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.

Function Documentation

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 76 of file Core.cpp.

References llvm::wrap().

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 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.

char* LLVMGetDiagInfoDescription

(

LLVMDiagnosticInfoRef

DI

)

Return a string representation of the DiagnosticInfo. Use LLVMDisposeMessage to free the string.

See also:

DiagnosticInfo::print()

Definition at line 112 of file Core.cpp.

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

LLVMDiagnosticSeverity LLVMGetDiagInfoSeverity

(

LLVMDiagnosticInfoRef

DI

)

Return an enum LLVMDiagnosticSeverity.

See also:

DiagnosticInfo::getSeverity()

Definition at line 123 of file Core.cpp.

References llvm::DS_Note, llvm::DS_Remark, llvm::DS_Warning, LLVMDSError, LLVMDSNote, LLVMDSRemark, LLVMDSWarning, and llvm::unwrap().

LLVMContextRef LLVMGetGlobalContext

(

void

)

Obtain the global context instance.
