Understanding Fil-C: A simplified memory-safe model for C/C++ with a GC
Summary
The article describes a simplified Fil-C model that rewrites C/C++ code to add AllocationRecord lifecycle management for pointer-safe operations and uses a garbage collector to reclaim memory. It explains per-function pointer local variables becoming heap-allocated under certain conditions, bounds checks on dereferencing, and how memmove interacts with tracked memory. It also outlines production-quality considerations (threads, function pointers) and suggests use cases for adopting Fil-C as a memory-safety measure.
