* Fix the representation of debug line table in DebugInfo LLVM library,Alexey Samsonov2012-08-072-0/+6
| | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | DwarfDebug class could generate the same (inlined) DIVariable twice: 1) when trying to find abstract debug variable for a concrete inlined instance. 2) when explicitly collecting info for variables that were optimized out.
