Hi, Cross Translation Unit (CTU) static analysis on master(trunk) reached a milestone. Now we can CTU analyse a not trivial C project - TMUX in this case - without any crashes. We are preparing a buildbot which does this analysis of TMUX with the help of CodeChecker (https://github.com/Ericsson/codechecker/). We would like to include this bot in the network of llvm buildbots during the following weeks.
We are getting closer and closer to be able to CTU analyse complex C++11 projects with the master branch. But before that, there are more patches to create and commit. This work is hard and slow, because most of the patches target the ASTImporter which is used in LLDB too, but with different parameters and set up. And of course we don't want to create regression for the LLDB folks. So, sometimes this work does involve creating LLDB patches as well. We continuously develop the ASTImporter in our fork, and we prepare patches for LLVM master. However, our fork will be always ahead of the LLVM master. Currently, we plan to create 30 more patches, and 6 are already on Phabricator. I you are interested about what do we plan to upstream have a look at here: https://github.com/Ericsson/clang/projects/2. If you'd like to get the full power of CTU analysis you should really try our fork: https://github.com/Ericsson/clang . We recommend to use it together with CodeChecker, since the scan-build script is abandoned. Our fork can analyse complex C++11(14) projects like bitcoin and protobuf without crashes. Currently we work on the analysis of LLVM/Clang itself, atm we fail to analyse 39 TUs out of ~2000. We regularly test and ship CodeChecker with this fork to our internal customers; there are dozens of projects which use the CTU analysis. Note that, however, all our projects are on Linux, so we focus on Linux. Currently the fork is based on Clang7, but soon we'll start rebasing to Clang8.
