term: software component
text: |
This term is defined by ECSS-E-ST-40C 3.2.28 as a "part of a software
system". For this project a *software component* shall be any of the
following items and nothing else:
* ${softwareunit:/term}
* explicitly defined ${elf:/term} symbol in a
${sourcecode:/term} file
* ${assemblerlanguage:/term} data in a source code file
* ${clanguage:/term} object with static storage duration
* C language object with thread-local storage duration
* ${thread:/term}
* ${interruptservice:/term}
* collection of *software components* (this is a software architecture
element)
Please note that explicitly defined ELF symbols and assembler language
data are considered a software component only if they are defined in a
${sourcecode:/term} file. For example, this rules out symbols
and data generated as side-effects by the toolchain (compiler, assembler,
linker) such as jump tables, linker trampolines, exception frame information,
etc.
