◆ classof()

static bool llvm::sandboxir::ConstantPtrAuth::classof ( const sandboxir::Value From)
inlinestatic

For isa/dyn_cast.

Definition at line 1142 of file Constant.h.

References From.

◆ get()

ConstantPtrAuth * llvm::sandboxir::ConstantPtrAuth::get ( Constant Ptr,
ConstantInt Key,
ConstantInt Disc,
Constant AddrDisc 
)
static

Return a pointer signed with the specified parameters.

Definition at line 423 of file Constant.cpp.

References llvm::ConstantPtrAuth::get(), Ptr, and llvm::sandboxir::Value::Val.

◆ getAddrDiscriminator()

Constant * llvm::sandboxir::ConstantPtrAuth::getAddrDiscriminator ( ) const

The address discriminator if any, or the null constant.

If present, this must be a value equivalent to the storage location of the only global-initializer user of the ptrauth signed pointer.

Definition at line 446 of file Constant.cpp.

References llvm::sandboxir::Value::Ctx, getAddrDiscriminator(), llvm::sandboxir::Context::getOrCreateConstant(), and llvm::sandboxir::Value::Val.

Referenced by getAddrDiscriminator().

◆ getDiscriminator()

ConstantInt * llvm::sandboxir::ConstantPtrAuth::getDiscriminator ( ) const

The integer discriminator, an i64 constant, or 0.

Definition at line 441 of file Constant.cpp.

References llvm::sandboxir::Value::Ctx, llvm::sandboxir::Context::getOrCreateConstant(), and llvm::sandboxir::Value::Val.

◆ getKey()

ConstantInt * llvm::sandboxir::ConstantPtrAuth::getKey ( ) const

The Key ID, an i32 constant.

Definition at line 436 of file Constant.cpp.

References llvm::sandboxir::Value::Ctx, llvm::sandboxir::Context::getOrCreateConstant(), and llvm::sandboxir::Value::Val.

◆ getPointer()

Constant * llvm::sandboxir::ConstantPtrAuth::getPointer ( ) const

The pointer that is signed in this ptrauth signed pointer.

Definition at line 431 of file Constant.cpp.

References llvm::sandboxir::Value::Ctx, llvm::sandboxir::Context::getOrCreateConstant(), getPointer(), and llvm::sandboxir::Value::Val.

Referenced by getPointer().

◆ getWithSameSchema()

ConstantPtrAuth * llvm::sandboxir::ConstantPtrAuth::getWithSameSchema ( Constant Pointer) const

Produce a new ptrauth expression signing the given value using the same schema as is stored in one.

Definition at line 451 of file Constant.cpp.

References llvm::sandboxir::Value::Ctx, llvm::sandboxir::Context::getOrCreateConstant(), getWithSameSchema(), and llvm::sandboxir::Value::Val.

Referenced by getWithSameSchema().

◆ hasAddressDiscriminator()

bool llvm::sandboxir::ConstantPtrAuth::hasAddressDiscriminator ( ) const
inline

Whether there is any non-null address discriminator.

Definition at line 1115 of file Constant.h.

References llvm::sandboxir::Value::Val.

◆ hasSpecialAddressDiscriminator()

bool llvm::sandboxir::ConstantPtrAuth::hasSpecialAddressDiscriminator ( uint64_t  Value) const
inline

Whether the address uses a special address discriminator.

These discriminators can't be used in real pointer-auth values; they can only be used in "prototype" values that indicate how some real schema is supposed to be produced.

Definition at line 1123 of file Constant.h.

References llvm::sandboxir::Value::Val.

◆ isKnownCompatibleWith()

bool llvm::sandboxir::ConstantPtrAuth::isKnownCompatibleWith ( const Value Key,
const Value Discriminator,
const DataLayout DL 
) const
inline

Check whether an authentication operation with key Key and (possibly blended) discriminator Discriminator is known to be compatible with this ptrauth signed pointer.

Definition at line 1131 of file Constant.h.
