从 C7000 编译器 v3.0 开始，C7000 TI 编译器 (cl7x) 接受构造函数样式的语法来进行向量初始化。若要创建使用 cl7x 和主机仿真进行编译的可移植代码，请对向量初始化使用构造函数样式语法，而不是仅适用于 cl7x 的“cast/scalar-widening”初始化样式。

以下代码中显示了正确和错误的向量构造函数初始化语法示例。

/* Host Emulation vector constructor syntax examples */
// The following examples work for both cl7x and Host Emulation
long2 ex1 = long2(1);                  // -> (1,1)
long2 ex2 = long2(1,2);                // -> (1,2)
long8 ex3 = long8(long4(1), long4(2)); // -> (1,1,1,1,2,2,2,2)
long8 ex4 = long8(long4(1),2,3,4,5);   // -> (1,1,1,1,2,3,4,5)

// Do not use the following syntax for code that needs to compile 
// with Host Emulation. This is valid C++ syntax, but results are 
// not as expected when compiling with Host Emulation.
//long8 ex5 = (long8)(1,2,3,4,5,6,7,8); // -> (8,8,8,8,8,8,8,8) [for Host Emulation]
