Process Of Software Development : The Waterfall Model

In this semester, we covered three SDLC’s waterfall, incremental, and integration. The waterfall model divided the process of software development into different steps and the next step could not be initialized until the current step was completed. Incremental development was more of an agile development, since the processes could interleave. Integration development relies heavily on reusable code, which focused into integrating the components into the system. GCC and CLANG strive to give users the latest and most recent updates of their compilers. Therefore, with both being updated so frequently, the waterfall model is not the best SDLC for either of these systems. However, GCC or CLANG could be either incremental or integration. Both …show more content…

CLANG allows the public to submit changes that could become requirements, but they need to be validated by the CFE or DEV team depending on what kind of changes need to be made. They also have standards that need to be followed in contemplation of changes becoming requirements.
Software documentation is a key part of the system in order to give guidance of how the architecture of the software project is made. CLANG uses doxygen to generate its documentation, since the system is constantly changing. GCC uses their own online documentation to provide manuals and latest releases. Both GCC and CLANG have incredibly detailed and easy to follow documentation, which gives the user the essential information to perform any task on the compilers.
As described above in brief detail both GCC and CLANG allow the public to submit changes and both have standards that need to be followed in order to get the changes looked at. GCC will only commit changes if is considered a major change. They have a description on what a major change is as well as what the process is to make a major change. CLANG provides a more thorough explanation on what is done to validate a patch and release it to the public, which makes it better in a way. CLANG describes the seven steps that merits a proposed extension, as well as the coding standard that needs to be followed. Both systems have a complex way of validating changes, since they need to guarantee that the change is not only valid but also doesn’t
