* gengtype.c (write_field_root): Avoid out-of-scope access of newv.
* tree-stdarg.c (execute_optimize_stdarg): Accept clobbers.
* tree.h (TREE_CLOBBER_P): New macro.
* gimple.h (gimple_clobber_p): New inline function.
* gimplify.c (gimplify_bind_expr): Add clobbers for all variables
that go out of scope and live in memory.
* tree-ssa-operands.c (get_expr_operands): Transfer volatility also
for constructors.
* cfgexpand.c (decl_to_stack_part): New static variable.
(add_stack_var): Allocate it, and remember mapping.
(fini_vars_expansion): Deallocate it.
(stack_var_conflict_p): Add early outs.
(visit_op, visit_conflict, add_scope_conflicts_1,
add_scope_conflicts): New static functions.
(expand_used_vars_for_block): Don't call add_stack_var_conflict, tidy.
(expand_used_vars): Add scope conflicts.
(expand_gimple_stmt_1): Expand clobbers to nothing.
(expand_debug_expr): Ditto.
* tree-pretty-print.c (dump_generic_node): Dump clobbers nicely.
* tree-ssa-live.c (remove_unused_locals): Remove clobbers that
refer to otherwise unused locals.
* tree-sra.c (build_accesses_from_assign): Ignore clobbers.
* tree-ssa-dce.c (mark_stmt_if_obviously_necessary): Clobbers of
SSA names aren't necessary.
(propagate_necessity): Accept and ignore constructors on the rhs,
tidy.
* gimple.c (walk_gimple_op): Accept constructors like mem_rhs.
* tree-ssa-structalias.c (find_func_aliases): Clobbers don't store
any known value.
* tree-ssa-sccvn.c (vn_reference_lookup_3): Ditto, in particular they
don't zero-initialize something.
* tree-ssa-phiopt.c (cond_if_else_store_replacement_1): Ignore
clobber RHS, we don't want PHI nodes with those.
testsuite/
* gcc.dg/tree-ssa/20031015-1.c: Adjust.
* g++.dg/tree-ssa/ehcleanup-1.C: Ditto.
* g++.dg/eh/builtin1.C: Rewrite to not use local variables.
* g++.dg/eh/builtin2.C: Ditto.
* g++.dg/eh/builtin3.C: Ditto.
