2013-04-25Clarify getRelocationAddress x getRelocationOffset a bit.Rafael Espindola
getRelocationAddress is for dynamic libraries and executables, getRelocationOffset for relocatable objects. Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a test of ELF's. llvm-readobj -r now prints the same values as readelf -r. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180259 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-23Use zlib to uncompress debug sections in DWARF parser.Alexey Samsonov
This makes llvm-dwarfdump and llvm-symbolizer understand debug info sections compressed by ld.gold linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180088 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-17Create a stub for DWARF parser unittestsAlexey Samsonov
Moves one DWARF-specific header to include/llvm/DebugInfo from lib/. Add a short unittest for r179095. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179678 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-11Rename the C function to create a SLPVectorizerPass to something sane and ↵Benjamin Kramer
expose it in the header file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179272 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-09DWARF parser: Fix DWARF-2/3 incompatibility: size of DW_FORM_ref_addr is the ↵Alexey Samsonov
same as DW_FORM_addr in DWARF2, and is 4/8 bytes on 32/64-bit DWARF starting from DWARF3. Adding a test for this is a huge pain - generating and uploading pre-built binary with DWARF3 debug info is way too ugly, and writing fine-grained unittests for DebugInfo is impossible, as it doesn't expose any headers in include/llvm. That said, I'm going to choose the second approach and submit the patch exposing DebugInfo headers for review soon enough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179095 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-07DW_FORM_sec_offset should be a relocation on platforms that useEric Christopher
a relocation across sections. Do this for DW_AT_stmt list in the skeleton CU and check the relocations in the debug_info section. Add a FIXME for multiple CUs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178969 91177308-0d34-0410-b5e6-96231b3b80d8

member variable. Patch by Kai <kai@redstar.de> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177575 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22Code cleanup: pass Offset by pointer to parseInstruction to more explicitlyEli Bendersky
convey that it's a INOUT argument. Also, if parsing of entry instructions fails, don't push the entry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175847 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Previously, parsing capability of the .debug_frame section was addedEli Bendersky
to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds initial ability to parse and dump CFA instructions contained in entries. To keep it manageable, the patch omits some more advanced capabilities (accounted in TODOs): * Parsing of instructions with BLOCK arguments (expression lists) * Dumping of actual instruction arguments (currently only names are dumped). This is quite tricky since the dumper has to effectively "interpret" the instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175820 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08The patch to fix some issues in r174543 fixed the lines failing the test, ↵David Tweed
but missed a couple of lines which weren't being explicitly looked at and were printing incorrect results. These values clearly must lie within 32 bits, so the casts are definitely safe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174717 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

2013-01-07Add 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

2013-01-02Extend the dumping infrastructure to deal with additionalEric Christopher
sections for debug info. These are some of the dwo sections from the DWARF5 split debug info proposal. Update the fission-cu.ll testcase to show what we should be able to dump more of now. Work in progress: Ultimately the relocations will be gone for the dwo section and the strings will be a different form (as well as the rest of the sections will be included). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171428 91177308-0d34-0410-b5e6-96231b3b80d8
