            Bug ID: 22728
           Summary: Incorrect local symbols generated on Solaris
           Product: binutils
           Version: 2.31 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---
            Target: *-*-solaris

emulparams/solaris2.sh has

# The Solaris 2 ABI requires that two local symbols are present in every
# executable and shared object.
# Cf. Linker and Libraries Guide, Ch. 2, Link-Editor, Generating the Output
# File, p.63.
TEXT_START_SYMBOLS='_START_ = .;'
OTHER_END_SYMBOLS='_END_ = .;'

But ld generates:
