CC (continued)
-D name [=string]
Defines name to the preprocessor as if defined by a #define in each source file.
The form -D name sets name to 1. The form -D name = string sets name to the
given string.
-u name [=string]
Removes definition of name so that the preprocessor removes the name defined
by a #define in each source file. The form -U name sets name to 0. The form
-U name = string undefines name for the given string.
-1 pathname
Adds pathname to the list of directories to be searched when a #include file is
not found in the directory containing the current source file or whenever angle
brackets ( < >) enclose the filename. There is a standard list of directories which
is searched automatically.
-X Removes the standard directories from the list of directories to be searched for
#include files.
-V string
Copies string to the object file created from the given source file. This option
may be used for version control.
-W num
Sets the output level for compiler warning messages. If num is 0, no warning
messages are issued. If 1, only warnings about program structure and overt type
mismatches are issued. If 2, warnings about strong typing mismatches are
issued. If 3, warnings for all automatic conversions are issued. This option does
not affect compiler message output for non-warning messages.
-w Prevents compiler warning messages from being issued. Same as -W 0.
-p Adds code for program profiling. Profiling code counts the number of calls to
each routine in the program and copies this information to the mon.out file.
This file can be examined using the prof command. Profiling is supported only
in small model.
-pack Packs structure members. Caution should be taken when using the pack option
because structures are no longer word-aligned.
-i Creates separate instruction and data spaces for small model programs. When
-F num
B-22
the output file is executed, the program text and data areas are allocated
separate physical segments. The text portion will be read-only and may be
shared by all users executing the file. The option is implied when creating
middle, large, or huge model programs.
Sets the size of the program stack to num bytes. Default stack size if not given
is 4K bytes.
