Exact lookup

1. lookupFirstUsed :: VirtualReg -> BlockAssignment freeRegs -> Maybe RealReg

   ghc-lib	GHC.CmmToAsm.Reg.Linear.Base

   Lookup which register a virtual register was first assigned to.

2. lookupRegUse :: GlobalReg -> [GlobalRegUse] -> Maybe GlobalRegUse

   ghc-lib	GHC.CmmToLlvm.Base

   No documentation available.

3. lookupNode :: Uniquable k => Graph k cls color -> k -> Maybe (Node k cls color)

   ghc-lib	GHC.Data.Graph.Ops

   Lookup a node from the graph.

4. lookupEstimatedTicks :: HscEnv -> Map CmmInfoTable (Maybe IpeSourceLocation) -> IPEStats -> CmmGroupSRTs -> IO (Map CmmInfoTable (Maybe IpeSourceLocation), IPEStats)

   ghc-lib	GHC.Driver.GenerateCgIPEStub

   Given: * an initial mapping from info tables to possible source locations, * initial IPEStats, * a CmmGroupSRTs, map every info table listed in the CmmProcs of the group to their possible source locations and update IPEStats for skipped stack info tables (in case both -finfo-table-map and -fno-info-table-map-with-stack were given). See: Note [Stacktraces from Info Table Provenance Entries (IPE based stack unwinding)] Note: While it would be cleaner if we could keep the recursion and accumulation internal to this function, this cannot be done without separately traversing stream of CmmGroupSRTs in Main. The initial implementation of this logic did such a thing, and code generation performance suffered considerably as a result (see #23103).

5. lookupIfaceTop :: OccName -> IfL Name

   ghc-lib	GHC.Iface.Env

   Look up a top-level name from the current Iface module

6. lookupIfaceTyVar :: IfaceTvBndr -> IfL (Maybe TyVar)

   ghc-lib	GHC.Iface.Env

   No documentation available.

7. lookupIfaceVar :: IfaceBndr -> IfL (Maybe TyCoVar)

   ghc-lib	GHC.Iface.Env

   No documentation available.

8. lookupNameCache :: NameCache -> Module -> OccName -> IO Name

   ghc-lib	GHC.Iface.Env

   No documentation available.

9. lookupOrig :: Module -> OccName -> TcRnIf a b Name

   ghc-lib	GHC.Iface.Env

   Look up the Name for a given Module and OccName. Consider alternatively using lookupIfaceTop if you're in the IfL monad and Module is simply that of the ModIface you are typechecking.

10. lookupOrigNameCache :: OrigNameCache -> Module -> OccName -> Maybe Name

    ghc-lib	GHC.Iface.Env

    No documentation available.
