First of all, I would like to thank everyone for their feedback on the last video. It was a very meaningful discussion. The performance of AC6 this time is astonishing; it can jump around even without optimization.
The purpose is to test the debugging phenomena in the C environment with the same program code.
IAR Version: 9.3xMDK Version: 5.3x, including AC5 and AC6Embedded Studio: Using GCC, Version V7.1X
The review process on Tencent Video is a bit slow, so I won’t wait. Here’s the link on Bilibili:

MDK AC6 without optimization, priority set to O0, debugging jumps around, which is unreasonable. This cannot be blamed on optimization issues, using AC6.18..
When set to O1 optimization, it can even execute in reverse order, animated effects:
