That is not EQUIV related case. SET_GOT is removed by CSE called at IRA.
Here we have insn that don't use GOT register implicitly:
(insn 37 34 38 6 (set (mem:TF (pre_dec:SI (reg/f:SI 7 sp)) [0 S16 A8])
(const_double:TF 2.0769187434139310514121985316880384e+34
[0x0.8p+115])) frexpq.c:1316 121 {*pushtf}
(expr_list:REG_ARGS_SIZE (const_int 16 [0x10])
(nil)))
It appears that there are no other insns using GOT or calls.
Therefore CSE absolutely correct in removing SET_GOT.
