Functions in this group relate to the inspection and manipulation of individual instructions.
In the C++ API, an instruction is modeled by llvm::Instruction. This class has a large number of descendents. llvm::Instruction is a llvm::Value and in the C API, instructions are modeled by LLVMValueRef.
This group also contains sub-groups which operate on specific llvm::Instruction types, e.g. llvm::CallInst.
void LLVMDeleteInstruction | ( | LLVMValueRef | Inst | ) |
Delete an instruction.
The instruction specified is deleted. It must have previously been removed from its containing building block.
LLVMRealPredicate LLVMGetFCmpPredicate | ( | LLVMValueRef | Inst | ) |
Obtain the float predicate of an instruction.
This is only valid for instructions that correspond to llvm::FCmpInst.
LLVMIntPredicate LLVMGetICmpPredicate | ( | LLVMValueRef | Inst | ) |
Obtain the predicate of an instruction.
This is only valid for instructions that correspond to llvm::ICmpInst.
LLVMOpcode LLVMGetInstructionOpcode | ( | LLVMValueRef | Inst | ) |
Obtain the code opcode for an individual instruction.

References llvm::CallingConv::C, map_to_llvmopcode(), and unwrap().
LLVMBasicBlockRef LLVMGetInstructionParent | ( | LLVMValueRef | Inst | ) |
Obtain the basic block to which an instruction belongs.
Definition at line 2881 of file Core.cpp.
References getParent(), and llvm::wrap().
LLVMValueRef LLVMGetMetadata | ( | LLVMValueRef | Val, |
unsigned | KindID | ||
) |
Return metadata associated with an instruction value.
Definition at line 1069 of file Core.cpp.
References assert(), llvm::MetadataAsValue::get(), I, and llvm::wrap().
LLVMValueRef LLVMGetNextInstruction | ( | LLVMValueRef | Inst | ) |
Obtain the instruction that occurs after the one specified.
The next instruction will be from the same basic block.
If this is the last instruction in a basic block, NULL will be returned.
Definition at line 2901 of file Core.cpp.
References I, and llvm::wrap().
LLVMValueRef LLVMGetPreviousInstruction | ( | LLVMValueRef | Inst | ) |
Obtain the instruction that occurred before this one.
If the instruction is the first instruction in a basic block, NULL will be returned.

int LLVMHasMetadata | ( | LLVMValueRef | Val | ) |
LLVMValueRef LLVMInstructionClone | ( | LLVMValueRef | Inst | ) |
Create a copy of 'this' instruction that is identical in all ways except the following:

References llvm::CallingConv::C, unwrap(), and llvm::wrap().
void LLVMInstructionEraseFromParent | ( | LLVMValueRef | Inst | ) |
Remove and delete an instruction.
The instruction specified is removed from its containing building block and then deleted.
LLVMValueMetadataEntry * LLVMInstructionGetAllMetadataOtherThanDebugLoc | ( | LLVMValueRef | Instr, |
size_t * | NumEntries | ||
) |
Returns the metadata associated with an instruction value, but filters out all the debug locations.

References llvm_getMetadata().
void LLVMInstructionRemoveFromParent | ( | LLVMValueRef | Inst | ) |
Remove an instruction.
The instruction specified is removed from its containing building block but is kept alive.
LLVMValueRef LLVMIsATerminatorInst | ( | LLVMValueRef | Inst | ) |
Determine whether an instruction is a terminator.
This routine is named to be compatible with historical functions that did this by querying the underlying C++ type.
