things we want to find out:
| AsmTempLabel Unique
- | ModuleInitLabel Module
+ | ModuleInitLabel
+ Module -- the module name
+ String -- its "way"
+ -- at some point we might want some kind of version number in
+ -- the module init label, to guard against compiling modules in
+ -- the wrong order. We can't use the interface file version however,
+ -- because we don't always recompile modules which depend on a module
+ -- whose version has changed.
+
+ | PlainModuleInitLabel Module -- without the vesrion & way info
| RtsLabel RtsLabelInfo
- | ForeignLabel FAST_STRING Bool -- a 'C' (or otherwise foreign) label
+ | ForeignLabel FastString Bool -- a 'C' (or otherwise foreign) label
-- Bool <=> is dynamic
| CC_Label CostCentre
data RtsLabelInfo
= RtsShouldNeverHappenCode
- | RtsBlackHoleInfoTbl FAST_STRING -- black hole with info table name
+ | RtsBlackHoleInfoTbl FastString -- black hole with info table name
| RtsUpdInfo -- upd_frame_info
| RtsSeqInfo -- seq_frame_info
| RtsGCEntryLabel String -- a heap check fail handler, eg stg_chk_2
- | RtsMainRegTable -- MainRegTable (??? Capabilities wurble ???)
+ | RtsMainCapability -- MainCapability
| Rts_Closure String -- misc rts closures, eg CHARLIKE_closure
| Rts_Info String -- misc rts itbls, eg MUT_ARR_PTRS_FROZEN_info
| Rts_Code String -- misc rts code
