The article discusses GCC's implementation of nested functions in C, explaining how they work without trampolines using wide pointers. It compares GCC's approach with C++ lambdas and explores the technical challenges of implementing nested functions in C, particularly regarding ABI compatibility and the static chain register.
Background
Nested functions are a common programming language feature that allows functions to be defined within other functions, but they are not part of the C standard. GCC provides them as an extension, while C++ implements similar functionality through lambda expressions with a different approach.
