Subject: [Bug gdb/28004] DW_AT_ranges with form DW_FORM_sec_offset problem
Date: Fri, 25 Jun 2021 12:47:08 +0000 [thread overview]
Message-ID: <bug-28004-4717-3yLD14WPBK@http.sourceware.org/bugzilla/> (raw)

--- Comment #2 from Tom de Vries <vries at gcc dot gnu.org> ---
The warning is caused by the fact that the addr map for the CU starts at 0, due
to the DW_AT_entry_pc:
...
<2><50bea>: Abbrev Number: 13 (DW_TAG_inlined_subroutine)
<50beb> DW_AT_abstract_origin: <0x50b99>
<50bef> DW_AT_entry_pc : 0x0
<50bf7> DW_AT_GNU_entry_view: 0
<50bf9> DW_AT_ranges : 0x3db4
<50bfd> DW_AT_call_file : 1
<50bfe> DW_AT_call_line : 64
<50bff> DW_AT_call_column : 9
<50c00> DW_AT_sibling : <0x50c26>
...
Or, likewise, DW_AT_ranges:
...
0x00003db4: [DW_RLE_base_address]: 0x0000000000000000
0x00003dbd: [DW_RLE_offset_pair ]: 0x0000000000000000, 0x0000000000000007 =>
[0x0000000000000000, 0x0000000000000007)
0x00003dc0: [DW_RLE_offset_pair ]: 0x000000000000000b, 0x0000000000000018 =>
[0x000000000000000b, 0x0000000000000018)
0x00003dc3: [DW_RLE_end_of_list ]
...
