* [analyzer] exploded-graph-rewriter: Fix dump for state 0.Artem Dergachev2019-10-181-2/+2
| | | | | | It shouldn't say "unspecified" when the state is specified to be empty. llvm-svn: 375279
* [analyzer] Assign truly stable identifiers to exploded nodes.Artem Dergachev2019-10-171-4/+16
| | | | | | | | | | | ExplodedGraph nodes will now have a numeric identifier stored in them which will keep track of the order in which the nodes were created and it will be fully deterministic both accross runs and across machines. This is extremely useful for debugging as it allows reliably setting conditional breakpoints by node IDs. llvm-svn: 375186
* [analyzer] exploded-graph-rewriter: Implement bug nodes and sink nodes.Artem Dergachev2019-07-031-2/+2
| | | | | | | | | | | Add a label to nodes that have a bug report attached or on which the analysis was generally interrupted. Fix printing has_report and implement printing is_sink in the graph dumper. Differential Revision: https://reviews.llvm.org/D64110 llvm-svn: 364992
* [analyzer] exploded-graph-rewriter: Implement a dark color scheme.Artem Dergachev2019-07-021-2/+4
| | | | | | | | Addresses a popular request. Activated via --dark. Differential Revision: https://reviews.llvm.org/D64056 llvm-svn: 364882

| | | | | | | | | | buildbots." This reverts commit r362343. Instead, disable tests on Windows for now. llvm-svn: 362347
* [analyzer] exploded-graph-rewriter: Initial commit.Artem Dergachev2019-06-021-0/+12
This is a utility to improve readability and generally manipulate GraphViz dumps of the analysis graph. Such dumps are often huge and not only hard to read, but also often hang the viewer apps with their mere size. Such script should significantly improve debugging experience.
