__int128: 128-bit integers—__int128. Not implemented. Long Long: Double-word integers—long long int. Implemented in C and C++. Complex: Data types for complex numbers. untyped _Complex defaults to double for compatibility with gcc. Implemented in C only. Floating Types: Additional Floating...
Since the ABI requires a function returning a 128-bit integer to do so in %rax and %rdx, the above has no extra register to register copies. (Other than that required to get the multiply instruction initialized.)X86 Floating Point ConstraintsThe x86 has a strange floating-point coprocessor w...
GCC now supports Power ISA 2.07, which includes support for Hardware Transactional Memory (HTM), Quadword atomics and several VMX and VSX additions, including Crypto, 64-bit integer, 128-bit integer and decimal integer operations. Support for the POWER8 processor is now available through the-mcpu...

By default, such a bit-field is signed, because this is consistent: the basic integer types such as "int" are signed types. Options Controlling C++ Dialect This section describes the command-line options that are only meaningful for C++ programs. You can also use most of the GNU compiler ...
该issue 记录 rpm-tracker 抓取数据,每日判断是否有满足条件的 commit,若有则追加到评论。 开发者首先判断是否有需要合入的 commit,若有则评论/pick命令,流水线会修改 ocs-commit/repo 仓库。 若合入失败,开发者可直接修改 ocs-commit/repo 仓库,通过/recheck命令重新触发检查。
