Sure, but ARM's thumb has shown that you can get a RISC which has the same code density as current CISCs.

Of course, it's because current CISCs are bad due to backward compatibility but..

Yes, that's expected and no not "regardless of implementation": the GC implementation CAN be improved.

I remember a research paper about swap and GC, where the GC cooperated with the OS to avoid this kind of issue. AFAIK it went nowhere, too bad.

Are you talking about this one? https://cse.buffalo.edu/\~mhertz/bc-pldi-2005.pdf. If so, yes. Too bad. I don't know the repercusions this paper had in the past, though, in the sense of pros and cons of the bookmark collector. Don't know if anyone tried to actually implement it or design it at some point.

Yes, congratulations for finding it. And I don't know either,. Except that they did implement it on Linux (of course) https://plasma.cs.umass.edu/emery/cooperative-memory-managem...

Well let's not forget that early phone communication quality was ahem not-very-good, so of course errors were an issue.

The problem is the "exclusive access to it", most language aren't Rust.. Some Ada-implementation has the problem ( https://news.ycombinator.com/item?id=43001394 )

The OS write unused memory pages to the swap file by default. But the 'constant memory' design is usually done with locking in memory both the executable and memory pages (also pinning the process to CPUs, using realtime priorities etc).

-IDEs are more resources hungry, I remember when trying to use CLion on a big C++ codebase, until increasing the garbage collector maximum heap size all I had was a blank screen, after it was just unusably slow...

-even when IDE work, LSP for C++ codebase aren't very good, for example the caller hierarchy is usually very incomplete..

-I remember having been asked quite a few times, about "how do I use the IDE's integrated debugger to debug a target which was available only through ssh and then you had to telnet from one board to another?" My answer? Use gdb.

That said, I use VSCode now because its multiple tab handling is very nice, but I use it mostly as a glorified text editor (not by choice but because C++ is really IDE's unfriendly).

Well, it depends on the language: language which "capabilities" (both for the source code and for the building* ) could in theory really reduce a lot of the burden to identify supply chain attacks.

*: some research language have/had capabilities which would make supply chain attack "obvious" but for build systems I don't know if this exist.

Also the 60bit format will really help for loading immediates..

That said I wonder why normal ISA do not contain a 'Load Immediate on Next PC'? And if you want to allow parallel decoding the first byte of the immediate would be a 'special noop' and the first immediate byte would be inside the Load Immediate Next PC instruction instead.

That's not my experience: I've seen an LLM generate a C++ use-after-free (1.5 month ago).

But .. your language mostly hide when you're doing an 'inside' function call or an 'external' function call. I'm not sure I like this; 1) the latency of both operation is very different so you want to minimise the number of 'external' function calls 2) what happens in case of 'timeout' for external function calls? I didn't see it in the doc, did I miss it?

And at the same time, they make bigger and bigger cars which make more serious accidents for pedestrian, young children, etc.

So I think the best thing is to get news from everywhere Russia, China, the US, Europe, but that's a lot of work..
