            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
          Reporter: travis.downs at gmail dot com
  Target Milestone: ---

Created attachment 13856
  --> https://sourceware.org/bugzilla/attachment.cgi?id=13856&action=edit
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.
