Dynamic Go Instrumentation for Production Environments
summary
A pure-Go compiler proxy is built that uses go tool exec to intercept each package compile, rewrite source with inserted prologue/epilogue hooks, emit a generated hook table, and forward to the real compiler and linker. Runtime API finds symbols by function name, atomically attaches callbacks that can abort calls or mutate return values. Demo instruments println, the build reports 123 hooks (and the main binary shows ~1,000+ hooks) and the demo output matches expectations.
