bfd: pe: Introduce COFF_WITH_pe32plus define
Define COFF_WITH_pe32plus for PE32+ formats to simplify conditional logic.
This patch introduces a new preprocessor macro, COFF_WITH_pe32plus, to consolidate checks for PE32+ (64-bit) formats within bfd/peXXigen.c. This aims to replace error-prone, long lists of specific format defines with a single, clearer indicator, making the code more maintainable and reducing the likelihood of errors when handling PE32/PE32+ differences.
In Details
This patch refactors bfd/peXXigen.c by introducing COFF_WITH_pe32plus. Previously, multiple COFF_WITH_pe* defines were used to distinguish PE32+ targets. This new macro simplifies conditional logic that differentiates between PE32 and PE32+ formats, making code that handles these differences more readable and less prone to copy-paste errors. It's a code hygiene improvement.
- PE32+
- A 64-bit version of the Portable Executable (PE) file format, commonly used for executables on Windows.
- preprocessor macro
- A directive in C/C++ code that the preprocessor expands before compilation, often used for conditional compilation or defining constants.
- conditional logic
- Code that executes different paths based on whether certain conditions are true or false, often implemented using
#if,#ifdef, etc.
