28 Pascal 4.0 User’s Guide

–dalign

The –dalign option instructs the compiler to generate double load and store

instructions wherever possible for faster execution. All double-typed data

become double-aligned, so do not use this option when correct alignment is

not ensured.

-dn

(Solaris 2.x only) The -dn option speciﬁes static linking in the link editor.

-dryrun

The –dryrun option instructs the compiler to show, but not execute, the

commands constructed by the compilation driver. You can then see the order

of execution of compiler passes without actually executing them.

-dy

(Solaris 2.x only) The -dy option speciﬁes dynamic linking in the link editor.

–fast

(Solaris 1.x only) The –fast option selects optimum compilation options for

speed and provides close to the maximum performance for most realistic

applications. A convenience option, it chooses the fastest code generation

option available on the compile-time hardware, the optimization level -02, the

-dalign option, and a set of inline expansion templates. If you combine -

fast with other options, the last speciﬁcation applies.

(Solaris 2.x only) The -fast option includes -fns -ftrap=%none; that is, it

turns off all trapping. In previous releases, the -fast macro option included

-fnonstd; now it does not.

-fast includes -native in its expansion.

The code generation option, the optimization level, and using inline template

ﬁles can be overridden by subsequent switches. For example, although the

optimization part of -fast is -O2, the optimization part of -fast -03 is -03.
