Control contents The A (Architecture), Fcoff | Felf (Object-
of generated object format),
F (Fine-tune), f (Optimize), g (Debug),
code
G (Generate), and O (Optimization-level) options
control the instruction set, object format, debug
information, and optimization level.
Assembler and The
W (Pass) option relays options to the
linker support preprocessor, compiler, assembler, and linker. In
addition, ic960 recognizes some options as linker
options rather than compiler options. Table 3-1
lists the options that are relayed to the linker
without the Pass option. For more detailed
information on linker options, see the i960
Processor Software Utilities User's Guide.
Whole-program The
fdb (Program Database), fprof
optimizations (Instrumentation), and gcdm (Decision Maker)
options allow for creation and use of information
necessary for advanced optimizations involving
multiple modules and optional execution profiles.
See Chapter 4 for an overview of whole-program
and profile-driven optimization.
Provide Information The
w (Diagnostic) and a (ANSI) options
on the compiling affect messages the compiler produces about
process C syntax and semantics. The
z (List) and Z
(Listname) options specify the contents and
name of the listing file. The
v (Verbose), V
(Version), and v960 (Version-exit) options
display information about preprocessor,
compiler, assembler, and linker options. The
Version option displays the versions of each
compilation component and the host operating
system. The
W (Warnings) option allows fine
control of the level of warnings emitted.
