Not sufficient it seems, you also need to move the potential relocation of the
insn in the delay slot. The example I have is:
0x00014188 <+232>: add %g7, %o0, %o0
0x0001418c <+236>: sethi %hi(0), %l0
0x00014190 <+240>: ld [ %o0 ], %g1
before the change and:
0x00014188 <+232>: sethi %hi(0), %l0
0x0001418c <+236>: add %g0, %g0, %o0
0x00014190 <+240>: ld [ %o0 ], %g1
after, because of a R_SPARC_TLS_GD_HI22 relocation attached to the insn.
