9.16.1 RTL Generation Tool Options for Directory Search

The `-Idir' option specifies directories to search for machine descriptions. For example:

 
genrecog -I/p1/abc/proc1 -I/p2/abcd/pro2 target.md

Add the directory dir to the head of the list of directories to be searched for header files. This can be used to override a system machine definition file, substituting your own version, since these directories are searched before the default machine description file directories. If you use more than one `-I' option, the directories are scanned in left-to-right order; the standard default directory come after.
