@subsection Options specific to PDP11 targets

@c man begin OPTIONS
|
||||
|
||||
For the pdp11-aout target, three variants of the output format can be
|
||||
produced as selected by the following options. The default variant
|
||||
for pdp11-aout is the @samp{--omagic} option, whereas for other
|
||||
targets @samp{--nmagic} is the default. The @samp{--imagic} option is
|
||||
defined only for the pdp11-aout target, while the others are described
|
||||
here as they apply to the pdp11-aout target.

||||

@item -N
|

@kindex --omagic
|
||||
@itemx --omagic
|
||||
|
||||
Mark the output as @code{OMAGIC} (0407) in the @file{a.out} header to
|
||||
indicate that the text segment is not to be write-protected and
|
||||
shared. Since the text and data sections are both readable and
|
||||
writable, the data section is allocated immediately contiguous after
|
||||
the text segment. This is the oldest format for PDP11 executable
|
||||
programs and is the default for @command{ld} on PDP11 Unix systems
|
||||
from the beginning through 2.11BSD.
|
||||
|
||||
@kindex -n
|
||||
@item -n
|
||||
@kindex --nmagic
|
||||
@itemx --nmagic
|
||||
|
||||
Mark the output as @code{NMAGIC} (0410) in the @file{a.out} header to
|
||||
indicate that when the output file is executed, the text portion will
|
||||
be read-only and shareable among all processes executing the same
|
||||
file. This involves moving the data areas up to the first possible 8K
|
||||
byte page boundary following the end of the text. This option creates
|
||||
a @emph{pure executable} format.
|
||||
|
||||
@kindex -z
|
||||
@item -z
|
||||
@kindex --imagic
|
||||
@itemx --imagic
|
||||
|
||||
Mark the output as @code{IMAGIC} (0411) in the @file{a.out} header to
|
||||
indicate that when the output file is executed, the program text and
|
||||
data areas will be loaded into separate address spaces using the split
|
||||
instruction and data space feature of the memory management unit in
|
||||
larger models of the PDP11. This doubles the address space available
|
||||
to the program. The text segment is again pure, write-protected, and
|
||||
shareable. The only difference in the output format between this
|
||||
option and the others, besides the magic number, is that both the text
|
||||
and data sections start at location 0. The @samp{-z} option selected
|
||||
this format in 2.11BSD. This option creates a @emph{separate
|
||||
executable} format.
|
||||
|
||||
@kindex --no-omagic
|
||||
@item --no-omagic
|
||||
|
||||
Equivalent to @samp{--nmagic} for pdp11-aout.
