Overview

Expert skill for custom memory allocator design optimized for language runtime needs.

Capabilities

Implement bump/arena allocators
Implement free-list allocators with size classes
Design slab allocators for fixed-size objects
Implement thread-local allocation buffers (TLAB)
Handle large object allocation strategies
Implement memory pooling and recycling
Design memory profiling and statistics
Implement address space layout optimization

Target Processes

memory-allocator-design.js
garbage-collector-implementation.js
interpreter-implementation.js
bytecode-vm-implementation.js

Dependencies

jemalloc, tcmalloc references

Usage Guidelines

Size Classes: Design size classes to minimize internal fragmentation
Thread Safety: Use thread-local allocation for hot paths
Large Objects: Handle large objects separately from small allocations
Profiling: Build allocation statistics from the start
GC Integration: Design allocator API with GC integration in mind
