The simplest way to set the condition flags is to use a comparison operation, such as cmp. This mechanism is common to many processor architectures, and the semantics (if not the details) of cmp will likely be familiar. In addition, we have already seen that many instructions (such as sub in the example) can be modified to … See more Consider a simple fragment of C code: A compiler might implement that structure as follows: The last two instructions are of particular interest. The cmp (compare) instruction compares … See more If you have an Arm platform (or emulator) handy, the attached ccdemoapplication can be used to experiment with the operations discussed in the article.
