ic960 Compiler Driver
Option Arguments and Syntax
Some compiler driver options take arguments. Whitespace is optional
between an option and its argument. Case is significant in options and
arguments.
The options and arguments have default settings. In most cases, the option
is "off," that is, not in effect. Default settings of options and arguments
are summarized in Table 3-3 and further discussed in the detailed
description of the option. Some option defaults are affected by
environment variables, as noted in the option descriptions.
This chapter uses the following notation:
[ item ]
. . .
If two or more options contradict each other, the right-most option in the
command line takes precedence. For example, the following command
line sets the value of the symbol
ic960 -DL=80 -DL=132 proto.c
