Repository Details

Generic Ada Runtime CI

The generic Ada runtime is a downsized Ada runtime which can be adapted to different platforms. The offered feature set is a tradeoff between complexity and useful features.

Features

The runtime includes a variety of specs providing types and compiler intrinsics. It furthermore adds a small selection of more complex features:

  • Secondary stack
    • SPARK proof: no runtime errors, safe program abort in case of stack overflow, stack underflow or invalid stack count
  • 64bit arithmetic
    • SPARK proof: addition and subtraction with overflow check have no runtime errors, both functions perform a correct addition/subtraction
  • Exception support
    • Exceptions can only be thrown but not catched, there is only a last chance handler available

Platforms

  • Posix/Linux
  • Genode
  • nRF52832
  • STM32F051
  • ESP8266 on Arduino

Directory Structure

  • contrib/: external sources (GCC 8.3)
  • platform/: platform-specific sources of Ada runtime
  • src/: Ada runtime sources
  • tests/: test sources
  • build: platform specific build directories

Platform-specific Symbols

To enable a new platform for this runtime the platform needs to provide a set of linker symbols. Please have a look into the platform interface description.
