Simplify code in `Rep_Item_Too_Late` with a membership test
The Ada compiler function `Rep_Item_Too_Late` was simplified using a membership test, improving readability without changing its functionality.
This commit introduces a minor code cleanup in the Ada compiler’s sem_ch13.adb file. The Rep_Item_Too_Late function, which likely handles checks related to representation items in Ada, has been refactored to use a membership test. This change makes the code more concise and readable without altering its original semantics or behavior, focusing purely on internal maintainability.
In Details
This change affects sem_ch13.adb, specifically simplifying the Rep_Item_Too_Late function. This function is part of the semantic analysis phase, likely pertaining to checks on 'representation items' which allow low-level control over object layouts. The simplification involves replacing existing conditional logic with a more compact membership test, leveraging Ada's in operator. This enhances code clarity and maintainability within the semantic checker without altering compiler behavior regarding representation item validity.
For Context
Compilers translate your human-readable code into instructions a computer can understand. During this process, they perform many checks to ensure your code follows the language's rules. This update is a small improvement to the Ada compiler's internal code. It simplifies a function called Rep_Item_Too_Late, which is part of the 'semantic analysis' phase – where the compiler tries to understand the meaning of your code. By using a 'membership test,' similar to checking if a value 'is in' a list of allowed values, the function becomes more straightforward and easier for compiler developers to read and maintain. This change does not affect how your Ada programs run; it merely makes the compiler's own code more efficient to manage.
