Because the expression 0 will always evaluate to false, the code inside the if statement can never be executed, and dead-code elimination would remove it entirely from the optimized program. This technique is common in debugging to optionally activate blocks of code; using an optimizer with dead-code elimination eliminates the need for using a ...
The term dead code has multiple definitions. Some use the term to refer to code (i.e. instructions in memory) which can never be executed at run-time. [1] [2] [3] In some areas of computer programming, dead code is a section in the source code of a program which is executed but whose result is never used in any other computation.
Of the many apps you likely have on your iPhone or iPad right now, how many do you actually use regularly? Chances are that you have at least a few that you're keeping merely because they have ...
If the undeletion program cannot detect clear signs of the above requirements not being met, it will restore the directory entry as being in use and mark all consecutive clusters, beginning with the one as recorded in the old directory entry, as used in the File Allocation Table. It is then up to the user to open the recovered file and to ...
[3] Tom's Hardware rated it 4.5/5 stars and wrote, "This program manages to do a good job of making sure that your computer is free from bloatware and programs that you don't need." [ 4 ] Ian Paul of PC World called it "easy and straight-forward", but called the program's reliance on accessing Reason Software's website annoying. [ 5 ]
An uninstaller, also called a deinstaller, is a variety of utility software designed to remove other software or parts of it from a computer. It is the opposite of an installer . Uninstallers are useful primarily when software components are installed in multiple directories, or where some software components might be shared between the system ...
Code reuse is the practice of using existing source code to develop software instead of writing new code. Software reuse is a broader term that implies using any existing software asset to develop software instead of developing it again. [1] [2]: 7 An asset that is relatively easy to reuse and offers significant value is considered highly ...
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses.Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.
