class Function: LLVM/Clang 15.x documentation

This is an important base class in LLVM. It provides the common facilities of all constant values in an LLVM program. A constant is a value that is immutable at runtime. Functions are constants because their address is immutable. Same with global variables. All constants share the capabilities provided in this class.

llvm.org › doxygen › classllvm_1_1Module.html

LLVM: llvm::Module Class Reference

Each module directly contains a list of globals variables, a list of functions, a list of libraries (or other modules) this module depends on, a symbol table, and various data about the target's characteristics. A module maintains a GlobalList object that is used to hold all constant references to global variables in the module. When a global variable is destroyed, it should have no entries in the GlobalList. The main container class for the LLVM Intermediate Representation.

You can create a new function with Function::Create. See this snippet from the LLVM tutorial for example:

Function *PrototypeAST::Codegen() {
  // Make the function type:  double(double,double) etc.
  std::vector<Type*> Doubles(Args.size(),
                             Type::getDoubleTy(getGlobalContext()));
  FunctionType *FT = FunctionType::get(Type::getDoubleTy(getGlobalContext()),
                                       Doubles, false);

  Function *F = Function::Create(FT, Function::ExternalLinkage, Name, TheModule);

LLVM Programmer’s Manual — LLVM 23.0.0git documentation

The handleErrors function takes an error as its first argument, followed by a variadic list of “handlers”, each of which must be a callable type (a function, lambda, or class with a call operator) with one argument. The handleErrors function will visit each handler in the sequence and check its argument type against the dynamic type of the error, running the first handler that matches.

Function Definitions and Declarations — Mapping High Level Constructs to LLVM IR documentation

For LLVM these two are completely different functions, with different names etc. define i32 @_Z8functionii(i32 %a, i32 %b) #0 { ; [...] ret i32 %5 } define double @_Z8functionddd(double %a, double %b, double %x) #0 { ; [...] ret double %8 } Classes or structs are often passed around by value, implicitly cloning the objects when they are passed.
