If I'm not mistaken you may be referring to the files under Postfix
src/util which provide various abstraction layers? I faced similar
challenges, one of my hobbies is documenting bare metal programming for
obsolete architectures like SPARC V9:

Building a freestanding GCC cross-compiler is relatively simple, but I
prefer not to bring in open-source libc implementations since POSIX
compliance isn’t necessary for my use case. Instead, I’m progressively
developing my own routines for memory management, string manipulation,
and a range of fundamental algorithms and data structures. Without
these abstractions, programming in a freestanding C environment becomes
quite tedious.

This is where Ada really shines. With a supported runtime, such as the
Ravenscar Profile or Jorvik Profile, you effectively get a lightweight
RTOS built into the language itself. Unfortunately, there doesn’t seem
to be a runtime available for SPARC V9 yet.
