At least the time of checking whether the compiler produced the correct code is mostly over. Back in the 1980s, it was very common that the PC-based compilers (I think we had a whole bunch, MS, Borland, Lattice,...) just generated the wrong code, typically in optimizing but due to the constrained memory we almost always needed size optimization (our case, M model, 64k code, >64k for data).

@lupyuen If a quadcopter endangers personnel, then I would hate to see what kind of threat the actual fire, soot and hot air pose.
The article is very dismissive of the people who risk their property and freedom for information that could be shared IRT with firefighting efforts.

Star64 #JH7110 triggers too many UART Interrupts on Apache #NuttX RTOS ... Let's find out why
Article: https://lupyuen.codeberg.page/articles/plic.html#spurious-uart-interrupts
Apache #NuttX RTOS runs in Supervisor Mode ... So we delegate #RISCV Interrupts from Machine Mode to Supervisor Mode

Although I have appreciated her content from time to time, the fact is that she quite openly broke China's Law and got off much milder than many anonymous "rebels" that use VPNs.
I think authorities "let her be" for much longer because of her mainly soft criticism of China itself, and her focus on DIY, at least initially. Could well be that her recent "coming out" was a step to far, perhaps the accumulation of tweets were no longer acceptable. Perhaps it was simply "reel in success"
