gengtype.c (write_field_root): Avoid out-of-scope access of newv.
* 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.
