--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
And there is one more important insn in between 2737 and 2275, in particular
(insn 2911 2867 2853 2 (set (reg:DI 42 r14 [2223])
        (const_int 72057594037927935 [0xffffffffffffff])) "pr100342.c":68:12 66
{*movdi_internal}
     (nil))
On that one the old value of r14 is lost.
