Modern special function register abstraction
summary
Claims a zero-cost C++ register abstraction built with heavy template metaprogramming that generates efficient code instead of relying on volatile, using an apply meta-function pattern to sort and merge accesses, exploit load multiple/store multiple, bit-banding and exclusive load/store or IRQ masking for atomicity. Reports concrete results: ported vendor code yields up to 10x flash shrink and about 2x runtime speed in places, provides a unit-test seam for desktop development, and the generated code actually works on hardware.
