Smaller debug info with constructor type homing
Constructor type homing for debug info Background Class type information is a large contributor to debug info size. Clang already has a few optimizations to reduce the size of class type information based on the assumption that debug info can be spread out over multiple compilation units.

The New Pass Manager
LLVM’s New Pass Manager What is a pass manager? A pass manager schedules transformation passes and analyses to be run on IR in a specific order. Passes can run on an entire module, a single function, or something more abstract such as a strongly connected component (SCC) in a call graph or a loop inside of a function.

Cling -- Beyond Just Interpreting C++
Interactive C++ with Cling In our previous blog post “Interactive C++ for Data Science” we described eval-style programming, interactive C++ in Notebooks and CUDA. This post will discuss some developed applications of Cling supporting interoperability and extensibility.

LLVM meets Code Property Graphs
The code property graph (CPG) is a data structure designed to mine large codebases for instances of programming patterns via a domain-specific query language. It was first introduced in the proceedings of the IEEE Security and Privacy conference in 2014 (publication, PDF) in the context of vulnerability discovery in C system code and the Linux kernel in particular.

Bringing Stack Clash Protection to Clang / X86 — the Open Source Way
Context Stack clash is an attack that dates back to 2017, when the Qualys Research Team released an advisory with a joint blog post. It basically exploits large stack allocation (greater than PAGE_SIZE) that can lead to stack read/write not triggering the stack guard page allocated by the Linux Kernel.
