* emit-rtl.c (copy_most_rtx): Accept EXPR_LIST for may_share.
* function.c (fixup_var_refs): Add MAY_SHARE parameter.
(fixup_var_refs_insns, fixup_var_refs_insns_with_has): Likewise.
(fixup_var_refs_insn, fixup_var_refs_1): Likewise.
(pop_function_context): Compute MAY_SHARE parameter for
fixup_var_refs.
(fixup_var_refs_1, case MEM): Pass MAY_SHARE to copy_most_rtx, not VAR.
(gen_mem_addressof): Call fixup_var_refs with new parm.
