Hello C++ Developers, Embarcadero and Whole Tomato developer teams are working hard on to release of RAD Studio 12, and it seems like we may (or not) see the early released version of the new C++ compiler before 2024. The new 64-bit Clang Toolchain in RAD Studio 12 may have a new bcc64x C++ compiler. The news is amazing. Before it comes, let’s keep learning some modern C++ features to heat up from now on. This week, we have 3 more modern C++ features that can be used in C++ Builder. The concurrency support library in modern C++ is designed to allow your programs to read and write data securely in thread operations allowing us to develop faster multi-thread code. There are differences between mutual exclusion (std::mutex) and shared mutex (std::shared_mutex) and in another post, we explain these. The tuple (std::tuple) was introduced in C++11 and improved in C++14. In the last post, we explain tuple addressing via type features that come with the C++14 standard. Our educational LearnCPlusPlus.org site has a broad selection of new and unique posts with examples suitable for everyone from beginners to professionals alike. It is growing well thanks to you, and we have many new readers, thanks to your support! The site features a treasure-trove of posts that are great for learning the features of modern C++ compilers with very simple explanations and examples. RAD Studio’s C++ Builder, Delphi, and their free community editions C++ Builder CE, and Delphi CE are powerful tools for modern application development.

Secure your spot from this link now: https://ow.ly/NZFQ50PVL13 Some of the technical features are: Uses Clang 15 Uses LLVM’s lld as the linker Emits COFF64 object files (note this means Delphi can also emit COFF64 object files in 12.0: the compiler option “-jf:coff” is specified by our targets files when the “-JL” or “-JPHN[E]” options are specified) Emits PDB format debug info Uses the Itanium ABI (not Microsoft ABI) Uses LLVM’s libc++ STL Uses UCRT for the C runtime Uses a mix of LLVM and MinGW for the C++ runtime Targets Win64 Named bcc64x Here are more details about it, Win64 Clang Toolchains in RAD Studio 12 How to use modern C++ with C++ Builder? In modern C++, the concurrency support library is designed to solve read and write data securely in thread operations that allow us to develop faster multi-thread apps. This library includes built-in support for threads (std::thread), atomic operations (std::atomic), mutual exclusion (std::mutex), condition variables (std::condition_variable), and many other features.  In C++14, in addition to mutex, there is a shared_mutex which is an instance of the class located in  header. In the first post, we explain using shared mutexes locking in Modern C++. There are differences between mutual exclusion (std::mutex) which comes with C++11 and shared mutex (std::shared_mutex) which comes with C++14 standards. In the next post, we explain a frequently asked mutex question in modern C++, what are […]

Hello C++ Developers, this week, we have 3 more modern C++ features that can be used in C++ Builder. In C++14 you can store string in strings using modern programming methods. In the first post, we explain how you can preserve the string format especially when we use a string in a string with /”. Containers are powerful data storage arrays in modern C++ and they are very useful for iterating and searching data with their amazing methods and properties. In another post today we explain what the containers in modern C++ are, their types, and their methods. In C++14, there is a new decltype that is used with the auto keyword, and in the last post pick, we explain how you can use it.

Just visit this site and copy and paste any examples there into a new Console, VCL, or FMX project, depending on the type of post. We keep adding more C and C++ posts with sample code. In today’s round-up of recent posts on LearnCPlusPlus.org, we have new articles with very simple examples that can be used with: The free version of C++ Builder 11 CE Community Edition or a professional version of C++ Builder  or free BCC32C C++ Compiler and BCC32X C++ Compiler or the free Dev-C++ Read the FAQ notes on the CE license and then simply fill out the form to download C++ Builder 11 CE. How to use modern C++ with C++ Builder? In development, sometimes we want to preserve the string format especially when we use a string in a string with /”. In C++14 and above, there is a std::quoted template that allows handling strings safely where they may contain spaces and special characters and it keeps their formatting intact. In the first post, we explain the std::quoted template, and how you can use it with in examples. Containers are powerful data storage arrays in modern C++ and they are very useful to iterate and search data with their amazing methods and properties. The C++ Standards library defines 4 container types. In the next post, we explain containers and types in modern C++. The auto keyword arrives with the new features of C++11 and the standards above. In C++14, there is a new decltype that is used with the auto keyword. […]

This blog post is based on a pre-release version of the RAD Studio software and it has been written with specific permission by Embarcadero. No feature is committed until the product GA release. RAD Studio 12 is just around the corner, and we have exciting news to share! In August, we ran an unusual webinar where we shared a behind-the-scenes look at some technology we’ve been working on for C++Builder and the C++ side of RAD Studio. One of the things we previewed was an upgraded Clang-based Win64 compiler – though not just an upgrade but some major technological improvements to core areas, with a new STL, a new linker, and more. It is a thorough rework of the entire toolchain with a strong eye to making the right decisions for quality and longevity. Table of Contents New Clang Platform standards High performance for the compiled code. Optimised runtimes Excellent language standards compatibility. Excellent quality in all areas, such as exception handling A robust STL. A linker that can handle anything Tech details Status Toolchains in version 12.0 Overall New Clang The C++ compiler is foundational to RAD Studio. Through the Clang & LLVM work, we make LLVM available to Delphi. And, of course, we need a modern, powerful C++ compiler to provide our C++ developers with the best source compatibility, libraries, app performance, and more. Our goals for the work are: Very high quality. A robust STL. A linker that can handle anything and any quantity you give it. Excellent quality in all areas, such as exception handling Excellent language standards compatibility. High performance for the compiled code. Optimised runtimes. Match platform standards as much as possible How are we meeting those? Let’s go in reverse order. Platform standards The new toolchain is based on Clang 15*. The previous toolchain used the ELF object file format, a primarily Unix/Linux format, for historical reasons that are actually (long story) related to Kylix. For this toolchain, we are moving to COFF, which is the standard object file format for Windows compilers of any compiled language. Similarly, we are using the PDB debug format, which again is the standard. While we are not officially supporting any third party tools, there are many tools developers use which understand COFF & PDB and we hope that by adhering to the platform norms, we open up the opportunity to use a wide variety of tools with your apps and C++Builder. [*] Clang 15 was current when this work started, and we are avoiding changing the wheels while the car is in motion. We plan to remain up to date and move forward with Clang itself in future. High performance for the compiled code. While we are aiming for correct compiled code behaviour above all else, we are also aiming for high performance. The new toolchain’s technology generates more optimized code, and allows additional optimisations that were not previously possible in future. Optimised runtimes A C++ toolchain has multiple layers: a C runtime (providing things like printing to a console or file IO), a C++ runtime (providing things like exception handling), and the STL (providing C++ library functions like standard IO, algorithms, collections, etc.) For our toolchain, we are replacing all three.
