class AllocGroup

Declaration

class AllocGroup { /* full declaration omitted */ };

Description

A pair of memory protections and allocation policies. Optimized for use as a small map key.

Methods

¶AllocGroup()

Description

Create a default AllocGroup. No memory protections, standard deallocation policy.

Declared at: llvm/include/llvm/ExecutionEngine/JITLink/MemoryFlags.h:101

¶AllocGroup(llvm::jitlink::MemProt MP)

Description

Create an AllocGroup from a MemProt only -- uses MemoryDeallocationPolicy::Standard.

Declared at: llvm/include/llvm/ExecutionEngine/JITLink/MemoryFlags.h:105

Parameters

llvm::jitlink::MemProt MP

¶AllocGroup(llvm::jitlink::MemProt MP,
           llvm::jitlink::MemDeallocPolicy MDP)

Description

Create an AllocGroup from a MemProt and a MemoryDeallocationPolicy.

Declared at: llvm/include/llvm/ExecutionEngine/JITLink/MemoryFlags.h:108

Parameters

llvm::jitlink::MemProt MP

llvm::jitlink::MemDeallocPolicy MDP

¶AllocGroup(
    llvm::jitlink::AllocGroup::underlying_type
        RawId)

Declared at: llvm/include/llvm/ExecutionEngine/JITLink/MemoryFlags.h:135

Parameters

llvm::jitlink::AllocGroup::underlying_type RawId

¶llvm::jitlink::MemDeallocPolicy
getMemDeallocPolicy() const

Description

Returns the MemoryDeallocationPolicy for this group.

Declared at: llvm/include/llvm/ExecutionEngine/JITLink/MemoryFlags.h:118

¶llvm::jitlink::MemProt getMemProt() const

Description

Returns the MemProt for this group.
