Detailed Description
Contexts are execution states for the core LLVM IR system.
Most types are tied to a context instance. Multiple contexts can exist simultaneously. A single context is not thread safe. However, different contexts can execute on different threads simultaneously.

◆ LLVMYieldCallback
| typedef void(* LLVMYieldCallback) (LLVMContextRef, void *) |
Function Documentation
◆ LLVMContextCreate()
| LLVMContextRef LLVMContextCreate | ( | void | ) |
Create a new context.
Every call to this function should be paired with a call to LLVMContextDispose() or the context will leak memory.
Definition at line 97 of file Core.cpp.
References llvm::wrap().
◆ LLVMContextDispose()
| void LLVMContextDispose | ( | LLVMContextRef | C | ) |
Destroy a context instance.
This should be called for every call to LLVMContextCreate() or memory will be leaked.
Definition at line 136 of file Core.cpp.
References llvm::CallingConv::C, and unwrap().
◆ LLVMContextGetDiagnosticContext()
| void * LLVMContextGetDiagnosticContext | ( | LLVMContextRef | C | ) |
Get the diagnostic context of this context.
Definition at line 117 of file Core.cpp.
References llvm::CallingConv::C, and unwrap().
◆ LLVMContextGetDiagnosticHandler()
| LLVMDiagnosticHandler LLVMContextGetDiagnosticHandler | ( | LLVMContextRef | C | ) |
Get the diagnostic handler of this context.

◆ LLVMContextSetDiagnosticHandler()
| void LLVMContextSetDiagnosticHandler | ( | LLVMContextRef | C, |
| LLVMDiagnosticHandler | Handler, | ||
| void * | DiagnosticContext | ||
| ) |
Set the diagnostic handler for this context.

◆ LLVMContextSetDiscardValueNames()
| void LLVMContextSetDiscardValueNames | ( | LLVMContextRef | C, |
| LLVMBool | Discard | ||
| ) |
Set whether the given context discards all value names.
If true, only the names of GlobalValue objects will be available in the IR. This can be used to save memory and runtime, especially in release mode.
