Clean your build directory and re-configure: xplatcppwindowsdll updated

The updated toolchain integrates clang-cl with the latest Visual Studio 2022 (17.8+) to produce ARM64 DLLs that are up to 35% more efficient in emulated x86 scenarios. The biggest headache—exporting symbols—has been eliminated. The new version introduces a XPLATCPP_PUBLIC macro that works flawlessly across MSVC, Clang, and GCC. build/tools/xplatcpp_validate_dll

build/tools/xplatcpp_validate_dll.exe --dll build/Release/MyEngine.dll It will report if any symbols are unintentionally hidden or if the manifest is malformed. The xplatcppwindowsdll update has already been tested in three production environments. Use Case A: Game Engine Plugin System A mid-sized indie studio uses xplatcppwindowsdll to ship a C++ physics library as a DLL, loaded dynamically by a Unity game on Windows and Godot on Linux. The new update reduced their per-platform #ifdef code by 70% and allowed them to add ARM64 handheld support (e.g., ASUS ROG Ally) in under two days. Use Case B: Financial Tick Processing A trading firm wraps their cross-platform order management system in a DLL that gets called from Excel via VBA (yes, that still exists). The load-time profiling feature helped them discover a static mutex that was blocking initialization for 300ms. After fixing it, DLL load dropped to 12ms, improving spreadsheet responsiveness dramatically. Benchmarks The team behind xplatcppwindowsdll published before-and-after metrics using a 500k-line C++ codebase (compiled with MSVC 19.38, /O2): The new update reduced their per-platform #ifdef code

With ARM64 support, automatic visibility management, load-time profiling, and SxS manifest generation, this update empowers you to write clean, portable C++ code and still produce a first-class Windows DLL that feels native to the platform.
