A software analysis and testing tool suite, that performs static analysis, standards enforcement (eg. MISRA C/C++), dynamic analysis, unit testing and requirements traceability.

Static avoids DLL Hell or more generally dependency hell and therefore can simplify development, distribution and installation. Another trade-off is memory used to load the library. With static linking, a smart linker only includes the code that is actually used, but for a dynamic library, the entire library is loaded into memory.
Examples are templates in C++, and generic programming in Fortran and other languages, in conjunction with function overloading (including operator overloading). Code is said to be monomorphised , with specific data types deduced and traced through the call graph , in order to instantiate specific versions of generic functions , and select ...
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.
C# introduced support for dynamic multimethods in version 4 [8] (April 2010) using the 'dynamic' keyword. The following example demonstrates multimethods. Like many other statically-typed languages, C# also supports static method overloading. [9] Microsoft expects that developers will choose static typing over dynamic typing in most scenarios. [10]
Dynamic linking offers three advantages: Often-used libraries (for example the standard system library) need to be stored in only one location, not duplicated in every single binary. If a library is upgraded or replaced, all programs using it dynamically will immediately benefit from the corrections. Static builds would have to be re-linked first.
Load the element with type native int at index onto the top of the stack as a native int. Object model instruction 0x90 ldelem.i1: Load the element with type int8 at index onto the top of the stack as an int32. Object model instruction 0x92 ldelem.i2: Load the element with type int16 at index onto the top of the stack as an int32.
Call graphs can be dynamic or static. [4] A dynamic call graph is a record of an execution of the program, for example as output by a profiler. Thus, a dynamic call graph can be exact, but only describes one run of the program. A static call graph is a call graph intended to represent every possible run of the program.
