+hideallsymbols
This option is used to prevent all the symbols from being exported unless explicitly
exported with the +e.
+ild Specify incremental linking.
If the output file does not exist, or if it was created without the
+ild option, the
linker performs an initial incremental link. The output file produced is suitable for
subsequent incremental links. The incremental link option is valid for both executable
and shared library links.
NOTE: The HP WDB symbolic debugger only supports debugging of incrementally
linked load modules that you create with the
+objdebug compiler option enabled.
(The HP DDE debugger does not support the
+ild option.)
To debug incrementally linked binaries, they should be compiled and linked with both
+ild and +objdbg.
If you specify one of the following incompatible
ld option with +ild, the linker emits
a warning message and ignores the
+ild
option.
• The
-r option: create a relocatable object file.
• Strip options: -s and -x strip the output file. (The incremental linking requires
the parts of the output load module which are stripped out with these options.)
• Optimization options: -I, -O, -P, -PD, -PF, +df file,
+fb, +fbu, +fbs, +pgm
name, and +Oprocelim.
The following options are compatible with the +ild option with limitations:
• -D offset, -R offset
Set the origin for the data and text segments. If you change the offset after the ini-
tial incremental link, the linker performs an initial incremental link automatically.
• -k mapfile
provide a non-default mapfile. The user specified mapfile specifications are permit-
ted with the +ild option. But you should not modify the mapfile after the initial
incremental link. If the mapfile is modified after the initial link, an initial incre-
mental link is performed automatically.
+ildnowarn Suppress incremental-linking related warnings. By default, the linker issues all
incremental-linking related warnings. This option is ignored if used without
+ild or
+ildrelink .
+ildpad percentage
Control the amount of padding percentage the incremental linker allocates, relative to
sizes of object file structures being padded. By default the linker allocates 25% of pad-
ding space. This option is ignored if used without +ild or +ildrelink .
+ildrelink Perform an initial incremental link, regardless of the output load module.
In certain situations (for example, internal padding space is exhausted) the incremen-
tal linker is forced to perform an initial incremental link. The +ildrelink option
allows you to avoid such unexpected initial incremental links by periodically rebuild-
ing the output file.
+interposer
Used only when building a shared library. This creates a shared library that can be
used for interposition. When resolving references for an application with direct bind-
ing information (see -B direct), the dynamic loader searches interposer libraries
first. If the symbol cannot be resolved to any interposing libraries, the direct binding
information is used.
+[no]lazyload
Enable [disable] lazy loading of shared libraries. Loading of shared libraries specified
as +lazyload is deferred until a reference is made to it during execution.
Dependent libraries of +lazyload shared libraries will not be processed during link
time, unless they are explicitly specified on the link line.
