4Subject: [PATCH] Added support for extending operations to GCC atomic backend.
5
6Fix for #10446. Some platforms (e.g. Raspberry Pi) only support atomic ops of some particular size but not less. Use extending arithmetic operations for these platforms. Also, make sure bools are always treated as 8-bit values, even if the actual type is larger. This makes its use in atomic<>, atomic_flag and lock pool more consistent.
