PR middle-end/50040
* gimplify.c (gimplify_modify_expr_complex_part): Mark the
load of the other piece with TREE_NO_WARNING.
* tree-flow.h (warn_uninit): Adjust prototype.
* tree-ssa.c (warn_uninit): Take uninitialized SSA name,
the base variable and the expression that is used separately.
Properly query all TREE_NO_WARNING flags.
(struct walk_data): Remove.
(warn_uninitialized_var): Likewise.
(warn_uninitialized_vars): Do not walk gimple pieces but simply
look at all SSA uses of the statement. Handle unused memory
separately.
* tree-ssa-uninit.c (warn_uninitialized_phi): Adjust.
* g++.dg/warn/unit-1.C: Un-XFAIL.
* gcc.dg/uninit-I.c: Likewise.
