+Subject: [PATCH] media::learning: Make LabelledExample's move assignment
+ operator noexcept
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The GCC build is currently broken with an error like this:
+
+    ../../media/learning/common/labelled_example.cc:20:1: error: function ‘media::learning::LabelledExample::LabelledExample(media::learning::LabelledExample&&)’ defaulted on its redeclaration with an exception-specification that differs from the implicit exception-specification ‘’
+     LabelledExample::LabelledExample(LabelledExample&& rhs) noexcept = default;
+     ^~~~~~~~~~~~~~~
+
+With GCC, having that noexcept marker requires all members to be marked with
+noexcept themselves, and TargetValue was missing some assignment operators
+and noexcept markers.
+
+clang is fine because we pass -fno-exceptions and it disables the same error
+there, while GCC continues to raise it (bug 843143 and its corresponding CL
+have a longer discussion on this issue).

+Subject: [PATCH] color_utils: Use std::sqrt() instead of std::sqrtf()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This fixes the build with libstdc++:
+
+    ../../ui/gfx/color_utils.cc: In function ‘SkColor color_utils::SetDarkestColorForTesting(SkColor)’:
+    ../../ui/gfx/color_utils.cc:434:12: error: ‘sqrtf’ is not a member of ‘std’
+           std::sqrtf((dark_luminance + 0.05f) * (kWhiteLuminance + 0.05f)) - 0.05f;
+                ^~~~~
+    ../../ui/gfx/color_utils.cc:434:12: note: suggested alternative: ‘sqrt’
+           std::sqrtf((dark_luminance + 0.05f) * (kWhiteLuminance + 0.05f)) - 0.05f;
+                ^~~~~
+                sqrt
+
+sqrtf() is not formally part of C++14 as far as I can see even though libc++
+has it in <cmath>. Additionally, we're only dealing with floats in all parts
+of the expression above, so using the float sqrt() overload should be
+harmless anyway.

+Due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84849, having
+base::NoDestructor<T<U>> and passing an initializer list of Us does not
+work if this is not done explicitly, as GCC incorrectly fails to determine
+which constructor overload to use:

+Subject: [PATCH] BaseRenderingContext2D: Use base::CheckMul and simplify code
+ in putImageData()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Follow-up to commit e0b3253a56 ("Fix image conversion truncation issues").
+The current code does not build with GCC due to
+https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89287:
+
+    ../../third_party/blink/renderer/modules/canvas/canvas2d/base_rendering_context_2d.cc: In member function ‘void blink::BaseRenderingContext2D::putImageData(blink::ImageData*, int, int, int, int, int, int, blink::ExceptionState&)’:
+    ../../third_party/blink/renderer/modules/canvas/canvas2d/base_rendering_context_2d.cc:1777:44: error: default type conversion can't deduce template argument for ‘template<class Dst, typename std::enable_if<base::internal::IsNumericRangeContained<Dst, long unsigned int, void>::value, void>::type* <anonymous> > constexpr base::internal::StrictNumeric<T>::operator Dst() const [with Dst = Dst; typename std::enable_if<base::internal::IsNumericRangeContained<Dst, T>::value>::type* <anonymous> = <enumerator>; T = long unsigned int]’
+             new uint8_t[data_length.ValueOrDie()]);
+                                                ^
+
+Work around it by using the more idiomatic base::CheckMul() with
+AssignIfValid, so that we can have |data_length| be a size_t again and not
+leave it to the compiler to figure out the type we want when creating the
+|converted_pixels| array.

+Subject: [PATCH] CastActivityManager: Do not make DoLaunchSessionParams' move
+ constructor noexcept
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This fixes the GCC build:
+
+    ../../chrome/browser/media/router/providers/cast/cast_activity_manager.cc:806:1: error: function ‘media_router::CastActivityManager::DoLaunchSessionParams::DoLaunchSessionParams(media_router::CastActivityManager::DoLaunchSessionParams&&)’ defaulted on its redeclaration with an exception-specification that differs from the implicit exception-specification ‘’
+     CastActivityManager::DoLaunchSessionParams::DoLaunchSessionParams(
+     ^~~~~~~~~~~~~~~~~~~
+
+With GCC, having that noexcept marker requires all members to be marked with
+noexcept themselves, and MediaRoute, CastMediaSource and url::Origin need
+the right annotations. Just making DoLaunchSessionParams not noexcept is the
+least intrusive solution for now.
+
+clang is fine because we pass -fno-exceptions and it disables the same error
+there, while GCC continues to raise it (bug 843143 and its corresponding CL
+have a longer discussion on this issue).
