Chrec: Move rtype Definition Closer to Its Use
The rtype variable in tree-chrec.cc is now defined only within the scope where it's actually used, improving code clarity.
This commit moves the definition of the rtype variable within the chrec_fold_plus_poly_poly function in tree-chrec.cc to the specific scope where it is used (only for POINTER_PLUS_EXPR). This improves code readability and reduces potential for misuse of the variable in other parts of the function.
In Details
In tree-chrec.cc, the definition of rtype is moved to the scope where it's actually used, specifically within the POINTER_PLUS_EXPR condition in chrec_fold_plus_poly_poly. This reduces scope and improves code clarity. The change has minimal impact but enhances maintainability.
For Context
The change history recorder (chrec) in GCC tracks how expressions change during compilation, enabling optimizations. This commit improves code organization by limiting a variable's scope to where it is used, making the code easier to understand and maintain. This has no direct impact on compiler behavior.
