Even from this tiny amount that I wrote, if you had had experience of
a more general nature but good embedded experience all the same with
various PC compilers, you'd have known that in a custom, non-PC system
there would _have_ to be custom assembly code, as well. Even knowing
nothing at all about the product I was talking about, it should be
amply clear from what I wrote that this would need to be the case. If
nothing else, in the crt0.asm code that was used. But in any real,
practical system, probably more than that.

Frankly, only with what I'd already written, I cannot see a reasonable
way to understand how you could make such a comment. That is, if you
had honestly had any practical experience with real clients and real
client motivations, in this regard. But I really wish you could have
been present at several meetings about this product, so I could have
watched you suggest it there. ;)

There are many products, both hardware and software, out there that
should last forever, but haven't or won't because of tool
obsolescence.

Yes. I've seen exactly that happen, in fact.

Many were developed in the days when, if you needed
a tool, you built it. Many of my systems were build around my own
relocatable object format, which was developed when Intel refused
to publish theirs. This long preceded the 8086, and by the time
they had changed their minds I had a better and locally entrenched
format. Now I am probably the only one who even remembers it.

hehe. In the case I had cited re: 8088, there are some custom tools
to convert certain fields so that one tool's OBJ format was compatible
with another tool's. It's life in embedded work.
