FYI: Embedded C++

FYI: Embedded C++

[Ken Garlington]

In the November 1996 Embedded Systems Programming magazine, P. J.
Plauger states that a committee primarily composed of Japanese companies 
(NEC, Toshiba, etc.) is working on the development of a language called 
Embedded C++ to "address the needs of developers who wish to produce 
embedded systems in C++.... The easiest way to describe Embedded C++ as 
a language is in terms of what it doesn't have. The committee began with 
the draft C++ Standard and removed certain features. A feature was a 
candidate for removal for any of several reasons:

"* Exceptions were omitted because of the added runtime overheads in 
calling functions, in some cases even when code makes no direct use of 
exceptions

"* Multiple inheritance and virtual base classes were omitted because 
they too add overheads even for code that makes no direct use of these 
features

"* Templates were omitted because of the potential for code explosion

"* Namespaces were omitted because their added complexity does not 
appear to have an adequate payoff in embedded applications

"* Runtime type identification was omitted for much the same reason that 
namespaces were"

Just thought people might be interested. (Did anyone else experience 
deja vu while reading this?)

It's interesting what people consider to be "unnecessary".  I guess if
all you do is washing-machine and microwave software, then support for
programming-in-the-large is not that important...
