Member Function Documentation

◆ getMarkLivePass()

LinkGraphPassFunction llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::getMarkLivePass ( const Triple TT) const
inlineoverridevirtual

Returns the mark-live pass to be used for this link.

If no pass is returned (the default) then the target-specific linker implementation will choose a conservative default (usually marking all symbols live). This function is only called if shouldAddDefaultTargetPasses returns true, otherwise the JITContext is responsible for adding a mark-live pass in modifyPassConfig.

Reimplemented from llvm::jitlink::JITLinkContext.

◆ getMemoryManager()

JITLinkMemoryManager & llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::getMemoryManager ( )
inlineoverridevirtual

Return the MemoryManager to be used for this link.

Implements llvm::jitlink::JITLinkContext.

Definition at line 65 of file LinkGraphLinkingLayer.cpp.

◆ lookup()

void llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::lookup ( const LookupMap Symbols,
std::unique_ptr< JITLinkAsyncLookupContinuation LC 
)
inlineoverridevirtual

◆ modifyPassConfig()

Error llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::modifyPassConfig ( LinkGraph G,
PassConfiguration Config 
)
inlineoverridevirtual

Called by JITLink to modify the pass pipeline prior to linking.

The default version performs no modification.

Reimplemented from llvm::jitlink::JITLinkContext.

Definition at line 232 of file LinkGraphLinkingLayer.cpp.

References Config, G, P, and llvm::Error::success().

◆ notifyEmitted()

Error llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::notifyEmitted ( jitlink::JITLinkMemoryManager::FinalizedAlloc  FA)
inline

◆ notifyFailed()

void llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::notifyFailed ( Error  Err)
inlineoverridevirtual

Notify this context that linking failed.

Called by JITLink if linking cannot be completed.

Implements llvm::jitlink::JITLinkContext.

Definition at line 74 of file LinkGraphLinkingLayer.cpp.

References llvm::orc::LinkGraphLayer::getExecutionSession(), llvm::joinErrors(), P, and llvm::orc::ExecutionSession::reportError().

◆ notifyFinalized()

void llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::notifyFinalized ( JITLinkMemoryManager::FinalizedAlloc  Alloc)
inlineoverridevirtual

Called by JITLink to notify the context that the object has been finalized (i.e.

emitted to memory and memory permissions set). If all of this objects dependencies have also been finalized then the code is ready to run.

Implements llvm::jitlink::JITLinkContext.

◆ notifyMaterializing()

void llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::notifyMaterializing ( LinkGraph G)
inline

References G, and P.

◆ notifyResolved()

Error llvm::orc::LinkGraphLinkingLayer::JITLinkCtx::notifyResolved ( LinkGraph G)
inlineoverridevirtual

Called by JITLink once all defined symbols in the graph have been assigned their final memory locations in the target process.

At this point the LinkGraph can be inspected to build a symbol table, however the block content will not generally have been copied to the target location yet.

If the client detects an error in the LinkGraph state (e.g. unexpected or missing symbols) they may return an error here. The error will be propagated to notifyFailed and the linker will bail out.
