Method Overview

• public static void writeIndirectStubsBlock(char * StubsBlockWorkingMem, llvm::JITTargetAddress StubsBlockTargetAddress, llvm::JITTargetAddress PointersBlockTargetAddress, unsigned int NumStubs)
• public static void writeResolverCode(char * ResolverWorkingMem, llvm::JITTargetAddress ResolverTargetAddress, llvm::JITTargetAddress ReentryFnAddr, llvm::JITTargetAddress ReentryCtxAddr)
• public static void writeTrampolines(char * TrampolineBlockWorkingMem, llvm::JITTargetAddress TrampolineBlockTargetAddress, llvm::JITTargetAddress ResolverFnAddr, unsigned int NumTrampolines)

Methods

¶static void writeIndirectStubsBlock(
    char* StubsBlockWorkingMem,
    llvm::JITTargetAddress
        StubsBlockTargetAddress,
    llvm::JITTargetAddress
        PointersBlockTargetAddress,
    unsigned int NumStubs)

Description

Write NumStubs indirect stubs to working memory at StubsBlockWorkingMem. Stubs will be written as if linked at StubsBlockTargetAddress, with the Nth stub using the Nth pointer in memory starting at PointersBlockTargetAddress.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h:328

Parameters

char* StubsBlockWorkingMem

llvm::JITTargetAddress StubsBlockTargetAddress

llvm::JITTargetAddress PointersBlockTargetAddress

unsigned int NumStubs

¶static void writeResolverCode(
    char* ResolverWorkingMem,
    llvm::JITTargetAddress ResolverTargetAddress,
    llvm::JITTargetAddress ReentryFnAddr,
    llvm::JITTargetAddress ReentryCtxAddr)

Description

Write the resolver code into the given memory. The user is responsible for allocating the memory and setting permissions. ReentryFnAddr should be the address of a function whose signature matches void* (*)(void *TrampolineAddr, void *ReentryCtxAddr). The ReentryCtxAddr argument of writeResolverCode will be passed as the second argument to the function at ReentryFnAddr.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h:312

Parameters

char* ResolverWorkingMem

llvm::JITTargetAddress ResolverTargetAddress

llvm::JITTargetAddress ReentryFnAddr

llvm::JITTargetAddress ReentryCtxAddr

¶static void writeTrampolines(
    char* TrampolineBlockWorkingMem,
    llvm::JITTargetAddress
        TrampolineBlockTargetAddress,
    llvm::JITTargetAddress ResolverFnAddr,
    unsigned int NumTrampolines)

Description

Write the requested number of trampolines into the given memory, which must be big enough to hold 1 pointer, plus NumTrampolines trampolines.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h:320

Parameters

char* TrampolineBlockWorkingMem

llvm::JITTargetAddress TrampolineBlockTargetAddress

llvm::JITTargetAddress ResolverFnAddr

unsigned int NumTrampolines
