* Debug Info: Use identifier to reference DIType in base type field ofManman Ren2013-09-051-0/+29
| | | | | | | | | | | | | | | | | | | | | | | ptr_to_member. We introduce a new class DITypeRef that represents a reference to a DIType. It wraps around a Value*, which can be either an identifier in MDString or an actual MDNode. The class has a helper function "resolve" that finds the actual MDNode for a given DITypeRef. We specialize getFieldAs to return a field that is a reference to a DIType. To correctly access the base type field of ptr_to_member, getClassType now calls getFieldAs<DITypeRef> to return a DITypeRef. Also add a typedef for DITypeIdentifierMap and a helper generateDITypeIdentifierMap in DebugInfo.h. In DwarfDebug.cpp, we keep a DITypeIdentifierMap and call generateDITypeIdentifierMap to actually populate the map. Verifier is updated accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190081 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: add an identifier field to DICompositeType.Manman Ren2013-08-2691-279/+279
| | | | | | | | | | | | | | | | | | | DICompositeType will have an identifier field at position 14. For now, the field is set to null in DIBuilder. For DICompositeTypes where the template argument field (the 13th field) was optional, modify DIBuilder to make sure the template argument field is set. Now DICompositeType has 15 fields. Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode. Update verifier to check that DICompositeType has 15 fields and the last field is null or a MDString. Update testing cases to include an extra field for DICompositeType. The identifier field will be used by type uniquing so a front end can genearte a DICompositeType with a unique identifer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189282 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | Until gdb supports the new accelerator tables we should add the pubnames section so that gdb_index can be generated from gold at link time.

* [tests] Cleanup initialization of test suffixes.Daniel Dunbar2013-08-166-10/+0
| | | | | | | | | | | | | | | | | - Instead of setting the suffixes in a bunch of places, just set one master list in the top-level config. We now only modify the suffix list in a few suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py). - Aside from removing the need for a bunch of lit.local.cfg files, this enables 4 tests that were inadvertently being skipped (one in Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been XFAILED). - This commit also fixes a bunch of config files to use config.root instead of older copy-pasted code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188513 91177308-0d34-0410-b5e6-96231b3b80d8
