            Bug ID: 22740
           Summary: sparc linker does not honor --no-relax
           Product: binutils
           Version: 2.29
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: rth at gcc dot gnu.org
  Target Milestone: ---

In bfd/elfxx-sparc.c, there are several code sequences that are
adjusted by various relocations.  None of them should occur when
we tell the linker not to change them.

In particular, R_SPARC_TLS_IE_LD{,X} should not optimize instructions
to NOP.  There is a current gcc bug with respect to emitting this
relocation; it would have been handy to work around the bug by turning
off the linker optimization.
