This file defines the BumpPtrAllocator interface.
This file defines the SmallVector class.
ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...
Definition: ArrayRef.h:41
Allocate memory in an ever growing pool, as if by bump-pointer.
Definition: Allocator.h:66
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.
Definition: SmallVector.h:1210
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50

ArrayRef< ArrayRef< uint8_t > > records() const
ArrayRef< uint8_t > serialize(T &Record)
A 32-bit type reference.
Definition: TypeIndex.h:96
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
StringRef getTypeName()
We provide a function which tries to compute the (demangled) name of a type statically.
