[cfe-dev] A tool for generating reduced headers for test cases (delta debugging)

[Nikita Zhuk]

Hi,

Several clang analysis test cases written in ObjC contain the  
following comment line in their header: "These declarations were  
reduced using Delta-Debugging from Foundation.h on Mac OS X.". Are  
there some instructions about tools which should be used to generate  
such reduced headers? Being able to do so would make it possible to  
report bugs by using runnable test cases, and those test cases could  
be eventually included with the clang itself.
