In computing, copy-and-patch compilation is a simple compiler technique intended for just-in-time compilation (JIT compilation) that uses pattern matching to match pre-generated templates to parts of an abstract syntax tree (AST) or bytecode stream, and emit corresponding pre-written machine code fragments that are then patched to insert memory addresses, register addresses, constants and ...
Using the PUT method consumes more bandwidth as compared to the PATCH method when only a few changes need to be applied to a resource. [citation needed] But when the PATCH method is used, it usually involves fetching the resource from the server, comparing the original and new files, creating and sending a diff file. On the server side, the ...
This process is called fuzzy patch application, and results in a kind of asymmetric three-way merge, where the changes in the patch are discarded if the patch program cannot find a place in which to apply them. Like CVS started as a set of scripts on diff3, GNU arch started as a set of scripts on patch. However, fuzzy patch application is a ...
A patch is data that is intended to be used to modify an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. [1] [2] A patch may be created to improve functionality, usability, or performance. A patch is typically provided by a vendor for updating the software that they provide.
The Watcom C/C++ compiler also uses the #pragma aux [20] directive that allows the user to specify their own calling convention. As its manual states, "Very few users are likely to need this method, but if it is needed, it can be a lifesaver".

C compilers do not name mangle symbols in the way that C++ compilers do. [20] Depending on the compiler and architecture, it also may be the case that calling conventions differ between the two languages. For these reasons, for C++ code to call a C function foo(), the C++ code must prototype foo() with extern "C".
