ld_ia(1) Integrity Systems Only
ld_ia(1)
-C n This option is ignored and generates a warning message.
-D offset Set (in hexadecimal) the starting address of the data segment. This option is useful
with kernel and embedded applications. The default address for 64-bit mode is
0x6000000000000000 and the default address for 32-bit mode is 0x40008000.
-E Mark all symbols defined by a program for export to shared libraries. In a
+com-
pat mode link, ld marks only those symbols that are actually referenced by a
shared library seen at link time. In a
+std link, all symbols are exported by
default, so
-E is not necessary to make symbols visible. However, it has an addi-
tional side effect of identifying all exported symbols as necessary, so that they will
not be removed when using dead code elimination (
+Oprocelim).
-Fl Force load the archive library. Equivalent to
+forceload.
-Fw This option is ignored and generates a warning.
-Fz This option is accepted and ignored.
-G Strip all unloadable data from the output file. This option is typically used to strip
debug information and is incompatible with the
+ild option.
NOTE: Use of the
-G option might impair or prevent the use of a symbolic
debugger on the resulting program.
-I Instrument the code to collect profile information upon execution. When an instru-
mented program is executed, a profile database file is output (by default, named
flow.data). The profile data gathered during program execution can be used in
conjunction with the -P option. The default instrumenter is the dynamic instru-
menter /opt/langtools/bin/caliper
, but the +instrumenter option can
be used to invoke the static instrumenter
/opt/langtools/bin/sin
instead.
This option should not be used with the
-P, -O, +ild,or+O options.
NOTE: If using
+instrumenter sin
, the recommended method to instrument
your programs is to use your compiler’s
+I option, rather than the ld -I option. If
you invoke the linker directly, you must pass the
-u__sin_core__
,
-u__sin_init, and -lsin options to the linker. If you have both an instru-
mented shared library and an instrumented shared executable that you want to link
with that library, you must include the -h__sin_core__
and
-h__sin_lookup_ibt
options in addition to the -u options. If using the default
or
+instrumenter caliper, no additional linker options are needed.
-L dir Search for libx.a, libx.sl, or libx.so
, in dir before looking in default loca-
tions. You can specify more than one directory, but each must be preceded by the
-L option. The -L option is effective only if it precedes the -l option on the com-
mand line.
-N In 32-bit mode only, cause the data to be placed immediately following the text, and
make the text writable. Files of this type cannot be shared.
-O Turn on linker optimizations. Currently the optimization includes the removal of
dead procedures.
-O is passed to the linker by the compilers when the +O4 compiler option is
selected.
This option is incompatible with the
+ild option.
For more details on linker optimizations use the
+help option or see the HP-UX
Linker and Libraries User’s Guide manual.
-P Examine the profile database file produced by an instrumented program (see the -I
option) to perform profile based optimizations on the code. This option should not
be used with the +ild option.
-Pd Reorder debuggable functions. This option is enable by default.
Reordering is based on link order file produced from
flow.data by default. If you
specify the -PF option, the linker uses the specified link order file, instead of
flow.data, for reordering.
