◆ classof()

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

For isa/dyn_cast.

Definition at line 1409 of file Constant.h.

References llvm::sandboxir::Value::getSubclassID().

◆ get()

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

◆ 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 437 of file Constant.cpp.

References llvm::cast(), llvm::sandboxir::Constant::Constant(), llvm::sandboxir::Value::Ctx, getAddrDiscriminator(), and llvm::sandboxir::Value::Val.

◆ getDiscriminator()

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

The integer discriminator, an i64 constant, or 0.

Definition at line 432 of file Constant.cpp.

References llvm::cast(), llvm::sandboxir::Constant::ConstantInt, llvm::sandboxir::Value::Ctx, and llvm::sandboxir::Value::Val.

◆ getKey()

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

The Key ID, an i32 constant.

Definition at line 427 of file Constant.cpp.

References llvm::cast(), llvm::sandboxir::Constant::ConstantInt, llvm::sandboxir::Value::Ctx, 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 422 of file Constant.cpp.

References llvm::cast(), llvm::sandboxir::Constant::Constant(), llvm::sandboxir::Value::Ctx, 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 442 of file Constant.cpp.

References llvm::cast(), llvm::sandboxir::Constant::Constant(), llvm::sandboxir::Value::Ctx, 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 1382 of file Constant.h.

References llvm::cast(), and 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 1390 of file Constant.h.

References llvm::cast(), and 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.
