| |
From: Li Zefan <lizf@cn.fujitsu.com>
Currently TP_fast_assign has a limitation that we can't define local variables in it.
Here's one use case when we introduce __dynamic_array():
TP_fast_assign( type *p = __get_dynamic_array(item);
foo(p); bar(p); ),
[ Impact: allow defining local variables in TP_fast_assign ]
