* Sink DwarfDebug::constructInlinedScopeDIE into DwarfCompileUnitDavid Blaikie2014-10-091-1/+31
| | | | | | | | | | | This introduces access to the AbstractSPDies map from DwarfDebug so DwarfCompileUnit can access it. Eventually this'll sink down to DwarfFile, but it'll still be generically accessible - not much encapsulation to provide it. (constructInlinedScopeDIE could stay further up, in DwarfFile to avoid exposing this - but I don't think that's particularly better) llvm-svn: 219411

* Sink DwarfDebug::addScopeRangeList down into DwarfCompileUnitDavid Blaikie2014-10-091-0/+26
| | | | | | | | | | | | | (& add a few accessors/make a couple of things public for this - it's a bit of a toss-up, but I think I prefer it this way, keeping some more of the meaty code down in DwarfCompileUnit - if only to make for smaller implementation files, etc) I think we could simplify range handling a bit if we removed the range lists from each unit and just put a single range list on DwarfDebug, similar to address pooling. llvm-svn: 219370

* Push DwarfDebug::constructScopeDIE down into DwarfCompileUnitDavid Blaikie2014-10-081-0/+59
| | | | | | | | | | One of many steps to generalize subprogram emission to both the DWO and non-DWO sections (to emit -gmlt-like data under fission). Once the functions are pushed down into DwarfCompileUnit some of the data structures will be pushed at least into DwarfFile so that they can be unique per-file, allowing emission to both files independently. llvm-svn: 219345
* Sink DwarfDebug::updateSubprogramScopeDIE into DwarfCompileUnitDavid Blaikie2014-10-041-0/+30
| | | | | | | | | | | | | This requires exposing some of the current function state from DwarfDebug. I hope there's not too much of that to expose as I go through all the functions, but it still seems nicer to expose singular data down to multiple consumers, than have consumers expose raw mapping data structures up to DwarfDebug for building subprograms. Part of a series of refactoring to allow subprograms in both the skeleton and dwo CUs under Fission. llvm-svn: 219060

* Sink DwarfDebug::attachLowHighPC into DwarfCompileUnitDavid Blaikie2014-10-041-0/+14
| | | | | | | One of many things to sink down into DwarfCompileUnit to allow handling of subprograms in both the skeleton and dwo CU under Fission. llvm-svn: 219058
* Move DwarfCompileUnit from DwarfUnit.h to its own header (DwarfCompileUnit.h)David Blaikie2014-10-041-0/+277
| | | | | | | | | | | | In preparation for sinking all the subprogram emission code down from DwarfDebug into DwarfCompileUnit, this will avoid bloating DwarfUnit.h/cpp greatly and make concerns a bit more clear/isolated. (sinking this handling down is part of the work to handle emitting minimal subprograms for -gmlt-like data into the skeleton CU under fission) llvm-svn: 219057

| | | | | | | | | | registration. It might be possible to eventually use one data structure, but I haven't looked at the exact criteria used for accelerator tables and pubtypes to see if there's good reason for the differences between the two or not. llvm-svn: 195696
* In Dwarf 3 (and Dwarf 2) attributes whose value are offsets into aEric Christopher2013-11-211-9/+29
| | | | | | | | | | | | | | | | | | | | | section use the form DW_FORM_data4 whilst in Dwarf 4 and later they use the form DW_FORM_sec_offset. This patch updates the places where such attributes are generated to use the appropriate form depending on the Dwarf version. The DIE entries affected have the following tags: DW_AT_stmt_list, DW_AT_ranges, DW_AT_location, DW_AT_GNU_pubnames, DW_AT_GNU_pubtypes, DW_AT_GNU_addr_base, DW_AT_GNU_ranges_base It also adds a hidden command line option "--dwarf-version=<uint>" to llc which allows the version of Dwarf to be generated to override what is specified in the metadata; this makes it possible to update existing tests to check the debugging information generated for both Dwarf 4 (the default) and Dwarf 3 using the same metadata.

* DwarfCompileUnit: Initialize DebugInfoOffset.David Blaikie2013-11-201-2/+2
| | | | | | | | | | | | While not strictly necessary (the class has an invariant that "setDebugInfoOffset" is called before "getDebugInfoOffset" - anyone client that actually gets the default zero offset is buggy/broken) this is consistent with the code as originally written and the removal of the initialization was an accident in r195166.

* DebugInfo: Partial implementation of DWARF type units.David Blaikie2013-11-191-10/+47
| | | | | | | | | | | | | | Emit DW_TAG_type_units into the debug_info section using compile unit headers. This is bogus/unusable by debuggers, but testable and provides more isolated review. Subsequent patches will include support for type unit headers and emission into the debug_types section, as well as comdat grouping the types based on their hash. Also the CompileUnit type will be renamed 'Unit' and relevant portions pulled out into respective CompileUnit and TypeUnit types. llvm-svn: 195166
