From d7789889b1839c3c0f64c6738b0d8517ccead049 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 31 Jan 2023 10:57:20 -0500 Subject: gdbsupport: allow passing nullptr to checked_static_cast Both static_cast and dynamic_cast handle nullptr (they return nullptr), so I think checked_static_cast should too. This will allow doing a null check after a checked_static_cast: cooked_index_vector *table = (gdb::checked_static_cast (per_bfd->index_table.get ())); if (table != nullptr) return; Change-Id: If5c3134e63696f8e417c87b5f3901240c9f7ea97 --- gdbsupport/gdb-checked-static-cast.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'gdbsupport') diff --git a/gdbsupport/gdb-checked-static-cast.h b/gdbsupport/gdb-checked-static-cast.h index cc298733fad..bc75244bddd 100644 --- a/gdbsupport/gdb-checked-static-cast.h +++ b/gdbsupport/gdb-checked-static-cast.h @@ -54,6 +54,9 @@ checked_static_cast (V *v) "types must be related"); #ifdef DEVELOPMENT + if (v == nullptr) + return nullptr; + T result = dynamic_cast (v); gdb_assert (result != nullptr); #else -- cgit v1.2.1
