* [analyzer] Assign truly stable identifiers to exploded nodes.Artem Dergachev2019-10-171-5/+9
| | | | | | | | | | | 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 Dergachev2019-07-031-0/+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 checker messages.Artem Dergachev2019-07-031-0/+1
| | | | | | | | They are displayed as raw lines and diffed via difflib on a per-checker basis. Differential Revision: https://reviews.llvm.org/D64100 llvm-svn: 364989
* [analyzer] exploded-graph-rewriter: Add support for objects under construction.Artem Dergachev2019-07-021-0/+1
| | | | | | | | This trait is Environment-like, so there was a chance to re-use a lot of code. Differential Revision: https://reviews.llvm.org/D64047 llvm-svn: 364880
* [analyzer] exploded-graph-rewriter: Add support for dynamic types.Artem Dergachev2019-07-011-0/+1
| | | | | | | | | Slightly cleanup emission of horizontal lines and unhardcode the title for generic maps. Differential Revision: https://reviews.llvm.org/D64041 llvm-svn: 364865
* [analyzer] exploded-graph-rewriter: Add support for range constraints.Artem Dergachev2019-06-251-0/+27
Diff support included. A cheap solution is implemented that treats range constraints as "some sort of key-value map", so it's going to be trivial to add support for other such maps later, such as dynamic type info. Differential Revision: https://reviews.llvm.org/D63685 llvm-svn: 364268
