Subject: [PATCH] GCC: make base::{flat_map,flat_tree} move assignement operators noexcept
|
|
|
|
Move assigment operator in ui::ColorSet is noexcept. Because this
|
|
class has a member of type base::flat_map, move assignment operators
|
|
of base::flat_map and base::flat_tree must be noexcept too.
|
|
base::flat_tree noexcept is conditional to avoid build failure with
|
|
NaCl.
|
|
|
|
Otherwise GCC fails like this:
|
|
|
|
../../ui/color/color_set.cc:14:11: error: function
|
|
'ui::ColorSet& ui::ColorSet::operator=(ui::ColorSet&&)' defaulted on its
|
|
redeclaration with an exception-specification that differs from the
|
|
implicit exception-specification ''
|
|
14 | ColorSet& ColorSet::operator=(ColorSet&&) noexcept = default;
|
|
| ^~~~~~~~
