2013-02-06Attempt to recover gdb bot after r174445.Manman Ren
Failure: undefined symbol 'Lline_table_start0'. Root-cause: we use a symbol subtraction to calculate at_stmt_list, but the line table entries are not dumped in the assembly. Fix: use zero instead of a symbol subtraction for Compile Unit 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174479 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05Dwarf: support for LTO where a single object file can have multiple line tablesManman Ren

DWARF5 split dwarf proposal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174350 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-31[Dwarf] early exit to avoid creating dangling DIEsManman Ren
We used to create children DIEs for a scope, then check whether ScopeDIE is null. If ScopeDIE is null, the children DIEs will be dangling. Other DIEs can link to those dangling DIEs, which are not emitted at all, causing dwarf error. The current testing case is 4k lines, from MultiSource/BenchMark/McCat/09-vor. rdar://problem/13071959 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174084 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-17Fix the assembly and dissassembly of DW_FORM_sec_offset. Found this byEric Christopher
changing both the string of the dwo_name to be correct and the type of the statement list. Testcases all around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172699 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-17Add the DW_AT_GNU_addr_base for the skeleton cu. Add support forEric Christopher
emitting the dwarf32 version of DW_FORM_sec_offset and correct disassembler support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172698 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Split address information for DWARF5 split dwarf proposal. This involvesEric Christopher
using the DW_FORM_GNU_addr_index and a separate .debug_addr section which stays in the executable and is fully linked. Sneak in two other small changes: a) Print out the debug_str_offsets.dwo section. b) Change form we're expecting the entries in the debug_str_offsets.dwo section to take from ULEB128 to U32. Add tests for all of this in the fission-cu.ll test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172578 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Last in the series of removing unnecessary '0' arguments forEric Christopher
address space. Reordered the EmitULEB128IntValue arguments to make this easier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171949 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Add support for separating strings for the split debug info DWARF5Eric Christopher
proposal. This leaves the strings in the skeleton die as strp, but in all dwo files they're accessed now via DW_FORM_GNU_str_index. Add support for dumping these sections and modify the fission-cu.ll testcase to have the correct strings and form. Fix a small bug in the fixed form sizes routine that involved out of array accesses for the table and add a FIXME in the extractFast routine to fix this up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171779 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-10Refactor out the abbreviation handling into a separate class thatEric Christopher
controls each of the abbreviation sets (only a single one at the moment) and computes offsets separately as well for each set of DIEs. No real function change, ordering of abbreviations for the skeleton CU changed but only because we're computing in a separate order. Fix the testcase not to care. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169793 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Reapply r160148 (reverted in r163570) fixing spurious breakpoints in modern GDBDavid Blaikie
This reapplies the fix for PR13303 now with more justification. Based on my execution of the GDB 7.5 test suite this results in: expected passes: 16101 -> 20890 (+30%) unexpected failures: 4826 -> 637 (-77%) There are 23 checks that used to pass and now fail. They are all in gdb.reverse. Investigating a few looks like they were accidentally passing due to extra breakpoints being set by this bug. They're generally due to the difference in end location between gcc and clang, the test suite is trying to set breakpoints on the closing '}' that clang doesn't associate with any instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169304 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
