The gcdm option is flexible and powerful, and therefore requires a certain
level of understanding in order to use it effectively. For these reasons, it is
documented in a separate chapter (Chapter 6) in this manual. Before using
the gcdm option, you should read Chapter 4, Program-wide Analysis and
Optimization, and become familiar with the information in Chapter 5,
Profile Data Merging and Data Format (gmpf960).
I (Searchinclude)
Specifies include file
directory.
I
directory
Adds
directory
to the end of the list of directories to be searched for
header files. This can be used to override a system header file,
substituting your own version, since these directories are searched before
the system header file directories. When you use more than one
I option,
the directories are scanned in left-to-right order; the standard system
directories come after.
I- | I. (Include-dash, Include-dot)
Controls search order
and paths.
I- | I.
Any directories specified with I options before the I- option are searched
only for
#include "
file
"; they are not searched for #include <
file
>.
When additional directories are specified with
I options after the I-, these
directories are searched for all
#include directives. (Ordinarily all I
directories are searched this way.)
