--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

This code I think is broken:

2724d1bba6b3 gcc/tree-ssa-forwprop.c  (Richard Biener        2021-07-30
11:06:50 +0200 3205)      /* Perform scalar promotion.  */
2724d1bba6b3 gcc/tree-ssa-forwprop.c  (Richard Biener        2021-07-30
11:06:50 +0200 3206)      new_stmt = gimple_build_assign (gimple_assign_lhs
(use_stmt),
2724d1bba6b3 gcc/tree-ssa-forwprop.c  (Richard Biener        2021-07-30
11:06:50 +0200 3207)                                      NOP_EXPR, tem);


So this is most likely introduced by r12-2728-g2724d1bba6b364 .
