The compiler is not allowed to reorder volatile variable accesses for any reason. And how should you combine volatile and const properly? Be the first to ask a question about Embedded C Coding Standard.
Any reference to the const variable will read from that location. Just a moment while we sign you in to your Goodreads account.
Intelli Sense rated it it was amazing May 31, The volatile keyword, like const, is a type qualifier. Silver rated it it was amazing May 25, standardd Programmers to pitch their skills against a computer. Given this, the processing of exceptional conditions detected inside nested blocks is a potentially valuable application of goto that could be implemented in a manner compliant with the three MISRA-C: The coding standard book details a set of guiding principles as well as specific naming conventions and other rules for the use of data types, functions, preprocessor macros, variables and much more.
Mark Park rated it liked it May 02, Thanks for telling us about the problem. By declaring a variable volatile you are effectively asking the compiler to be as inefficient as possible when it comes to reading or writing that variable.

The name of stzndard public data types shall be prefixed with their module name and an underscore.
Certainly if that forced each of the goto lines to be replaced with more than one line of code, it would have forced programmers to use curly braces. To ensure that developers are able to seamlessly combine stabdard from these important standards, we have updated our standard and verified that all of our rules are in harmony with the most recent version of MISRA C.

It is a preferred practice to avoid all use of the goto keyword. Reading it that way, we can see that the keyword const modifies only the pointer i. Likewise, branching INTO a deeper level of nesting is a universal no-no.
Clarifications and additional code examples have been added to make the rules easier to understand and apply. Another use of const is to mark a hardware register as read-only. Anilkumar Karnati marked it as to-read Feb 24, And none other than Dijkstra 50 years ago now!
