+v[no]shlibunsats
Enable [disable] printing a list of unsatisfied symbols used by shared libraries. The
default behavior in shared library build is +vnoshlibunsats
, and the default in
executable build is
+vshlibunsats
. Some unsatisfied symbols reported by the
linker are not required at run time because the modules which reference the symbols
are not used.
+vtype type Produces verbose output about the link operation. type can have the following values:
all Dumps all of the information from the
+vtype options. Same as -v.
files Dump info about each object file loaded.
heap Dump info about the size of the heap used by a link.
libraries Dump info about libraries searched.
procelim Dump info about sections that have been eliminated by the
+Opro-
celim
option
sections Dump info about each input section added to the output file.
symbols Dump info about global symbols referenced/defined from/in the input
files.
+FP flag Specify how the environment for floating-point operations should be initialized at pro-
gram start-up. By default, modes are specified by the IEEE floating-point standard:
all traps disabled, gradual underflow, and rounding to nearest. The +FP option sup-
ports the following modes (upper case flag enables; lower case flag disables):
D (d) Enable sudden underflow (flush to zero) of denormalized values.
I (i) Trap on floating-point operations that produce inexact results.
N (n) Trap on Denormal|Unnormal operand floating-point operation.
O (o) Trap on floating-point overflow.
U (u) Trap on floating-point underflow.
V (v) Trap on invalid floating-point operations.
Z (z) Trap on divide by zero.
RU Enable rounding upward (toward +Infinity).
RD Enable rounding downward (toward -Infinity).
RZ Enable rounding toward zero (truncate, chop).
RN Enable rounding to nearest (the default).
More than one mode can be specified with a comma separated list. For example:
+FP D,O,V,RZ
specifies sudden underflow, trapping on overflow and invalid, and rounding toward
zero. The commas and the space between +FP and the modes may be omitted. Thus,
+FPDOVRZ is equivalent to +FP D,O,V,RZ.
To dynamically change these settings at run-time, see fesettrapenable(3M),
fesetflushtozero(3M), and fesetround(3M).
+I function Specify the name of the initializer function when building a shared library. A shared
library may have multiple initializers specified. Initializers are executed in the order
that they are specified on the command line.
You can specify more than one initializer function on the command line with multiple
option-symbol pairs, that is, each initializer you specify must be preceded by the +I
option.
This option is supported for compatibility. Use of the +init and +fini options is
recommended. For more details on the initializer function, use the +help option or
see the HP-UX Linker and Libraries User’s Guide manual.
+O[no]fastaccess
This option is ignored.
