(1) Decided to release the source code for my LLVM-based static binary analysis framework ( https://t.co/xEgouoAkWS). It implements, among other things, an iterative control flow graph reconstruction algorithm heavily inspired by SATURN, using Remill and Souper.

@Microsoft It seems that Intel CPU specific settings were also applied in AMD CPUs and this piece of code is now wrapped with an "if" statement.

In recent ntoskrnl.exe update from KB5041587 @Microsoft introduced "Feature_Servicing_AmdDisableEarlyIBPB__private_IsEnabledDeviceUsage" and enables IBPB later on in the KiUpdateSpeculationControl function. Wondering why this gives a huge performance boost on >=Zen3 CPUs ?!

OH FOR CHRIST'S SAKE
Now I can't help but wonder - could Midnight Club II be affected too? AFAIK it has no known breakages like this, and the "saving softlock" is a legitimate game bug.

This challenge was uploaded by @JonathanSalwan, and I thought it was a good challenge to try myself and write about the solution. I think this challenge was done by @mr_phrazer. I have also played with frameworks like LLVM IR (@llvmorg) and SiMBA++ by @Blips_and_Chitz
