Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.

- rebase on top of current master
- interleave DIRS-* and DEPDIRS-* targets for more readability

Hi Olivier,

Thanks again for this. I only have minor cosmetic remarks:

Le 17 mars 2017 18:13, "Olivier Matz" <olivier.matz@6wind.com> a écrit:

Maybe remove the comment line too?

Same here. There may be others.

Why change this line ?

Thanks, I'll check for other occurrences.

It's a typo, I'll remove it in v2.

Thanks for your review

-------------
-
-*   depdirs
-
-    This target is implicitly called by make config.
-    Typically, there is no need for a user to call it,
-    except if DEPDIRS-y variables have been updated in Makefiles.
-    It will generate the file  $(RTE_OUTPUT)/.depdirs.
-
-    Example:
-
-    .. code-block:: console
-
-        make depdirs O=mybuild
-
-*   depgraph
-
-    This command generates a dot graph of dependencies.
-    It can be displayed to debug circular dependency issues, or just to understand the dependencies.
-
-    Example:
-
-    .. code-block:: console
-
-        make depgraph O=mybuild > /tmp/graph.dot && dotty /tmp/ graph.dot
