#include <stdlib.h>
// This function is used in vtables to point at pure virtual methods.
// The implementation in the standard library usually aborts, but
// the function is normally never called (a call would be a bug).
// Each of these entries in vtables, however, require an unnecessary
// dynamic relocation. Defining our own function makes the linker
// point the vtables here instead of the standard library, replacing
// the dynamic relocations with relative relocations.
//
// On Windows, it doesn't really make a difference, but on macOS it
// can be packed better, saving about 10KB in libxul, and on 64-bits
// ELF systems, with packed relative relocations, it saves 140KB.
//
// Another advantage of having our own is that the abort() will fall
// back to our own abort() rather than the system's.
