As far as I can tell, gotos are essential for maintainable c-code. In particular, having an end label in a function that handles freeing intermediate variables that may or may not have been allocated is vital for functions with multiple (logical) return points. As are fail labels where appropriate. Appropriate use of goto is literally written into the internal C style guide where I work. This is not about performance; it is entirely about avoiding memory bugs. Maybe this will go away when defer becomes a thing. But seeing as people still target C99, that might take a while. |
