Sam Blackshear 14aef012f6 [quandary] allow specifying globals as sources Summary: We supported globals as sources before, but we did so by allowing ClangTrace etc. to match against any access path in the footprint of the trace. This is very powerful/flexible, but it's ultimately not a good idea because it leads to traces that are hard to read. This is because a footprint source doesn't have any information about its provenance: we might know that the value came from a global, but we don't know where the read occurred. The mechanism for handling procedure calls as sources already knows how to solve this problem. This diff implements globals as sources as a special case of procedure call sources instead. This will give us much nicer traces with full provenance of the read from the global. Reviewed By: mbouaziz Differential Revision: D5772299 fbshipit-source-id: 491ae81		8 years ago

Intermediate Representation

The Intermediate Representation is a format used by the back-end for analysis. It is produced by one of the front-ends, one for each program analyzed.

The main entry point is the intermediate language in Sil.

The control flow graph module is Cfg.

The call graph module is Cg.

The type environment module is Tenv.
