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 void(* LLVMDiagnosticHandler)(LLVMDiagnosticInfoRef, void *)

Definition at line 473 of file Core.h.

typedef void(* LLVMYieldCallback)(LLVMContextRef, void *)

Definition at line 474 of file Core.h.


Function Documentation

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 76 of file Core.cpp.

References llvm::wrap().

Destroy a context instance.

This should be called for every call to LLVMContextCreate() or memory will be leaked.

Definition at line 99 of file Core.cpp.

References llvm::unwrap().

void LLVMContextSetDiagnosticHandler ( LLVMContextRef  C,
LLVMDiagnosticHandler  Handler,
void *  DiagnosticContext 
)

Set the diagnostic handler for this context.

Definition at line 84 of file Core.cpp.

References LLVM_EXTENSION, and llvm::unwrap().

void LLVMContextSetYieldCallback ( LLVMContextRef  C,
LLVMYieldCallback  Callback,
void *  OpaqueHandle 
)

Set the yield callback function for this context.

LLVMContext::setYieldCallback()

Definition at line 92 of file Core.cpp.

References LLVM_EXTENSION, and llvm::unwrap().

Return a string representation of the DiagnosticInfo.

Use LLVMDisposeMessage to free the string.

DiagnosticInfo::print()

Definition at line 112 of file Core.cpp.

References llvm::raw_ostream::flush(), LLVMCreateMessage(), and llvm::unwrap().

Return an enum LLVMDiagnosticSeverity.
