void ImplicitDepLoader::CreatePhonyInEdge ( Node *  node )

private

If we don't have a edge that generates this input already, create one; this makes us not abort if the input is missing, but instead will rebuild in that circumstance.

Load implicit dependencies for edge from a depfile attribute.

Returns

false on error (without filling err if info is just missing).

bool ImplicitDepLoader::LoadDeps	(	Edge *	edge,

Load implicit dependencies for edge.

May fill in mtime with the timestamp of the loaded information.
