[PATCH 0/4] Improve debugging of optimized code

[Bernd Edlinger]

I've rebased and re-tested the following patches
which are trying to improve the debug experience of
optimized gcc code.  All have been posted previously
but I have been asked to post them again as a patch
series.

Only [2/4] depends on [1/4], these are about stepping
in inlined code.
The patches [3/4] and [4/4] are about breakpoints,
those do not depend on each other.

Bernd Edlinger (4):
  Introduce a new line table flag is_weak
  Fix range end handling of inlined subroutines
  Fix handling of DW_AT_entry_pc of inlined subroutines
  Skip .cold functions in search_minsyms_for_name
