BCC64X
Go Up to Clang-enhanced C++ Compilers
BCC64X is a RAD Studio C++ compiler for 64-bit Windows.
BCC64X is based on Clang. For more information about what the BCC64X compiler has in common with other Clang-enhanced C++ compilers, see Clang-enhanced C++ Compilers.
Note: For 32-bit Windows, use BCC32C (Clang-enhanced compiler) or BCC32 (previous-generation compiler).

Toolchain
The Windows 64-bit Modern C++ toolchain (bcc64x) is an entirely new implementation of the Clang extensions and C++Buidler features with new, platform-standards technology. Besides, it is our recommended C++ toolchain for use.
It uses the LLVM libc++ STL, a custom C++ RTL, the Windows UCRT for the C runtime, and emits object files in COFF64 format with PDB debug info.
To add this toolchain to your existing C++ project, perform the following steps:
- Right-click the Target Platforms node in the Projects treeview.
- Select Add Platform.
- Choose Windows 64-bit (Modern).
Note: You can toggle between the old and new Win64 platforms easily because both are installed and can be added to a project side by side, allowing easy upgrading.
