As we can see, even in the case of a single inheritance, the LLVM IR that is generated can appear…
The basic idea to implement this is to associate a table with function pointers with each object. Here, a table…
A class is a collection of data and methods. A class can inherit from another class, potentially adding more data…
To set multiple attributes, you can use the llvm::AttrBuilder class. The other way to provide additional information is to use…
With the addition of arrays and records to the code generator, you can note that sometimes, the generated code does…
The getelementptr instruction is the workhorse for address calculations. As such, it needs some more explanation. The first operand, [8…
For almost all applications, basic types such as INTEGER are not sufficient. For example, to represent mathematical objects such as…
High-level languages today usually make use of aggregate data types and object-oriented programming (OOP) constructs. LLVM IR has some support…
With all this preparation done, emitting the file boils down to a single function call: PM.run(*M); The ToolOutputFile class automatically…
In LLVM, the IR code is run through a pipeline of passes. Each pass performs a single task, such as…
