Sorry, there was an automation bug, this is the correct commit list.

These are all good fixes and improve DWARF parsing and also increases our ability to debug with GCC. These would be great candidates to backport.

[jankratochvil]

FYI I have found yesterday it does not really fix it in practice as it currently works only for a single CU. Still it should not harm. I will provide another patch to fix it for real.

[jankratochvil]

I would recommend not to backport it before I make the new patch for trunk (if it gets done in time for a backport). This patchset is not really useful in its current form anyway.

The real fix is submitted, not yet checked-in:

[llvm+lldb] 2/2: Fix#2 of DW_AT_ranges DW_FORM_sec_offset not using DW_AT_rnglists_base (used by GCC)
https://reviews.llvm.org/D106466

It is on top of the previous patches (in the end I did not revert them).
