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.
