* Debug Info: remove duplication of DIEs when a DIE can be shared across CUs.Manman Ren2013-10-311-6/+14
| | | | | | | | | | | | | | | | | | | We add a map in DwarfDebug to map MDNodes that are shareable across CUs to the corresponding DIEs: MDTypeNodeToDieMap. These DIEs can be shared across CUs, that is why we keep the maps in DwarfDebug instead of CompileUnit. We make the assumption that if a DIE is not added to an owner yet, we assume it belongs to the current CU. Since DIEs for the type system are added to their owners immediately after creation, and other DIEs belong to the current CU, the assumption should be true. A testing case is added to show that we only create a single DIE for a type MDNode and we use ref_addr to refer to the type DIE. We also add a testing case to show ref_addr relocations for non-darwin platforms. llvm-svn: 193779
* DebugInfo: Push header handling down into CompileUnitDavid Blaikie2013-10-301-0/+11
| | | | | | | This is a preliminary step to handling type units by abstracting over all (type or compile) units. llvm-svn: 193714
* Debug Info: support for DW_FORM_ref_addr.Manman Ren2013-10-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support ref_addr, we calculate the section offset of a DIE (i.e. offset of a DIE from beginning of the debug info section). The Offset field in DIE is currently CU-relative. To calculate the section offset, we add a DebugInfoOffset field in CompileUnit to store the offset of a CU from beginning of the debug info section. We set the value in DwarfUnits::computeSizeAndOffset for each CompileUnit. A helper function DIE::getCompileUnit is added to return the CU DIE that the input DIE belongs to. We also add a map CUDieMap in DwarfDebug to help finding the CU for a given CU DIE. For a cross-referenced DIE, we first find the CU DIE it belongs to with getCompileUnit, then we use CUDieMap to get the corresponding CU for the CU DIE. Adding the section offset of the CU with the CU-relative offset of a DIE gives us the seciton offset of the DIE. We correctly emit ref_addr with relocation using EmitLabelPlusOffset when doesDwarfUseRelocationsAcrossSections is true. This commit handles the emission of DW_FORM_ref_addr when we have an attribute with FORM_ref_addr. A follow-on patch will start using ref_addr when adding a DIEEntry. This commit will be tested and verified in the follow-on patch. Reviewed off-list by Eric, Thanks. llvm-svn: 193658
* Debug Info: instead of calling addToContextOwner which constructs the contextManman Ren2013-10-291-3/+0
| | | | | | | | | | | | | | | after the DIE creation, we construct the context first. Ensure that we create the context before we create a type so that we can add the newly created type to the parent. Remove last use of addToContextOwner now that it's not needed. We use createAndAddDIE to wrap around "new DIE(". Now all shareable DIEs should be added to their parents right after the creation. Reviewed off-list by Eric, Thanks. llvm-svn: 193657
* Debug Info: add a helper function createAndAddDIE.Manman Ren2013-10-291-0/+4
| | | | | | | | | | | | | | It wraps around "new DIE(" and handles the bookkeeping part of the newly-created DIE. It adds the DIE to its parent, and calls insertDIE if necessary. It makes sure that bookkeeping is done at the earliest time and we should not see parentless DIEs if all constructions of DIEs go through this helper function. Later on, we can use an allocator for DIE allocation, and will only need to change createAndAddDIE instead of modifying all the "new DIE(". Reviewed off-list by Eric. llvm-svn: 193566

* Debug Info: code clean up.Manman Ren2013-10-231-9/+9
| | | | | | | | | | | Since we never insert DIE for DITemplateTypeParameter to a map, there is no need to call getDIE in getOrCreateTemplateTypeParameterDIE. It is also renamed to constructTemplateTypeParameterDIE to match with other construct functions in CompileUnit. Same applies to getOrCreateTemplateValueParameterDIE. llvm-svn: 193287

Add a routine that does a language specific context walk to build up the qualified name and use it when we add types/names to the tables.

* Debug Info: static member DIE creation.Manman Ren2013-10-141-2/+2
| | | | | | | | | | | | | Clean up creation of static member DIEs. We can create static member DIEs from two places, so we call getOrCreateStaticMemberDIE from the two places. getOrCreateStaticMemberDIE will get or create the context DIE first, then it will check if the DIE already exists, if not, we create the static member DIE and add it to the context. Creation of static member DIEs are handled in a similar way as subprogram DIEs. llvm-svn: 192618

* [DebugInfo] Introduce DIEExpr variant of DIEValue to hold MCExpr valuesUlrich Weigand2013-07-021-2/+5
| | | | | | | | | | | | This partially reverts r185202 and restores DIELabel to hold plain MCSymbol references. Instead, we add a new subclass DIEExpr of DIEValue that can hold generic MCExpr references. This is in preparation for supporting debug info for TLS variables on PowerPC, where we need to describe the variable location using a more complex expression than just MCSymbolRefExpr. llvm-svn: 185458
