111
## This rule will get called only when MAKE decides that one of the
112
## targets needs to be created or re-created, because:
114
## * The .i file is newer than any or all of the generated files;
116
## * Any or all of the .cc, .h, or .py files does not exist and is
117
## needed (in the case this file is not needed, the rule for it is
120
## * Some SWIG-based dependecy of the .cc file isn't met and hence the
121
## .cc file needs be be regenerated. Explanation: Because MAKE
122
## knows how to handle dependencies for .cc files (regardless of
123
## their name or extension), then the .cc file is used as a target
124
## instead of the .i file -- but with the dependencies of the .i
125
## file. It is this last reason why the line:
127
## if test -f $@; then :; else
129
## cannot be used in this case: If a .i file dependecy is not met,
130
## then the .cc file needs to be rebuilt. But if the stamp is newer
131
## than the .cc file, and the .cc file exists, then in the original
132
## version (with the 'test' above) the internal MAKE call will not
133
## be issued and hence the .cc file will not be rebuilt.
135
## Once execution gets to here, it should always proceed no matter the
136
## state of a stamp (as discussed in link above). The
137
## $(DEPDIR)/trellis-generate stuff is used to allow for parallel
138
## builds to "do the right thing". The stamp has no relationship with
139

140
## the protection of multiple builds during a given call to MAKE.
