Extract arithmetic operation information from C++ code



I am facing a problem of extracting arithmetic operation information from C++ source code. For example, I want to parse a C++ code such that I can find out the the line numbers for all the codes that conduct arithmetic operations as well as the name of the variables or literals involved in the operation and the corresponding operation type. I am interested in built-in types such as int and double as well as user-defined classes where arithmetic operators such as operator+, operator* are overloaded.



Any idea how this can be achieved?



Edit: I was hoping that some compilers might generate some intermediate results that I can utilize to achieve this goal. I did some search and it seems that libclang can generate some useful intermediate results, but I just want to get some suggestions before I spend too much time on digging into it.





So you want to account for all arithmetic operation in the source code as written, regardless of whether such operations may be eliminated or modified in generated machine code during code optimizations, e.g. through CSE or strength reduction?

Are you really trying to parse h and cpp files yourself?? You should start reading Dragon's (Aho et al. ) book.

h and cpp





The only way to parse C++ code is by using a C++ compiler. C++ is the most complicated general-purpose programming language in use today, and the only kind of a program in the world that knows how to parse C++ code is a C++ compiler. Looks like what you need to do is write your own C++ compiler, which should only take a few years. Just a few.

@njuffa yes I want to extract the information before optimization.

Clash Royale CLAN TAG #URR8PPP Store custom data using WC_Cart add_to_cart() method in Woocommerce 3 I am creating a membership site and totally created static pages for each Membership plans (have only 3 plans). However, I have added products for each plan and when I hit SELECT PLAN button I redirect to some custom form where I ask users range of info we are going to use to fulfil the plan (same as sneakertub.com). I have written code into the PHP page which will handle SUBMIT action of the form. This PHP file, infopage.php , will process POST data I sent via POST call and stores these all data into WC session. infopage.php $customer_name = $_POST["customer_name"]; $customer_email = $_POST["customer_email"]; $customer_sex = $_POST["customer_sex"]; $customer_age = $_POST["customer_age"]; $product_id = $_POST["product_id"]; global $wp_session; $data = array( 'customer_name' => $customer_name, 'customer_email' =...

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...
