Fundamental types, GCC built-ins, and base packages for Ada projects

#a0b #types #builtins

The a0b_base crate provides the root package hierarchy and foundational components tailored for low-level, embedded, and bare-metal Ada applications.

Key features include:

  • Foundational Numeric Types (A0B.Types):
    • Fixed-size Integer_* and Unsigned_* types (1 to 64 bits).
    • Bitwise shift and rotate operations for 8, 16, 32, and 64-bit unsigned types.
  • Array & Enumerable Utilities:
    • Unsigned_*_Array types in A0B.Types.Arrays.
    • Non-arithmetic modular index types (2 to 8 bits) for case statements and indexing in A0B.Types.Enumerable.
  • Low-Level & Protocol Utilities:
    • Big-endian integer and unsigned types (A0B.Types.Big_Endian, sizes 16 to 64-bit) for wire-format protocols.
    • SVD2Ada support types and definitions in A0B.Types.SVD.
  • Memory & Storage Abstractions (A0B.Storage):
    • Foundational memory views, explicit alignment management, and address/storage offset definitions for bare-metal drivers.
  • Compiler & Target Optimization:
    • Direct bindings to GCC intrinsics (bswap, clz, ffs, etc.) in A0B.Types.GCC_Builtins.
  • Build & Runtime Configuration:
    • Exposes the a0b_base.tasking build variable to seamlessly propagate Ada tasking mode capabilities (none, ada, a0b) across dependent crates.
