Benjamin Kramer a57c46aa49 DWARF: Include <algorithm> explicitly. 
llvm-svn: 139773
 2011-09-15 02:19:33 +00:00
Benjamin Kramer 5acab501de DWARF: Add basic support for line tables. 
The llvm-dwarfdump output isn't very verbose yet.

Benjamin Kramer 3266493603 DWARF: Generate the address lookup table from the DIE tree if .debug_aranges is not available. 
Ported from LLDB.

Benjamin Kramer f915acc613 DWARF: Improve indentation of DIE dumping so it's easier to see the structure.

Benjamin Kramer 973b5cde7e llvm-dwarfdump: Make the "is debug info section" heuristic stricter so it doesn't accidentaly picks up the wrong section. 
Also add some validation code to the aranges section parser.

Fixes PR10926.

Benjamin Kramer a9e7fb678d Don't rely in <algorithm> being pulled in transitively.

Benjamin Kramer a6002fd920 DWARF: Port support for parsing .debug_aranges section from LLDB and wire it 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.

Benjamin Kramer aa2f78f5e6 Sketch out a DWARF parser. 
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.
