;; __u.__d = __x_1(D);
(insn 6 5 0 t.c:15 (set (subreg:DF (reg/v:DI 60 [ __u ]) 0)
(reg/v:DF 62 [ __x ])) -1 (nil))
That causes a reload to happen:
Reload 0: reload_out (DF) = (subreg:DF (reg/v:DI 60 [ __u ]) 0)
FLOAT_REGS, RELOAD_FOR_OUTPUT (opnum = 0)
reload_out_reg: (subreg:DF (reg/v:DI 60 [ __u ]) 0)
reload_reg_rtx: (reg:DF 8 st)
I think I might have another bug about this issue before ...
