User Commands (c) c89(1)

-Weld="args"

Passes the arguments speciﬁed in args to the eld utility after any other arguments are

passed. This ﬂag is valid only for TNS/E-targeted compilations.

Use this ﬂag to pass arguments to eld when creating a PIC ﬁle. c89 does not check the

validity of eld arguments.

You can only use this ﬂag when you use one of the following ﬂags:

-Wcall_shared or -Wshared

This ﬂag is ignored when the command does not initiate linking.

-Weld_obey="file"

Directs the eld utility to read additional command-line arguments from the command

ﬁle speciﬁed in the ﬁle argument. The arguments are processed as if they had been

passed directly to eld in place of ﬁle. c89 does not verify the existence or readability

of ﬁle.

The -Weld_obey ﬂag is valid only for TNS/E-targeted compilations. You can only use

this ﬂag if you use one of the following ﬂags:

-Wcall_shared or -Wshared

This ﬂag is ignored when the command does not initiate linking.

-Wenv=env

Speciﬁes the run-time environment. env can be one of common, embedded, library,

or libspace. The default value is common.

-Werrors=e

Stops compiling when e errors have been encountered.

-W[no]extensions

Enables [disables] HP extensions. If -Wextensions is speciﬁed, c89 also deﬁnes the

_TANDEM_SOURCE feature-test macro. The default value is -Wnoextensions.

-Wextern_data={no_gp | gp_ok}

Determines the addressing method for external data references (objects declared

extern). The default value is no_gp. This ﬂag applies to TNS/R-targeted compilations

only.

Setting gp_ok speciﬁes that external data references use GP-relative addressing.

GP-relative addressing can increase program performance. gp_ok cannot be speciﬁed

for native user libraries or when the -Wcall_shared or -Wshared ﬂag is used.

-Wfieldalign=align

Speciﬁes the ﬁeld alignment for structures. align can be one of auto, cshared2,

shared2, shared8,orplatform. The default value is auto. You cannot specify a

struct tag with this ﬂag.

-Wforce_vtbl | -Wsuppress_vtbl

Controls whether virtual function tables are created in cases where the compiler cannot

determine the need for the tables.

The virtual function table for a class is deﬁned in a compilation if the compilation con-

tains a deﬁnition of the ﬁrst noninline, nonpure virtual function of the class. For

classes that contain no such function, the default behavior is to deﬁne the virtual func-

tion table (but to deﬁne it as a local static entity).

The ﬂag -Wsuppress_vtbl suppresses the deﬁnition of the virtual function tables for

such classes, and the ﬂag -Wforce_vtbl forces the deﬁnition of the virtual function
