Lightweight error class with error context and mandatory checking.
static ErrorSuccess success()
Create a success value.
virtual void lookupSymbolsAsync(ArrayRef< LookupRequest > Request, SymbolLookupCompleteFn F)=0
Search for symbols in the target process.
virtual Expected< tpctypes::DylibHandle > loadDylib(const char *DylibPath)=0
Load the dynamic library at the given path and return a handle to it.
static Expected< std::unique_ptr< EPCDynamicLibrarySearchGenerator > > Load(ExecutionSession &ES, const char *LibraryPath, SymbolPredicate Allow=SymbolPredicate(), AddAbsoluteSymbolsFn AddAbsoluteSymbols=nullptr)
Permanently loads the library at the given path and, on success, returns a DynamicLibrarySearchGenera...
Error tryToGenerate(LookupState &LS, LookupKind K, JITDylib &JD, JITDylibLookupFlags JDLookupFlags, const SymbolLookupSet &Symbols) override
DefinitionGenerators should override this method to insert new definitions into the parent JITDylib.
An ExecutionSession represents a running JIT program.
ExecutorProcessControl & getExecutorProcessControl()
Get the ExecutorProcessControl object associated with this ExecutionSession.
DylibManager & getDylibMgr() const
Return the DylibManager for the target process.
Represents a JIT'd dynamic library.
Error define(std::unique_ptr< MaterializationUnitType > &&MU, ResourceTrackerSP RT=nullptr)
Define all symbols provided by the materialization unit to be part of this JITDylib.
Wraps state for a lookup-in-progress.
A set of symbols to look up, each associated with a SymbolLookupFlags value.
SymbolLookupSet & add(SymbolStringPtr Name, SymbolLookupFlags Flags=SymbolLookupFlags::RequiredSymbol)
Add an element to the set.
std::unique_ptr< AbsoluteSymbolsMaterializationUnit > absoluteSymbols(SymbolMap Symbols)
Create an AbsoluteSymbolsMaterializationUnit with the given symbols.
JITDylibLookupFlags
Lookup flags that apply to each dylib in the search order for a lookup.
LookupKind
Describes the kind of lookup being performed.
This is an optimization pass for GlobalISel generic memory operations.
raw_ostream & dbgs()
dbgs() - This returns a reference to a raw_ostream for debugging messages.
A pair of a dylib and a set of symbols to be looked up.
