30 Pascal 4.0 User’s Guide

The default is -fround=nearest.

The meanings are the same as those for the ieee_flags subroutine.

If you compile one routine with -fround=r, compile all routines of the

program with the same –fround=r option; otherwise, unexpected results may

occur.

–ftrap=t

(Solaris 2.x only) The -ftrap=t option sets the IEEE 754 trapping mode in

effect at startup.

t is a comma-separated list of one or more of the following: %all, %none,

common, [no%]invalid, [no%]overflow, [no%]underflow, [no%]division,

[no%]inexact. The default is -ftrap=%none.

This option sets the IEEE 754 trapping modes that are established at program

initialization. Processing is left-to-right. The common exceptions, by deﬁnition,

are invalid, division by zero, and overﬂow.

Example: -ftrap=%all,no%inexact means set all traps, except inexact.

The meanings are the same as for the ieee_flags function, except that:

• %all turns on all the trapping modes.

• %none, the default, turns off all trapping modes.

• A no% preﬁx turns off that speciﬁc trapping mode.

If you compile one routine with -ftrap=t, compile all routines of the program

with the same -ftrap=t option; otherwise, unexpected results may occur.

-G

(Solaris 2.x only) The -G option builds a shared library. All object ﬁles speciﬁed

with this command option should have been compiled with either the -pic or

the -PIC option.
