--- Comment #26 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So I guess this is mine too.
With my patches I created to improve PR 109907 (attached there), the initial
RTL now looks like:
;; _9 = (unsigned char) _8;
(insn 6 5 0 (set (reg/v:QI 46 [ <retval> ])
(zero_extract:QI (subreg:QI (reg/v:SI 47 [ number ]) 3)
(const_int 1 [0x1])
(const_int 5 [0x5]))) "t2.c":4:6 -1
(nil))
Where it was before:
;; _9 = (unsigned char) _8;
(insn 6 5 7 (set (reg:SI 48)
(lshiftrt:SI (reg/v:SI 47 [ number ])
(const_int 29 [0x1d]))) "t2.c":4:6 -1
(nil))
(insn 7 6 0 (set (reg/v:QI 46 [ <retval> ])
(and:QI (subreg:QI (reg:SI 48) 0)
(const_int 1 [0x1]))) "t2.c":4:6 -1
(nil))
