Hello,
at least Fedora Linux distribution uses DWZ to reduce DWARF debug info size:
https://fedoraproject.org/wiki/Features/DwarfCompressor
It is DWARF optimization - not really a compression. One can find it by
DW_TAG_partial_unit/DW_TAG_imported_unit:
<0><b>: Abbrev Number: 103 (DW_TAG_partial_unit)
<c> DW_AT_stmt_list : 0x0
<10> DW_AT_comp_dir : (alt indirect string, offset: 0xe61c)
<1><14>: Abbrev Number: 45 (DW_TAG_imported_unit)
<15> DW_AT_import : <alt 0xb>
...
LLDB (incl. trunk) does not support it and it even crashes on DWZed files.
Is anyone working on this support? To prevent possible work duplication.
I have found only this commit but that is not really for LLDB:
