* [DWARF parser] Use distinction between DW_AT_ranges_base and ↵Alexey Samsonov2014-06-13

* [DWARF parser] Teach DIContext to fetch short (non-linkage) function names ↵Alexey Samsonov2014-05-17
| | | | | | | | | | | for a given address. Change --functions option in llvm-symbolizer tool to accept values "none", "short" or "linkage". Update the tests and docs accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209050 91177308-0d34-0410-b5e6-96231b3b80d8
* [DWARF parser] Use enums instead of bitfields in DILineInfoSpecifier.Alexey Samsonov2014-05-15
| | | | | | | | | | | | | It is more appropriate than the current situation, when one flag (AbsoluteFilePath) is relevant only if another flag is set. This refactoring would also simplify fetching the short function name (stored in DW_AT_name) instead of a linkage name returned currently. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208921 91177308-0d34-0410-b5e6-96231b3b80d8

* [DWARF parser] Refactor fetching DIE address ranges.Alexey Samsonov2014-04-18
| | | | | | | | | | | Add a helper method to get address ranges specified in a DIE (either by DW_AT_low_pc/DW_AT_high_pc, or by DW_AT_ranges). Use it to untangle and simplify the code.

* DebugInfo: Introduce the notion of "form classes"Alexey Samsonov2013-10-28
| | | | | | | | | | | | | | | | | | 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.

* Sketch out a DWARF parser.Benjamin Kramer2011-09-13
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
