+/*
+ * This is the master file that defines all the data structure, signature,
+ * constant literals that are shared across profiling runtime library,
+ * compiler (instrumentation), and host tools (reader/writer). The entities
+ * defined in this file affect the profile runtime ABI, the raw profile format,
+ * or both.
+ *
+ * The file has two identical copies. The master copy lives in LLVM and
+ * the other one sits in compiler-rt/lib/profile directory. To make changes
+ * in this file, first modify the master copy and copy it over to compiler-rt.
+ * Testing of any change in this file can start only after the two copies are
+ * synced up.
+ *
+ * The first part of the file includes macros that defines types, names, and
+ * initializers for the member fields of the core data structures. The field
+ * declarations for one structure is enabled by defining the field activation
+ * macro associated with that structure. Only one field activation record
+ * can be defined at one time and the rest definitions will be filtered out by
+ * the preprocessor.
+ *
+ * Examples of how the template is used to instantiate structure definition:
+ * 1. To declare a structure:
+ *
+ * struct ProfData {
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * Type Name;
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ * 2. To construct LLVM type arrays for the struct type:
+ *
+ * Type *DataTypes[] = {
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * LLVMType,
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ * 4. To construct constant array for the initializers:
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * Initializer,
+ * Constant *ConstantVals[] = {
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ *
+ * The second part of the file includes definitions all other entities that
+ * are related to runtime ABI and format. When no field activation macro is
+ * defined, this file can be included to introduce the definitions.

+HANDLE_TARGET_OPCODE(PHI)
+HANDLE_TARGET_OPCODE(INLINEASM)
+HANDLE_TARGET_OPCODE(CFI_INSTRUCTION)
+HANDLE_TARGET_OPCODE(EH_LABEL)
+HANDLE_TARGET_OPCODE(GC_LABEL)
+
+/// KILL - This instruction is a noop that is used only to adjust the
+/// liveness of registers. This can be useful when dealing with
+/// sub-registers.
+HANDLE_TARGET_OPCODE(KILL)
+
+/// EXTRACT_SUBREG - This instruction takes two operands: a register
+/// that has subregisters, and a subregister index. It returns the
+/// extracted subregister value. This is commonly used to implement
+/// truncation operations on target architectures which support it.
+HANDLE_TARGET_OPCODE(EXTRACT_SUBREG)
+
+/// INSERT_SUBREG - This instruction takes three operands: a register that
+/// has subregisters, a register providing an insert value, and a
+/// subregister index. It returns the value of the first register with the
+/// value of the second register inserted. The first register is often
+/// defined by an IMPLICIT_DEF, because it is commonly used to implement
+/// anyext operations on target architectures which support it.
+HANDLE_TARGET_OPCODE(INSERT_SUBREG)
+
+/// IMPLICIT_DEF - This is the MachineInstr-level equivalent of undef.
+HANDLE_TARGET_OPCODE(IMPLICIT_DEF)
+
+/// SUBREG_TO_REG - Assert the value of bits in a super register.
+/// The result of this instruction is the value of the second operand inserted
+/// into the subregister specified by the third operand. All other bits are
+/// assumed to be equal to the bits in the immediate integer constant in the
+/// first operand. This instruction just communicates information; No code
+/// should be generated.
+/// This is typically used after an instruction where the write to a subregister
+/// implicitly cleared the bits in the super registers.
+HANDLE_TARGET_OPCODE(SUBREG_TO_REG)
+
+/// COPY_TO_REGCLASS - This instruction is a placeholder for a plain
+/// register-to-register copy into a specific register class. This is only
+/// used between instruction selection and MachineInstr creation, before
+/// virtual registers have been created for all the instructions, and it's
+/// only needed in cases where the register classes implied by the
+/// instructions are insufficient. It is emitted as a COPY MachineInstr.
+ HANDLE_TARGET_OPCODE(COPY_TO_REGCLASS)
+
+/// DBG_VALUE - a mapping of the llvm.dbg.value intrinsic
+HANDLE_TARGET_OPCODE(DBG_VALUE)
+
+/// REG_SEQUENCE - This variadic instruction is used to form a register that
+/// represents a consecutive sequence of sub-registers. It's used as a
+/// register coalescing / allocation aid and must be eliminated before code
+/// emission.
+// In SDNode form, the first operand encodes the register class created by
+// the REG_SEQUENCE, while each subsequent pair names a vreg + subreg index
+// pair. Once it has been lowered to a MachineInstr, the regclass operand
+// is no longer present.
+/// e.g. v1027 = REG_SEQUENCE v1024, 3, v1025, 4, v1026, 5
+/// After register coalescing references of v1024 should be replace with
+/// v1027:3, v1025 with v1027:4, etc.
+ HANDLE_TARGET_OPCODE(REG_SEQUENCE)
+
+/// COPY - Target-independent register copy. This instruction can also be
+/// used to copy between subregisters of virtual registers.
+ HANDLE_TARGET_OPCODE(COPY)
+
+/// BUNDLE - This instruction represents an instruction bundle. Instructions
+/// which immediately follow a BUNDLE instruction which are marked with
+/// 'InsideBundle' flag are inside the bundle.
+HANDLE_TARGET_OPCODE(BUNDLE)
+
+/// Lifetime markers.
+HANDLE_TARGET_OPCODE(LIFETIME_START)
+HANDLE_TARGET_OPCODE(LIFETIME_END)
+
+/// A Stackmap instruction captures the location of live variables at its
+/// position in the instruction stream. It is followed by a shadow of bytes
+/// that must lie within the function and not contain another stackmap.
+HANDLE_TARGET_OPCODE(STACKMAP)
+
+/// Patchable call instruction - this instruction represents a call to a
+/// constant address, followed by a series of NOPs. It is intended to
+/// support optimizations for dynamic languages (such as javascript) that
+/// rewrite calls to runtimes with more efficient code sequences.
+/// This also implies a stack map.
+HANDLE_TARGET_OPCODE(PATCHPOINT)
+
+/// This pseudo-instruction loads the stack guard value. Targets which need
+/// to prevent the stack guard value or address from being spilled to the
+/// stack should override TargetLowering::emitLoadStackGuardNode and
+/// additionally expand this pseudo after register allocation.
+HANDLE_TARGET_OPCODE(LOAD_STACK_GUARD)
+
+/// Call instruction with associated vm state for deoptimization and list
+/// of live pointers for relocation by the garbage collector. It is
+/// intended to support garbage collection with fully precise relocating
+/// collectors and deoptimizations in either the callee or caller.
+HANDLE_TARGET_OPCODE(STATEPOINT)
+
+/// Instruction that records the offset of a local stack allocation passed to
+/// llvm.localescape. It has two arguments: the symbol for the label and the
+/// frame index of the local stack allocation.
+HANDLE_TARGET_OPCODE(LOCAL_ESCAPE)
+
+/// Loading instruction that may page fault, bundled with associated
+/// information on how to handle such a page fault. It is intended to support
+/// "zero cost" null checks in managed languages by allowing LLVM to fold
+/// comparisons into existing memory operations.
+HANDLE_TARGET_OPCODE(FAULTING_LOAD_OP)
+
+/// Wraps a machine instruction to add patchability constraints. An
+/// instruction wrapped in PATCHABLE_OP has to either have a minimum
+/// size or be preceded with a nop of that size. The first operand is
+/// an immediate denoting the minimum size of the instruction, the
+/// second operand is an immediate denoting the opcode of the original
+/// instruction. The rest of the operands are the operands of the
+/// original instruction.
+HANDLE_TARGET_OPCODE(PATCHABLE_OP)
+
+/// This is a marker instruction which gets translated into a nop sled, useful
+/// for inserting instrumentation instructions at runtime.
+HANDLE_TARGET_OPCODE(PATCHABLE_FUNCTION_ENTER)
+
+/// Wraps a return instruction and its operands to enable adding nop sleds
+/// either before or after the return. The nop sleds are useful for inserting
+/// instrumentation instructions at runtime.
+/// The patch here replaces the return instruction.
+HANDLE_TARGET_OPCODE(PATCHABLE_RET)
+
+/// This is a marker instruction which gets translated into a nop sled, useful
+/// for inserting instrumentation instructions at runtime.
+/// The patch here prepends the return instruction.
+/// The same thing as in x86_64 is not possible for ARM because it has multiple
+/// return instructions. Furthermore, CPU allows parametrized and even
+/// conditional return instructions. In the current ARM implementation we are
+/// making use of the fact that currently LLVM doesn't seem to generate
+/// conditional return instructions.
+/// On ARM, the same instruction can be used for popping multiple registers
+/// from the stack and returning (it just pops pc register too), and LLVM
+/// generates it sometimes. So we can't insert the sled between this stack
+/// adjustment and the return without splitting the original instruction into 2
+/// instructions. So on ARM, rather than jumping into the exit trampoline, we
+/// call it, it does the tracing, preserves the stack and returns.
+HANDLE_TARGET_OPCODE(PATCHABLE_FUNCTION_EXIT)
+
+/// Wraps a tail call instruction and its operands to enable adding nop sleds
+/// either before or after the tail exit. We use this as a disambiguation from
+/// PATCHABLE_RET which specifically only works for return instructions.
+HANDLE_TARGET_OPCODE(PATCHABLE_TAIL_CALL)

+/// This is something we might want to relax, but for now, this is convenient

+// needed to adapt it to (for example) the Intel 80-bit format or PowerPC
+// double-double format.
+//
+// Note please, however, that this implementation is only intended to support
+// *narrowing* operations; if you need to convert to a *wider* floating-point
+// type (e.g. float -> double), then this routine will not do what you want it
+// to.
+//
+// It also requires that integer types at least as large as both formats
+// are available on the target platform; this may pose a problem when trying

+/*
+ * This is the master file that defines all the data structure, signature,
+ * constant literals that are shared across profiling runtime library,
+ * compiler (instrumentation), and host tools (reader/writer). The entities
+ * defined in this file affect the profile runtime ABI, the raw profile format,
+ * or both.
+ *
+ * The file has two identical copies. The master copy lives in LLVM and
+ * the other one sits in compiler-rt/lib/profile directory. To make changes
+ * in this file, first modify the master copy and copy it over to compiler-rt.
+ * Testing of any change in this file can start only after the two copies are
+ * synced up.
+ *
+ * The first part of the file includes macros that defines types, names, and
+ * initializers for the member fields of the core data structures. The field
+ * declarations for one structure is enabled by defining the field activation
+ * macro associated with that structure. Only one field activation record
+ * can be defined at one time and the rest definitions will be filtered out by
+ * the preprocessor.
+ *
+ * Examples of how the template is used to instantiate structure definition:
+ * 1. To declare a structure:
+ *
+ * struct ProfData {
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * Type Name;
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ * 2. To construct LLVM type arrays for the struct type:
+ *
+ * Type *DataTypes[] = {
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * LLVMType,
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ * 4. To construct constant array for the initializers:
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * Initializer,
+ * Constant *ConstantVals[] = {
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ *
+ * The second part of the file includes definitions all other entities that
+ * are related to runtime ABI and format. When no field activation macro is
+ * defined, this file can be included to introduce the definitions.

+
+/// CK_Dependent - A conversion which cannot yet be analyzed because
+/// either the expression or target type is dependent. These are
+/// created only for explicit casts; dependent ASTs aren't required
+/// to even approximately type-check.
+/// (T*) malloc(sizeof(T))
+/// reinterpret_cast<intptr_t>(A<T>::alloc());
+CAST_OPERATION(Dependent)
+
+/// CK_BitCast - A conversion which causes a bit pattern of one type
+/// to be reinterpreted as a bit pattern of another type. Generally
+/// the operands must have equivalent size and unrelated types.
+///
+/// The pointer conversion char* -> int* is a bitcast. A conversion
+/// from any pointer type to a C pointer type is a bitcast unless
+/// it's actually BaseToDerived or DerivedToBase. A conversion to a
+/// block pointer or ObjC pointer type is a bitcast only if the
+/// operand has the same type kind; otherwise, it's one of the
+/// specialized casts below.
+///
+/// Vector coercions are bitcasts.
+CAST_OPERATION(BitCast)
+
+/// CK_LValueBitCast - A conversion which reinterprets the address of
+/// an l-value as an l-value of a different kind. Used for
+/// reinterpret_casts of l-value expressions to reference types.
+/// bool b; reinterpret_cast<char&>(b) = 'a';
+CAST_OPERATION(LValueBitCast)
+
+/// CK_LValueToRValue - A conversion which causes the extraction of
+/// an r-value from the operand gl-value. The result of an r-value
+/// conversion is always unqualified.
+CAST_OPERATION(LValueToRValue)
+
+/// CK_NoOp - A conversion which does not affect the type other than
+/// (possibly) adding qualifiers.
+/// int -> int
+/// char** -> const char * const *
+CAST_OPERATION(NoOp)
+
+/// CK_BaseToDerived - A conversion from a C++ class pointer/reference
+/// to a derived class pointer/reference.
+/// B *b = static_cast<B*>(a);
+CAST_OPERATION(BaseToDerived)
+
+/// CK_DerivedToBase - A conversion from a C++ class pointer
+/// to a base class pointer.
+/// A *a = new B();
+CAST_OPERATION(DerivedToBase)
+
+/// CK_UncheckedDerivedToBase - A conversion from a C++ class
+/// pointer/reference to a base class that can assume that the
+/// derived pointer is not null.

+/// b->method_from_a();
+CAST_OPERATION(UncheckedDerivedToBase)
+
+/// CK_Dynamic - A C++ dynamic_cast.

+/// CK_ToUnion - The GCC cast-to-union extension.
+/// int -> union { int x; float y; }
+/// float -> union { int x; float y; }
+CAST_OPERATION(ToUnion)

+/// pointer, or block pointer.
+/// (void*) 0
+/// void (^block)() = 0;

+/// member pointer in base class.
+/// int A::*mptr = static_cast<int A::*>(&B::member);
+CAST_OPERATION(DerivedToBaseMemberPointer)
+
+/// CK_MemberPointerToBoolean - Member pointer to boolean. A check
+/// against the null member pointer.
+CAST_OPERATION(MemberPointerToBoolean)
+
+/// CK_ReinterpretMemberPointer - Reinterpret a member pointer as a
+/// different kind of member pointer. C++ forbids this from
+/// crossing between function and object types, but otherwise does
+/// not restrict it. However, the only operation that is permitted
+/// on a "punned" member pointer is casting it back to the original
+/// type, which is required to be a lossless operation (although
+/// many ABIs do not guarantee this on all possible intermediate types).
+CAST_OPERATION(ReinterpretMemberPointer)

+/// CK_UserDefinedConversion - Conversion using a user defined type
+/// conversion function.

+/// __attribute__((ext_vector_type(4))) int v = 5;
+CAST_OPERATION(VectorSplat)
