The problem Walter pointed to is that due to integer
promotion, arithmetic operands of types smaller than int are
converted to int, hence even if you use bytes and shorts you
would end up using ints, which are expensive on CPUs with no
native 32-bit registers. In theory, you could write your code
so that it's easy for the optimizer to prove that you're only
using 8 or 16 bits and variables would fit in single
registers, so you would be able to get away without a
performance penalty for using a language where ints are 32-bit.
Ah, that makes sense. Thanks for clarifying. For me it hasn't
proved a problem, but I could see it being if you do a lot of
arithmetic with 16-bit integers.
I just want to point out, that my impression is that the maker
scene
using all this 16 bit Arm Arduino and what ever micro controllers,
would be happy to have D as an alternative for coding in C.
So BetterC and D_16 might attract a way bigger community than many
other might think. Even if this reduced language might need to be
named D-- :-).
