* Turn on pubnames by default on linux.Eric Christopher2013-08-192-1/+131
| | | | | | | | | 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. On darwin we already emit the accelerator tables and so don't need to worry about pubnames. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188708 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-dwarfdump: Do not include address offsets for attributes, only for tagsDavid Blaikie2013-08-197-20/+20
| | | | | | | | | This reduces the noise in diffs making it more likely that, at least for LLVM revision-over-revision, diffs will actually yield usable results. This is consistent with objdump's DWARF dumping behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188650 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: don't emit zero-length names for parametersDavid Blaikie2013-08-191-3/+5
| | | | | | | | We check this in many/all other cases, just missed this one it seems. Perhaps it'd be worth unifying this so we never emit zero-length DW_AT_names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188649 91177308-0d34-0410-b5e6-96231b3b80d8
* [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

* Debug Info Finder|Verifier: handle DbgLoc attached to instructions.Manman Ren2013-08-064-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also remove checking of llvm.dbg.sp since it is not used in generating dwarf. Current state of Finder: DebugInfoFinder tries to list all debug info MDNodes used in a module. To list debug info MDNodes used by an instruction, DebugInfoFinder provides processDeclare, processValue and processLocation to handle DbgDeclareInst, DbgValueInst and DbgLoc attached to instructions. processModule will go through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes used by the CUs. TODO: 1> Finder has a list of CUs, SPs, Types, Scopes and global variables.
