Date: Fri, 19 Feb 2021 11:43:28 +0000 [thread overview]
Message-ID: <bug-27440-11298@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=27440
Bug ID: 27440
Summary: [dwz, dwarf5] Add --dwarf-5 flag to generate
.debug_sup, ref_sup and strp_sup
Product: dwz
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: default
Assignee: nobody at sourceware dot org
Reporter: mark at klomp dot org
CC: dwz at sourceware dot org
Blocks: 24726
Target Milestone: ---
Currently the dwz multi-files are really DWARF4 + GNU extensions. Since the
format and references were formalized in the DWARF5 spec as DWARF Supplementary
Object Files (DWARF5 section 7.3.6) it would be nice to have a way to generate
this format with a --dwarf-5 flag:
- Use DW_FORM_ref_sup[48] and DW_FORM_strp_sup instead of
DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt
- Generate .debug_sup section (standardized variant of .gnu_debugaltlink)
