In Objective-C, a trampoline is an object returned by a method that captures and reifies all messages sent to it and then "bounces" those messages on to another object, for example in higher order messaging. [6] In the GCC compiler, trampoline refers to a technique for implementing pointers to nested functions when -ftrampolines option is ...
In Java, the signature of a method or a class contains its name and the types of its method arguments and return value, where applicable. The format of signatures is documented, as the language, compiler, and .class file format were all designed together (and had object-orientation and universal interoperability in mind from the start).
Weak symbols can be used as a mechanism to provide default implementations of functions that can be replaced by more specialized (e.g. optimized) ones at link-time. The default implementation is then declared as weak, and, on certain targets, object files with strongly declared symbols are added to the linker command line.
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
[citation needed] The file is generated alongside the object file during source compilation. Each source compilation generates a separate object file and link-time helper file. When the object files are linked, the compiler is executed again and uses the helper files to optimize code across the separately compiled object files. Plugins
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
While version 2.1 of the LGPL was a standalone licence, the current LGPL version 3 is based on a reference to the GPL.. Compared to the GNU Classpath license above, the LGPL formulates more requirements to the linking exception: licensees must allow modification of the portions of the library they use and reverse engineering (of their software and the library) for debugging such modifications.
crt0 (also known as c0) is a set of execution startup routines linked into a C program that performs any initialization work required before calling the program's main function. After the main function completes the control returns to crt0, which calls the library function exit(0) to terminate the process.
