Why is this limited to the preprocessor? I imagine the compiler proper could inline the compare function parameter into the qsort implementation body in the typical case, at the qsort() call site. (Assuming qsort's implementation was in a header, as the original comment posited).
- syockit 4y agoYou're right. I tried it here https://godbolt.org/z/457dYWfq5 https://godbolt.org/z/457dYWfq5 and if the generic function is visible to the call site and inlineable, then the compare function can be inlined too. I didn't know this, I had always thought that the semantics of function pointer prevented this from being achievable!
