Bug ID: 16822
Summary: Implement a minimal rebuild option
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

The Microsoft compiler supports this:
<http://msdn.microsoft.com/en-us/library/vstudio/kfz8ad09.aspx>.
I think this basically comes down to the compiler keeping track of where each
name in the preprocessing and semantic analysis phase is coming from (which
clang currently does), and using that information to decide whether a change in
a header file is going to change the declaration/definition of any of those
names and skip generating a new object file if that's not the case.
Does this make sense to implement in clang?
