As I worked through changes to another PR (https://github.com/llvm/llvm-project/pull/74912), I couldn't help but rewrite a few methods for readability, maintainability, and possibly some behavior correctness too. 1. Exiting early instead of nested `if`-statements, which: - Reduces indentation levels for all subsequent lines - Treats missing pre-conditions similar to an error - Clearly indicates that the full length of the method is the "happy path". 2. Explicitly return empty Value Object shared pointers for those error (like) situations, which - Reduces the time it takes a maintainer to figure out what the method actually returns based on those conditions. 3. Converting a mix of `if` and `if`-`else`-statements around an enum into one `switch` statement, which: - Consolidates the former branching logic - Lets the compiler warn you of a (future) missing enum case - This one may actually change behavior slightly, because what was an early test for one enum case, now happens later on in the `switch`. 4. Consolidating near-identical, "copy-pasta" logic into one place, which: - Separates the common code to the diverging paths. - Highlights the differences between the code paths. rdar://119833526 |
