Caching Compiler (RECC) CppCon 2024 September 19, 2024 Shivam Bairoliya Software Engineer© 2024 Bloomberg Finance L.P. All rights reserved. What is RECC? ● Remote Execution Caching Compiler (RECC) ○ Open source build tool that wraps compiler commands and optionally forwards them to a remote build execution service ○ Encompasses the capabilities of both ccache and distcc ○ Supports remote linking linking and caching ● Designed to share caches across diverse toolchains ○ Works with many compiler toolchains (GCC, Clang, Solaris CC) ○ Supports multiple operating systems (Linux, macOS, Solaris)

create and reuse any number of different binaries (for different config- urations like architectures, compiler versions, etc.) for any number of different versions of a package, using exactly the same process of binaries, one for each different platform and configuration: operating system, architecture, compiler, build type, etc. These binaries can be created and uploaded to a server with the same commands to integrate with any build system, including proprietary ones. Likewise, Conan can manage any compiler and any version. There are default definitions for the most popular ones: gcc, cl.exe, clang, apple-clang

This document serves as the reference for the Pascal language as implemented by the Free Pascal compiler. It describes all Pascal constructs supported by Free Pascal, and lists all supported data types the Pascal language. The Free Pascal compiler emulates these compilers in the appropriate mode of the compiler: certain features are available only if the compiler is switched to the appropriate mode. 1970. It has evolved sig- nificantly since that day, with a lot of contributions by the various compiler constructors (Notably: Borland). The basic elements have been kept throughout the years: • Easy
