            Bug ID: 28592
           Summary: objdump -d --source is very slow with certain ELF
           Product: binutils
           Version: 2.38 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: jcmvbkbc at gcc dot gnu.org
  Target Milestone: ---

Hello,

I have an ELF file that goes through the binutils-2.37 objdump -d --source in
about a minute, but through the same command of binutils-2.23.2 in about 4
seconds. The output in both cases is identical. Unfortunately I cannot share
that ELF file. Bisection points to the following commit as the reason for the
slowdown:
