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.
