Detailed Description
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.
Function Documentation
◆ LLVMGetFCmpPredicate()
| LLVMRealPredicate LLVMGetFCmpPredicate | ( | LLVMValueRef | Inst | ) |
Obtain the float predicate of an instruction.
This is only valid for instructions that correspond to llvm::FCmpInst or llvm::ConstantExpr whose opcode is llvm::Instruction::FCmp.
- See also
- llvm::FCmpInst::getPredicate()
Definition at line 2637 of file Core.cpp.
References I, and llvm::unwrap().
◆ LLVMGetICmpPredicate()
| LLVMIntPredicate LLVMGetICmpPredicate | ( | LLVMValueRef | Inst | ) |
Obtain the predicate of an instruction.
This is only valid for instructions that correspond to llvm::ICmpInst or llvm::ConstantExpr whose opcode is llvm::Instruction::ICmp.
- See also
- llvm::ICmpInst::getPredicate()
Definition at line 2628 of file Core.cpp.
References I, and llvm::unwrap().
◆ LLVMGetInstructionOpcode()
| LLVMOpcode LLVMGetInstructionOpcode | ( | LLVMValueRef | Inst | ) |
Obtain the code opcode for an individual instruction.
- See also
- llvm::Instruction::getOpCode()
Definition at line 2646 of file Core.cpp.
References C, llvm::Instruction::getOpcode(), map_to_llvmopcode(), and llvm::unwrap().
◆ LLVMGetInstructionParent()
| LLVMBasicBlockRef LLVMGetInstructionParent | ( | LLVMValueRef | Inst | ) |
Obtain the basic block to which an instruction belongs.
- See also
- llvm::Instruction::getParent()
Definition at line 2584 of file Core.cpp.
References getParent(), and llvm::wrap().
◆ LLVMGetMetadata()
| LLVMValueRef LLVMGetMetadata | ( | LLVMValueRef | Val, |
| unsigned | KindID | ||
| ) |
Return metadata associated with an instruction value.
Definition at line 855 of file Core.cpp.
References assert(), llvm::MetadataAsValue::get(), I, and llvm::wrap().
◆ LLVMGetNextInstruction()
| 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 2604 of file Core.cpp.
References llvm::BasicBlock::end(), llvm::Instruction::getParent(), I, and llvm::wrap().
◆ LLVMGetPreviousInstruction()
| 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.
Definition at line 2612 of file Core.cpp.
References llvm::BasicBlock::begin(), llvm::Instruction::getParent(), I, and llvm::wrap().
◆ LLVMHasMetadata()
| int LLVMHasMetadata | ( | LLVMValueRef | Val | ) |
◆ LLVMInstructionClone()
| LLVMValueRef LLVMInstructionClone | ( | LLVMValueRef | Inst | ) |
Create a copy of 'this' instruction that is identical in all ways except the following:
- The instruction has no parent
- The instruction has no name
- See also
- llvm::Instruction::clone()
Definition at line 2652 of file Core.cpp.
References C, llvm::Instruction::clone(), llvm::unwrap(), and llvm::wrap().
◆ LLVMInstructionEraseFromParent()
| void LLVMInstructionEraseFromParent | ( | LLVMValueRef | Inst | ) |
Remove and delete an instruction.
The instruction specified is removed from its containing building block and then deleted.
◆ LLVMInstructionGetAllMetadataOtherThanDebugLoc()
| LLVMValueMetadataEntry* LLVMInstructionGetAllMetadataOtherThanDebugLoc | ( | LLVMValueRef | Instr, |
| size_t * | NumEntries | ||
| ) |
Returns the metadata associated with an instruction value, but filters out all the debug locations.
Definition at line 908 of file Core.cpp.
References llvm_getMetadata().
◆ LLVMInstructionRemoveFromParent()
| void LLVMInstructionRemoveFromParent | ( | LLVMValueRef | Inst | ) |
Remove and delete an instruction.
The instruction specified is removed from its containing building block but is kept alive.
◆ LLVMIsATerminatorInst()
| 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.
Definition at line 2658 of file Core.cpp.
References llvm::dyn_cast(), I, llvm::Instruction::isTerminator(), llvm::unwrap(), and llvm::wrap().
◆ LLVMSetMetadata()
| void LLVMSetMetadata | ( | LLVMValueRef | Val, |
| unsigned | KindID, | ||
| LLVMValueRef | Node | ||
| ) |
Set metadata associated with an instruction value.
Definition at line 877 of file Core.cpp.
