LWDR - Light Weight D Runtime

What is this?

This is the light weight D runtime - it is a barebones runtime targeting ARM Cortex CPUs. It works by abstracting hooks that the user can connect to their selected backend (be it an RTOS such as FreeRTOS, ChibiOS, etc or a minimalist system).

What works?

1. Class allocations and deallocations (via new and delete)
2. Struct heap allocations and deallocations (via new and delete)
3. Invariants
4. Asserts
5. Contract programming
6. Basic RTTI (via TypeInfo stubs)
7. Interfaces
8. Static Arrays

What is in progress?

1. Exceptions and Throwables (so far are currently working)

What doesn't work?

1. Arrays
2. Module constructors and destructors
3. ModuleInfo

Has this been run on real hardware?

Yes, as of currently it has been run on an STM32F407.

What is untested?

1. Virtual functions and overrides
2. Abstract classes
3. Static classes

How to use this?

You have to hook the functions declared in rtoslink.d by implementing them in your MCU development environment. For example, with FreeRTOS, rtosbackend_heapalloc points to a wrapper in the C/C++ land that wraps pvPortMalloc(...).
