Self-relocation
In computer programming, a self-relocating program is a program that relocates its own address-dependent instructions and data when run, and is therefore capable of being loaded into memory at any address. In many cases, self-relocating code is also a form of self-modifying code. Overview Self-relocation is similar to the relocation process employed by the linker-loader when a program is copied from external storage into main memory; the difference is that it is the loaded program itself rather than the loader in the operating system or shell that performs the relocation. One form of self-relocation occurs when a program copies the code of its instructions from one sequence of locations to another sequence of locations within the main memory of a single computer, and then transfers processor control from the instructions found at the source locations of memory to the instructions found at the destination locations of memory. As such, the data operated upon by the algorithm of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Page Boundary Relocation
In software development, relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. A linker (computing), linker usually performs relocation in conjunction with ''symbol resolution'', the process of searching files and libraries to replace symbolic references or names of library (computer science), libraries with actual usable addresses in primary storage, memory before running a program. Relocation is typically done by the linker at link time, but it can also be done at load time by a relocating loader (computing), loader, or at run time (program lifecycle phase), run time by the running program self-relocation, itself. Segmentation Object files are typically segmented into various memory segment or section types. Example segment types include code segment, code segment (.text), data segment, initialized data segment (.data), .bss, uninitialized data segment (.b ...
