◆ createIndirectStubsManager()

std::unique_ptr< IndirectStubsManager > llvm::orc::EPCIndirectionUtils::createIndirectStubsManager ( )

Create an IndirectStubsManager for the executor process.

Definition at line 319 of file EPCIndirectionUtils.cpp.

◆ createLazyCallThroughManager()

LazyCallThroughManager & llvm::orc::EPCIndirectionUtils::createLazyCallThroughManager ( ExecutionSession ES,
ExecutorAddr  ErrorHandlerAddr 
)

Create a LazyCallThroughManager.

This function should only be called once.

◆ CreateWithABI()

template<typename ORCABI >
std::unique_ptr< EPCIndirectionUtils > llvm::orc::EPCIndirectionUtils::CreateWithABI ( ExecutorProcessControl EPC)
static

Create using the given ABI class.

Definition at line 216 of file EPCIndirectionUtils.h.

◆ getABISupport()

ABISupport & llvm::orc::EPCIndirectionUtils::getABISupport ( ) const
inline

Return a reference to the ABISupport object for this instance.

Definition at line 97 of file EPCIndirectionUtils.h.

◆ getExecutorProcessControl()

ExecutorProcessControl & llvm::orc::EPCIndirectionUtils::getExecutorProcessControl ( ) const
inline

Return a reference to the ExecutorProcessControl object.

Definition at line 94 of file EPCIndirectionUtils.h.

◆ getLazyCallThroughManager()

LazyCallThroughManager & llvm::orc::EPCIndirectionUtils::getLazyCallThroughManager ( )
inline

Create a LazyCallThroughManager for the executor process.

Definition at line 126 of file EPCIndirectionUtils.h.

◆ getResolverBlockAddress()

ExecutorAddr llvm::orc::EPCIndirectionUtils::getResolverBlockAddress ( ) const
inline

Returns the address of the Resolver block.

Returns zero if the writeResolverBlock method has not previously been called.

Definition at line 111 of file EPCIndirectionUtils.h.

◆ getTrampolinePool()

TrampolinePool & llvm::orc::EPCIndirectionUtils::getTrampolinePool ( )

Create a TrampolinePool for the executor process.

Definition at line 323 of file EPCIndirectionUtils.cpp.

◆ writeResolverBlock()

Expected< ExecutorAddr > llvm::orc::EPCIndirectionUtils::writeResolverBlock ( ExecutorAddr  ReentryFnAddr,
ExecutorAddr  ReentryCtxAddr 
)

Write resolver code to the executor process and return its address.

This must be called before any call to createTrampolinePool or createLazyCallThroughManager.
