> Log:
> Add basic support for .debug_ranges section to LLVM's DebugInfo library.
> 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.

It was i686-unsafe. Fixed in r162665.
