Class Context
Encapsulates an LLVM context
Inherited Members
Namespace: Llvm.NET
Assembly: Llvm.NET.dll
Syntax
public sealed class Context : DisposableObject, IDisposable, IBitcodeModuleFactoryRemarks
A context in LLVM is a container for interning (LLVM refers to this as "uniqueing") various types and values in the system. This allows running multiple LLVM tool transforms etc.. on different threads without causing them to collide namespaces and types even if they use the same name (e.g. module one may have a type Foo, and so does module two but they are completely distinct from each other)
LLVM Debug information is ultimately all parented to a top level DICompileUnit as the scope, and a compilation unit is bound to a BitcodeModule, even though, technically the types are owned by a Context. Thus to keep things simpler and help make working with debug information easier. Llvm.NET encapsulates the native type and the debug type in separate classes that are instances of the IDebugType<TNative, TDebug> interface
note
It is important to be aware of the fact that a Context is not thread safe. The context itself and the object instances it owns are intended for use by a single thread only. Accessing and manipulating LLVM objects from multiple threads may lead to race conditions corrupted state and any number of other undefined issues.
