Bug ID: 29266
Summary: readelf ..info misreports DW_FORM_strxN
Product: binutils
Version: 2.39 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: sevaa at sprynet dot com
Target Milestone: ---
Created attachment 14153

Test binary and sources
Consider the debug information in the attached binary. It consists of two
compilation units - foo.cpp and bar.cpp. Run "readelf --debug-dump=info foo"
with the latest master as of 2022-06-20. It reports the value of DW_AT_name as
"foo.cpp" for both compilation units. That can't be right.
Internally, it looks as if the logic of resolving DW_FORM_strx,
DW_FORM_strx1..4 form attributes looks into the portion of the
debug_str_offsets section that pertains to the top CU as opposed to the current
CU. Elsewhere, it also causes numerous bogus warnings like
"DW_FORM_GNU_str_index offset too big: 0x1350 vs 0xbf0", where the str_offset
count in the current CU is greater than that in the top CU.
