__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...
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...

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 Constraints...
gcc 、 g++分别是gnu的c & c++编译器 。实际上,GCC 能够编译三种语言:C、C++ 和 Object C(C 语言的一种面向对象扩展)。 GCC: the GNU Compiler Collection GNU 编译器集合包括 C、C++、Objective-C、Fortran、Ada、Go 和 D 的前端,以及这些语言的库(libstdc++,...)。 GCC 最初是作为 GNU 操作系统的编...

使用带有gcc的SSE指令而不使用内联汇编是指在使用GNU编译器集成开发环境(GCC)进行编程时,利用SSE(Streaming SIMD Extensions)指令集进行并行计算,而不使用内联汇编。 SSE是一种SIMD(单指令多数据流)指令集,它可以在一个指令周期内对多个数据进行相同的操作,从而提高计算效率。在编程中,可以使用内联汇编或者GCC内置函数...
