CMake ships with numerous .cmake script files and development tools that facilitate tasks such as finding dependencies (both built-in and external, e.g. FindXYZ modules), testing the toolchain environment and executables, packaging releases (CPack), and managing dependencies on external projects (ExternalProject module).
Ccache is a software development tool that caches compilations so that the next time, the same compilation can be avoided and the results can be taken from the cache. This can greatly speed up recompilation time.
Its small file size (about 100 KB for the x86 TCC executable) and memory footprint allow it to be used directly from a single 1.44 M floppy disk, such as a rescue disk. TCC is intended to produce native x86, x86-64 and ARM code very quickly; according to Bellard, it compiles, assembles and links about nine times faster than GCC does. [ 4 ]
A relatively common and simple toolchain consists of the tools to build for a particular operating system (OS) and CPU architecture; consisting of a compiler, a linker, and a debugger. With a cross-compiler, a toolchain can support cross-platform development. For building more complex software systems, many other tools may be in the toolchain.
False sharing is an inherent artifact of automatically synchronized cache protocols and can also exist in environments such as distributed file systems or databases, but current prevalence is limited to RAM caches.
BitBake recipes specify how a particular package is built. Recipes consist of the source URL (http, https, ftp, cvs, svn, git, local file system) of the package, dependencies and compile or install options. They also store the metadata for the package in standard variables. [4]
int threadLocal; // This is a thread-local variable. shared int global; // This is a global variable shared with all threads. The shared keyword works both as the storage class, and as a type qualifier – shared variables are subject to some restrictions which statically enforce data integrity. [ 13 ]
Cache prefetching can be accomplished either by hardware or by software. [3]Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being requested by the executing program, recognizes the next few elements that the program might need based on this stream and prefetches into the processor's ...
