Bug ID: 115235
Summary: Non-standard .debug_addr section
Product: gcc
Version: 13.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: llvm at rifkin dot dev
Target Milestone: ---
I'm trying to use -gsplit-dwarf however I'm running into a lot of tooling
problems because as far as I can tell the .debug_addr is being generated in a
different format than specified by the dwarf 5 standard. It seems the format
described in https://gcc.gnu.org/wiki/DebugFission is being used. This is
causing problems with tooling expecting the dwarf 5 format for the section.
Even with -gsplit-dwarf -gdwarf-5 a non-standard .debug_addr section is
generated.
An example hexdump:
Hex dump of section '.debug_addr':

Is there any way to get gcc to emit the section as described by the standard?
Is there any way to tell from other debug information that a non-standard
encoding should be expected here?
