class JITSymbolResolver
Declaration
class JITSymbolResolver { /* full declaration omitted */ };
Description
Symbol resolution interface. Allows symbol flags and addresses to be looked up by name. Symbol queries are done in bulk (i.e. you request resolution of a set of symbols, rather than a single one) to reduce IPC overhead in the case of remote JITing, and expose opportunities for parallel compilation.

Method Overview
- public virtual bool allowsZeroSymbols()
- private virtual void anchor()
- public virtual Expected<llvm::JITSymbolResolver::LookupSet> getResponsibilitySet(const llvm::JITSymbolResolver::LookupSet & Symbols)
- public virtual void lookup(const llvm::JITSymbolResolver::LookupSet & Symbols, llvm::JITSymbolResolver::OnResolvedFunction OnResolved)
- public virtual ~JITSymbolResolver()
Methods
¶virtual bool allowsZeroSymbols()
virtual bool allowsZeroSymbols()
Description
Specify if this resolver can return valid symbols with zero value.

¶virtual Expected<
llvm::JITSymbolResolver::LookupSet>
getResponsibilitySet(
const llvm::JITSymbolResolver::LookupSet&
Symbols)
virtual Expected<
llvm::JITSymbolResolver::LookupSet>
getResponsibilitySet(
const llvm::JITSymbolResolver::LookupSet&
Symbols)
Description
Returns the subset of the given symbols that should be materialized by the caller. Only weak/common symbols should be looked up, as strong definitions are implicitly always part of the caller's responsibility.
Declared at: llvm/include/llvm/ExecutionEngine/JITSymbol.h:391
Parameters
- const llvm::JITSymbolResolver::LookupSet& Symbols
¶virtual void lookup(
const llvm::JITSymbolResolver::LookupSet&
Symbols,
llvm::JITSymbolResolver::OnResolvedFunction
OnResolved)
virtual void lookup(
const llvm::JITSymbolResolver::LookupSet&
Symbols,
llvm::JITSymbolResolver::OnResolvedFunction
OnResolved)
Description
Returns the fully resolved address and flags for each of the given symbols. This method will return an error if any of the given symbols can not be resolved, or if the resolution process itself triggers an error.
