History
Greg Clayton 9efa076aa6 Save more memory by not parsing the symbol table for stand alone DWARF files. We currently have SymbolFile plug-ins which all get the chance to say what they can parse in a symbol file. Prior to this fix we would ask the SymbolFileDWARF plug-in what abilities it had, and it would answer with "everything", and then we would check the SymbolFileSymtab plug-in what abilities it had, in case it had more abilities. The checking that SymbolFileSymtab does is a bit expensive as it pulls in the entire symbol table just to see if it can offer a few scraps of debug information. This causes all stand along DWARF files to pull in their symbol tables even though those symbols will never be used. This fix will check all SymbolFile plug-ins for their abilities and if any plug-in responds with "everything", then we stop the search.

DWARFCompileUnit.cpp
Added the ability to log a message with a backtrace when verbose logging is enabled to the Module class. Used this new function in the DWARF parser.

DWARFDebugAranges.cpp
Added more functionality to Range template classes in RangeMap.h and converted remaining DWARF areas that were using ranges over to this class. Also converted lldb_private::Block to use it.
2011-10-08 00:49:15 +00:00
DWARFDebugAranges.h
Changed RangeMap over to use llvm::SmallVector and updated the RangeArray and the RangeDataArray to have an extra "unsigned N" template parameter. Updated the lldb_private::Block to use a RangeArray with a uint32_t for both the function base offset and block range size, and then a 1 for the small vector size since most lexical blocks in DWARF only have 1 range. Updates the DWARFDebugRanges RangeArray to use an unsigned of 2 since most blocks that have more than one range usually have 2. Also updated a DWARFDebugAranges to default their RangeArray to use a SmallVector with unsigned size of 1 since this will take care of the .o files when doing DWARF in .o files and since there really isn't any good size we can guess with.

DWARFDebugArangeSet.cpp
…
DWARFDebugArangeSet.h
Since we use address ranges a lot I added a templatized class that allows us to easily control the base address type, the size type, and the data that is stored with each range. It is designed to be populated by appending all needed items, then sorting the resulting list, and optionally minimizing the list when done. I adopted this new list in the DWARFDebugAranges for even further memory savings.
