* Merge DWARFDIE::extractFast and DWARFDIE::extract into one function.Alexey Samsonov2013-10-281-6/+0
| | | | | | | | Complicated CU-DIE-specific logic in the latter was never used, and it makes sense to have safety checks for broken dwarf in the former. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193563 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Introduce the notion of "form classes"Alexey Samsonov2013-10-281-2/+7
| | | | | | | | | | | | | | | | | | Summary: Use DWARF4 table of form classes to fetch attributes from DIE in a more consistent way. This shouldn't change the functionality and serves as a refactoring for upcoming change: DW_AT_high_pc has different semantics depending on its form class.

* Add support for DebugFission to DWARF parserAlexey Samsonov2013-08-271-1/+6
| | | | | | | | | | | | | | | | | | | Summary: 1) Make llvm-symbolizer properly symbolize files with split debug info (by using stanalone .dwo files). 2) Make DWARFCompileUnit parse and store corresponding .dwo file, if necessary. 3) Make bits of DWARF parsing more CompileUnit-oriented.

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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163128 91177308-0d34-0410-b5e6-96231b3b80d8

* Sketch out a DWARF parser.Benjamin Kramer2011-09-131-0/+131
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139627 91177308-0d34-0410-b5e6-96231b3b80d8
