Function Documentation

Obtain the number of operands from an MDNode value.

Parameters:
VMDNode to get number of operands from.
Returns:
Number of operands of the MDNode.

Definition at line 680 of file Core.cpp.

References llvm::unwrap().

Obtain the given MDNode's operands.

The passed LLVMValueRef pointer should point to enough memory to hold all of the operands of the given MDNode (see LLVMGetMDNodeNumOperands) as LLVMValueRefs. This memory will be populated with the LLVMValueRefs of the MDNode's operands.

Parameters:
VMDNode to get the operands from.
DestDestination array for operands.

Definition at line 685 of file Core.cpp.

const char* LLVMGetMDString ( LLVMValueRef  V,
unsigned Len 
)

Obtain the underlying string from a MDString value.

Parameters:
VInstance to obtain string from.
LenMemory address which will hold length of returned string.
Returns:
String data in MDString.

Definition at line 671 of file Core.cpp.

References llvm::unwrap().

LLVMValueRef LLVMMDNode ( LLVMValueRef Vals,
unsigned  Count 
)

Obtain a MDNode value from the global context.

Definition at line 667 of file Core.cpp.

References LLVMGetGlobalContext(), and LLVMMDNodeInContext().

Obtain a MDNode value from a context.

The returned value corresponds to the llvm::MDNode class.

LLVMValueRef LLVMMDString ( const char *  Str,
unsigned  SLen 
)

Obtain a MDString value from the global context.

Definition at line 657 of file Core.cpp.

References LLVMGetGlobalContext(), and LLVMMDStringInContext().

Obtain a MDString value from a context.

The returned instance corresponds to the llvm::MDString class.

The instance is specified by string data of a specified length. The string content is copied, so the backing memory can be freed after this function returns.
