Struct melior::dialect::ods::llvm::AddressOfOperation

pub struct AddressOfOperation<'c> { /* private fields */ }

A mlir.addressof operation. Creates a pointer pointing to a global or a function.

Creates an SSA value containing a pointer to a global variable or constant defined by llvm.mlir.global. The global value can be defined after its first referenced. If the global value is a constant, storing into it is not allowed.

Examples:

func @foo() {
  // Get the address of a global variable.
  %0 = llvm.mlir.addressof @const : !llvm.ptr<i32>

  // Use it as a regular pointer.
  %1 = llvm.load %0 : !llvm.ptr<i32>

  // Get the address of a function.
  %2 = llvm.mlir.addressof @foo : !llvm.ptr<func<void ()>>

  // The function address can be used for indirect calls.
  llvm.call %2() : () -> ()
}

// Define the global.
llvm.mlir.global @const(42 : i32) : i32
