* llvm-dwarfdump: Add support for dumping the .debug_loc sectionDavid Blaikie2013-06-191-0/+1
| | | | | | | | | This is a basic implementation - we still don't have any support (that I know of) for dumping DWARF expressions in a meaningful way, so the location information itself is just printed as a sequence of bytes as we do elsewhere. llvm-svn: 184361
* Add support for the pubnames section to llvm-dwarfdump.Krzysztof Parzyszek2013-02-121-0/+1

* When encountering an unknown file format, ObjectFile::createObjectFile shouldEli Bendersky2013-01-251-0/+5
| | | | | | | | | politely report it instead of running into llvm_unreachable. Also patch llvm-dwarfdump to actually check whether the file it's attempting to dump is a valid object file. llvm-svn: 173489
* Add command-line flags for DWARF dumping.Eli Bendersky2013-01-251-1/+18
| | | | | | | Flags for dumping specific DWARF sections added in lib/DebugInfo and llvm-dwarfdump. llvm-svn: 173480
* Rename variable to be more comprehensible and follow naming conventionEli Bendersky2013-01-251-4/+4

* Sort the #include lines for tools/...Chandler Carruth2012-12-041-2/+2
| | | | | | | | Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. llvm-svn: 169252
* Rewrite DIContext interface to take an object. Update all callers.Eric Christopher2012-11-121-93/+1

| | | | | | DIContext. This is needed to prevent crashes because of dangling reference if the clients don't provide RelocMap to DIContext constructor. llvm-svn: 167728
* Add a relocation visitor to lib object. This works via caching relocatedEric Christopher2012-11-071-1/+58
| | | | | | | values in a map that can be passed to consumers. Add a testcase that ensures this works for llvm-dwarfdump. llvm-svn: 167558
* Formatting and 80-col.Eric Christopher2012-10-161-3/+3

* Add support for fetching inlining context (stack of source code locations)Alexey Samsonov2012-09-041-9/+32
| | | | | | | | | | | by instruction address from DWARF. Add --inlining flag to llvm-dwarfdump to demonstrate and test this functionality, so that "llvm-dwarfdump --inlining --address=0x..." now works much like "addr2line -i 0x...", provided that the binary has debug info (Clang's -gline-tables-only *is* enough). llvm-svn: 163128
* Add basic support for .debug_ranges section to LLVM's DebugInfo library.Alexey Samsonov2012-08-271-1/+5
| | | | | | | | | | | This section (introduced in DWARF-3) is used to define instruction address ranges for functions that are not contiguous and can't be described by low_pc/high_pc attributes (this is the usual case for inlined subroutines). The patch is the first step to support fetching complete inlining info from DWARF. Reviewed by Benjamin Kramer. llvm-svn: 162657
* DebugInfo library: add support for fetching absolute paths to source filesAlexey Samsonov2012-07-191-1/+2

* This patch extends the libLLVMDebugInfo which contains a minimalistic DWARF ↵Alexey Samsonov2012-07-021-1/+12
| | | | | | | | | | parser: 1) DIContext is now able to return function name for a given instruction address (besides file/line info). 2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag). 3) test case that checks the basic functionality of llvm-dwarfdump added llvm-svn: 159512
* Fix a few changes I missed.Michael J. Spencer2011-10-071-3/+3

* DWARF: Port support for parsing .debug_aranges section from LLDB and wire it ↵Benjamin Kramer2011-09-141-1/+5
| | | | | | | | | up to llvm-dwarfdump. This is only one half of it, the part that caches address ranges from the DIEs when .debug_aranges is not available will be ported soon. llvm-svn: 139680
* Sketch out a DWARF parser.Benjamin Kramer2011-09-131-0/+93
This introduces a new library to LLVM: libDebugInfo. It will provide debug information parsing to LLVM. Much of the design and some of the code is taken from the LLDB project. It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an object file. It can be used to write tests for DWARF input and output easily. llvm-svn: 139627
