2012-08-27[DebugInfo] fixup for r162657: update CMakeLists.txtAlexey Samsonov

2012-08-27Add basic support for .debug_ranges section to LLVM's DebugInfo library.Alexey Samsonov
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.

2012-08-07Fix the representation of debug line table in DebugInfo LLVM library,Alexey Samsonov
and "instruction address -> file/line" lookup. Instead of plain collection of rows, debug line table for compilation unit is now treated as the number of row ranges, describing sequences (series of contiguous machine instructions). The sequences are not always listed in the order of increasing address, so previously used std::lower_bound() sometimes produced wrong results. Now the instruction address lookup consists of two stages: finding the correct sequence, and searching for address in range of rows for this sequence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161414 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Sketch out a DWARF parser.Benjamin Kramer
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
