◆ APFloat

using clang::interp::APFloat = typedef llvm::APFloat

Definition at line 23 of file Floating.h.

◆ APInt

typedef llvm::APInt clang::interp::APInt

Definition at line 29 of file Integral.h.

◆ APSInt

typedef llvm::APSInt clang::interp::APSInt

Definition at line 24 of file Floating.h.

◆ BlockCtorFn

using clang::interp::BlockCtorFn = typedef void (*)(Block *Storage, std::byte *FieldPtr, bool IsConst, bool IsMutable, bool IsActive, const Descriptor *FieldDesc)

Invoked whenever a block is created.

The constructor method fills in the inline descriptors of all fields and array elements. It also initializes all the fields which contain non-trivial types.

Definition at line 31 of file Descriptor.h.

◆ BlockDtorFn

using clang::interp::BlockDtorFn = typedef void (*)(Block *Storage, std::byte *FieldPtr, const Descriptor *FieldDesc)

Invoked when a block is destroyed.

Invokes the destructors of all non-trivial nested fields of arrays and records.

Definition at line 37 of file Descriptor.h.

◆ BlockMoveFn

using clang::interp::BlockMoveFn = typedef void (*)(Block *Storage, const std::byte *SrcFieldPtr, std::byte *DstFieldPtr, const Descriptor *FieldDesc)

Invoked when a block with pointers referencing it goes out of scope.

Such blocks are persisted: the move function copies all inline descriptors and non-trivial fields, as existing pointers might need to reference those descriptors. Data is not copied since it cannot be legally read.

Definition at line 44 of file Descriptor.h.
