Attendance: David, Shahzad, Vaibhav, Vassil

Vassil: Progress on modules on Windows: we have proposed a fix for the MSInheritanceAttr (https://reviews.llvm.org/D83174). In addition Vaibhav has identified another issue with the late template parsing where we see ClassTemplateSpecializations instead of only FunctionDecls. We enabled more modules and we are almost at the same green state as before. We discovered that the modules still have many duplicates due to the fact that boost modules are not reused (https://paste.ubuntu.com/p/krJJ6chZNc/) .

David: We discover problems with each batch of enabled modules. We find missing header guards or duplicate header classes. Matti fixed some issues we reported.

Shahzad: Last week I fixed could of issues wrt of CXXMODULES. I have merged the build rules for modules and standard cmssw.

Vaibhav: Nothing else to add.

Priorities: Keep the modules IB green-ish and enable 20 more modules; Get some performance measurements for the GMI.

Modules status in cmssw: 203/250.

AOB: Next meeting in two weeks
