntax, a @code{#} character is used to denote

|
an immediate constants, while in BSD syntax the character for this

|
purpose is @code{$}.

|
@cindex PDP-11 general-purpose register syntax

eneral-purpose registers are named @code{r0} through @code{r7}.

Mnemonic alternatives for @code{r6} and @code{r7} are @code{sp} and

@code{pc}, respectively.

Floating-point registers are named @code{ac0} through @code{ac3}, or
