#define LLVM_ATTRIBUTE_RETURNS_NONNULL
This file defines counterparts of C library allocation functions defined in the namespace 'std'.
CRTP base class providing obvious overloads for the core Allocate() methods of LLVM-style allocators.
void * Allocate(size_t Size, size_t Alignment)
Allocate Size bytes of Alignment aligned memory.
T * Allocate(size_t Num=1)
Allocate space for a sequence of objects without constructing them.
void Deallocate(const void *Ptr, size_t Size, size_t Alignment)
Deallocate Ptr to Size bytes of memory allocated by this allocator.
std::enable_if_t<!std::is_same_v< std::remove_cv_t< T >, void >, void > Deallocate(T *Ptr, size_t Num=1)
Deallocate space for a sequence of objects without constructing them.

This is an optimization pass for GlobalISel generic memory operations.
LLVM_ATTRIBUTE_RETURNS_NONNULL LLVM_ATTRIBUTE_RETURNS_NOALIAS void * allocate_buffer(size_t Size, size_t Alignment)
Allocate a buffer of memory with the given size and alignment.
void deallocate_buffer(void *Ptr, size_t Size, size_t Alignment)
Deallocate a buffer of memory with the given size and alignment.
