We use Makefile.depend (default value for # .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to # distinguish them from others. # # Before each Makefile.depend file is read, we set # DEP_RELDIR to be the RELDIR (path relative to SRCTOP) for # its directory, and DEP_MACHINE etc according to the . # represented by the suffix of the corresponding target. # # Since each Makefile.depend file includes dirdeps.mk, this # processing is recursive and results in .MAKE.LEVEL 0 learning the # dependencies of the tree wrt the initial directory (_DEP_RELDIR). # # NOTE: given the extent of processing that DIRDEPS undergoes it # is important that any variables in entries use :U to guard # against surprises when undefined. # # TARGET_SPEC_VARS # The default value is just MACHINE, and for most environments # this is sufficient.
