digitalmars.D.ldc - version (AVR)

reply =?UTF-8?B?Q2hsb8Op?= Kekoa <rightfold+ck gmail.com> writes:
I’m currently using D to program an ATmega328P microcontroller, 
which interprets the AVR instruction set. Works quite well, but 
there are some definitions missing from the core library, such as 
a definition for c_long, when compiling for AVR. This makes it 
impossible to import parts of the standard library that rely on 
these definitions being there.

I’d like to add the missing features to druntime, but this 
requires a version switch for AVR. Is there such a switch? If not 
I could add it to LDC, would “AVR” be a good name?

For instance, the following code currently compiles, but ideally 
shouldn’t:

version (AVR)
     static assert(false);

Using ldc2 -mtriple=avr-atmel-none -mcpu=atmega328p

Try a v1.22 beta, version (AVR) was added with beta1.

Also, for future reference, the table of predefined versions (not all 
necessarily implemented on LDC) can be found at 
https://dlang.org/spec/version.html#predefined-versions.

Thanks, will give that a try and see if I can add the definitions 
to druntime and import some more stuff from std. :)
