We can use this to connect items which must stay in the .o file (e.g. pubnames and pubtypes) to the skeleton cu rather than having duplicate unique numbers for the sections and needing to do lookups based on MDNode. llvm-svn: 189293

| | | | | | | | | | | | | | | | | | | | | | | .debug_pubtypes version field Summary: LLVM would generate DWARF with version 3 in the .debug_pubname and .debug_pubtypes version fields. This would lead SGI dwarfdump to fail parsing the DWARF with (in the instance of .debug_pubnames) would exit with: dwarfdump ERROR: dwarf_get_globals: DW_DLE_PUBNAMES_VERSION_ERROR (123) This fixes PR16950.

* Turn on pubnames by default on linux.Eric Christopher2013-08-191-10/+21
| | | | | | | | | 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. llvm-svn: 188708

* Fix a memory leak in the debug emission by simply not allocating memory.Chandler Carruth2013-07-271-2/+2

* Add preliminary support for hashing DIEs and breaking them intoEric Christopher2013-07-261-0/+149
| | | | | | | | | | | | | | | | type units. Initially this support is used in the computation of an ODR checker for C++. For now we're attaching it to the DIE, but in the future it will be attached to the type unit. This also starts breaking out types into the separation for type units, but without actually splitting the DIEs. In preparation for hashing the DIEs this adds a DIEString type that contains a StringRef with the string contained at the label. llvm-svn: 187213

| | | | | | | | | | | | | | | Change the informal convention of DBG_VALUE machine instructions so that we can express a register-indirect address with an offset of 0. The old convention was that a DBG_VALUE is a register-indirect value if the offset (operand 1) is nonzero. The new convention is that a DBG_VALUE is register-indirect if the first operand is a register and the second operand is an immediate. For plain register values the combination reg, reg is used. MachineInstrBuilder::BuildMI knows how to build the new DBG_VALUES. rdar://problem/13658587 llvm-svn: 185966
