N3639 C++1y VLA support
gcc/
* gimplify.c (gimplify_vla_decl): Don't touch an existing
DECL_VALUE_EXPR.
gcc/cp/
* decl.c (compute_array_index_type): Allow VLAs in C++1y mode.
(check_array_initializer): Allow VLA init.
(reshape_init_array_1): Adjust.
(cp_finish_decl): Check for invalid VLA length.
* typeck2.c (process_init_constructor_array): Adjust.
(store_init_value): Use build_vec_init for VLAs.
* semantics.c (add_capture): Capture VLA as ptr+len.
(vla_capture_type): New.
(build_capture_proxy): Rebuild the VLA.
* typeck.c (build_simple_component_ref): Split out from...
(build_ptrmemfunc_access_expr): ...here.
* tree.c (array_of_runtime_bound_p): New.
* init.c (throw_bad_array_length): New.
(build_vec_init): Use it.
* parser.c (cp_convert_range_for): When iterating over a VLA,
use it directly rather than bind a reference.
* cp-tree.h: Declare new functions.
libstdc++-v3/
* libsupc++/new: Add std::bad_array_length.
* libsupc++/bad_array_length.cc: New.
