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.
Typedef Documentation
◆ LLVMDiagnosticHandler
| typedef void(* LLVMDiagnosticHandler) (LLVMDiagnosticInfoRef, void *) |
◆ 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 79 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 118 of file Core.cpp.
References llvm::unwrap().
◆ LLVMContextGetDiagnosticContext()
| void* LLVMContextGetDiagnosticContext | ( | LLVMContextRef | C | ) |
Get the diagnostic context of this context.
Definition at line 99 of file Core.cpp.
References llvm::unwrap().
◆ LLVMContextGetDiagnosticHandler()
| LLVMDiagnosticHandler LLVMContextGetDiagnosticHandler | ( | LLVMContextRef | C | ) |
Get the diagnostic handler of this context.
Definition at line 94 of file Core.cpp.
References LLVM_EXTENSION, and llvm::unwrap().
◆ LLVMContextSetDiagnosticHandler()
| void LLVMContextSetDiagnosticHandler | ( | LLVMContextRef | C, |
| LLVMDiagnosticHandler | Handler, | ||
| void * | DiagnosticContext | ||
| ) |
Set the diagnostic handler for this context.
Definition at line 85 of file Core.cpp.
References LLVM_EXTENSION, and llvm::unwrap().
◆ 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.
