DefineExternalSectionStartAndEndSymbols< SymbolIdentifierFunction > llvm::jitlink::createDefineExternalSectionStartAndEndSymbolsPass | ( | SymbolIdentifierFunction && | F | ) |
Returns a JITLink pass (as a function class) that uses the given symbol identification function to identify external section start and end symbols (and their associated Section*s) and transform the identified externals into defined symbols pointing to the start of the first block in the section and the end of the last (start and end symbols for empty sections will be transformed into absolute symbols at address 0).
The identification function should be callable as
SectionRangeSymbolDesc (LinkGraph &G, Symbol &Sym)
If Sym is not a section range start or end symbol then a default constructed SectionRangeSymbolDesc should be returned. If Sym is a start symbol then SectionRangeSymbolDesc(Sec, true), where Sec is a reference to the target Section. If Sym is an end symbol then SectionRangeSymbolDesc(Sec, false) should be returned.
This pass should be run in the PostAllocationPass pipeline, at which point all blocks should have been assigned their final addresses.

Authors of JITLinkContexts can use this function to register a post-fixup pass that records the range of the eh-frame section. This range can be used after finalization to register and deregister the frame.

jit-link the given LinkGraph.
If PrePrunePasses is empty then a default mark-live pass will be inserted that will mark all exported atoms live. If PrePrunePasses is not empty, the caller is responsible for including a pass to mark atoms as live.
If PostPrunePasses is empty then a default GOT-and-stubs insertion pass will be inserted. If PostPrunePasses is not empty then the caller is responsible for including a pass to insert GOT and stub edges.

void llvm::jitlink::visitExistingEdges | ( | LinkGraph & | G, |
VisitorTs &&... | Vs | ||
) |
For each edge in the given graph, apply a list of visitors to the edge, stopping when the first visitor's visitEdge method returns true.
Only visits edges that were in the graph at call time: if any visitor adds new edges those will not be visited. Visitors are not allowed to remove edges (though they can change their kind, target, and addend).
