Pointers and Language Specifications in Programming

Viewed 169
This post discusses the complexities surrounding pointers in programming, particularly in the context of the C language. It highlights how pointer aliasing and optimizations lead to undefined behavior (UB) in certain conditions, and critiques the language specifications that govern such behaviors. The comments reflect on advancements made in languages like Rust regarding memory models, particularly focusing on pointer provenance and its impact on safe memory operations. A key point raised is the tension between performance optimizations in C versus maintaining well-defined behaviors, and the issues caused by strict aliasing assumptions. Moreover, the discourse mentions the need for clearer language specifications to avoid vulnerabilities in pointer handling.
