* trans.h (gfor_fndecl_internal_realloc): Declare.
(gfor_fndecl_internal_realloc64): Declare.
* trans-decl.c (gfor_fndecl_internal_realloc): New variable.
(gfor_fndecl_internal_realloc64): New variable.
(gfc_build_builtin_function_decls): Initialize them.
* trans-array.h (gfc_trans_allocate_temp_array): Add a fourth argument.
* trans-array.c (gfc_trans_allocate_array_storage): Add an argument
to say whether the array can grow later. Don't allocate the array
on the stack if so. Don't call malloc for zero-sized arrays.
(gfc_trans_allocate_temp_array): Add a similar argument here.
Pass it along to gfc_trans_allocate_array_storage.
(gfc_get_iteration_count, gfc_grow_array): New functions.
(gfc_iterator_has_dynamic_bounds): New function.
(gfc_get_array_constructor_element_size): New function.
(gfc_get_array_constructor_size): New function.
(gfc_trans_array_ctor_element): Replace pointer argument with
a descriptor tree.
(gfc_trans_array_constructor_subarray): Likewise. Take an extra
argument to say whether the variable-sized part of the constructor
must be allocated using realloc. Grow the array when this
argument is true.
(gfc_trans_array_constructor_value): Likewise.
(gfc_get_array_cons_size): Delete.
(gfc_trans_array_constructor): If the loop bound has not been set,
split the allocation into a static part and a dynamic part. Set
loop->to to the bounds for static part before allocating the
temporary. Adjust call to gfc_trans_array_constructor_value.
(gfc_conv_loop_setup): Allow any constructor to determine the
loop bounds. Check whether the constructor has a dynamic size
and prefer to use something else if so. Expect the loop bound
to be set later. Adjust call to gfc_trans_allocate_temp_array.
* trans-expr.c (gfc_conv_function_call): Adjust another call here.
