It is confirmed also in gcc mainline branch:
tst-tls1.c: In function ‘check_s’:
tst-tls1.c:65:1: error: unrecognizable insn:
(insn 36 35 37 6 (set (reg/f:SI 163)
(plus:SI (plus:SI (reg:SI 25 r25)
(reg:SI 164))
(const_int 512 [0x200]))) "tst-tls1.c":64:3 -1
(expr_list:REG_EQUAL (const:SI (plus:SI (symbol_ref:SI ("s") [flags 0x22]
<var_decl 0x7f7f85da2120 s>)

(nil)))
during RTL pass: vregs
