-Fz Disable the linker feature that translates some calls to
$$dyncall_external
to
calls to
$$dyncall.
-N Generate an executable output file with file type
EXEC_MAGIC. This option is
incompatible with
-n and -q. This option causes the data to be placed immedi-
ately following the text, and makes the text writable. Files of this type cannot be
shared.
-S Generate an Initial Program Loader (IPL) auxiliary header for the output file,
instead of the default HP-UX auxiliary header.
+cdp oldpath:newpath
Replace the recorded path for a shared library in the
a.out. In 32-bit mode, ld
records the absolute path names of any shared libraries searched at link time in the
a.out file. When the program begins execution, the dynamic loader attaches any
shared libraries that were searched at link time. Although you can use the
+b
and/or +s
linker options to direct the dynamic loader to directories to search for
the shared libraries, the dynamic loader, as a last resort, searches for the shared
libraries in its absolute, recorded path in the a.out.
You can specify more than one shared library oldpath:newpath, but each must be
preceded by the
+cdp option.
+cg pathname Specify the use of pathname as the code generator for compiling ISOMs to SOMs.
See the discussion of profile based optimization in the HP-UX Linker and Libraries
Online User’s Guide for more information.
+dpv Display verbose messages regarding procedures which have been removed due to
dead procedure elimination. The symbol name, input object file, and the size (in
bytes) of the deleted procedure are displayed. The total size (in bytes) of the deleted
procedures is also displayed.
+ea filename Exports all the symbols in the file filename .
+gstbuckets size
Request a particular number of buckets per entry using the global symbol table
hash mechanism. The default value is 3. The value can be overridden at runtime
by setting the _HP_DLDOPTS environment variable to the value -
symtab_buckets number. You can set the value using
chatr +gstbuckets
size file.
+nosmartbind
Disable SmartBind when binding a shared library. With this option enabled, the
linker places all symbols in the link into a single SmartBind module instead of plac-
ing each .o file in its own module.
+plabel_cache
Enable the plabel caching mechanism. Use this option with the +gst option.
This option is only effective with C++. In C++ applications, the dynamic loader
needs to repetitively access
PLABEL information (import stub). In order to make
this access faster, the dynamic loader uses the global symbol table structure to also
contain PLABEL entries. This behavior is enabled when the PLABEL_CACHE flag
is set in the dl_header structure (enabled ld +plabel_cache enable a.out
or chatr +plabel_cache enable a.out).
PA-RISC 64-Bit Options
-emit_relocs
Preserve compiler generated relocation sections in output file
-k filename Specify a mapfile that describes the output file memory map.
The user specified mapfile specifications are permitted 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 incremental link is performed automati-
cally.
