Bug ID: 28697
Summary: objdump doesn't look for separate debug styles using
"build-id" style
Product: binutils
Version: 2.37
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org

uses the debuglink and build-id styles to build and strip a binary
Support for the "build ID" style of separate debug lookup was added in 2017:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=2425a30e406a0523020b7e70abb864a06a45bb97
However, it seems to be used only for a few flags like -S, but it is ignored
for others, like --syms.
Using strace, one can see that for --syms it is only looks for the old style
"debuglink" debug info. It never looks in the `.build-id` based paths even when
the note is present.
Find below a test program which shows the issue, based on strace output, chmod
+x it and run.
