CSE/GCSE should be doing it. Oh but CSE does not handle RTL like:
(insn 8 5 9 2 t.c:5 (set (mem:SI (reg/v/f:DI 60 [ c ]) [2 *c_2(D)+0 S4 A32])
(const_int -522133280 [0xffffffffe0e0e0e0])) 63 {*movsi_internal}
(nil))
Related to PR 23488.
What happens if you revert:
2005-07-30 Jan Hubicka <j...@suse.cz>
* expr.c (expand_expr_real_1): Do not load mem targets into register.
* i386.c (ix86_fixup_binary_operands): Likewise.
(ix86_expand_unary_operator): Likewise.
(ix86_expand_fp_absneg_operator): Likewise.
* optabs.c (expand_vec_cond_expr): Validate dest.
