Revision 1.6, Sat Nov 24 15:41:01 2007 UTC (16 years, 6 months ago) by espie
Branch: MAIN
CVS Tags: OPENBSD_4_4_BASE, OPENBSD_4_4, OPENBSD_4_3_BASE, OPENBSD_4_3 Changes since 1.5: +1 -0 lines
more parallel make fixes.
Preparations to fix the engine:
- new function has_been_built(gn), that tells you what's the status of
a given node. Allows us to run Suff_FindDeps later, by updating the number
of unmade children correctly.
- take out the code that handles shell expansions in an expand_children*
set of functions, called by Suff_FindDeps, among others. These must be
called early in the engine to avoid creating bogus nodes.
Engine fixes:
- take the predecessor/successor special handling out, deal with it in
separate functions.
- don't count nodes. Explicitly track them all in a hash table (better
way to deal with non-built issues).
- don't run Suff_FindDeps at start, but just before building an actual node.
This allows make to find all dependencies correctly, as in groff.
Pfiou! now it works.

* The TARG_ constants are used when calling the Targ_FindNode functions.
* They simply tell the function what to do if the desired node is not found.
* If the TARG_CREATE constant is given, a new, empty node will be created
* for the target, placed in the table of all targets and its address returned.
* If TARG_NOCREATE is given, a NULL pointer will be returned.
