It is quiet possible that inlined function body is split into multiple chunks of consequtive instructions. But, there is not any way to describe this in .debug_inline accelerator table used by gdb. However, describe non contiguous ranges of inlined function body appropriately using AT_range of DW_TAG_inlined_subroutine debug info entry.

There are two ways to map a variable to its lexical scope. Lexical scope information is embedded in MDNode describing the variable. It is also available as a part of DebugLoc attached with DBG_VALUE instruction. DebugLoc attached with an instruction is less reliable in optimized code so use information embedded in the MDNode.
