Chapter 3.11, Problem 3.51PP

Explanation of Solution

Table for code sequences:

• The details of table are shown below:

Tx	Ty	Instructions
long	double	vcvtsi2sdq %rdi, %xmm0, %xmm0
double	int	vcvttsd2si %xmm0, %eax
float	double	vunpcklpd %xmm0, %xmm0, %xmm0 vcvtpd2ps %xmm0, %xmm0
long	float	vcvtsi2ssq %rdi, %xmm0, %xmm0
float	long	vcvttss2siq %xmm0, %rax

Explanation:

• The argument “x” is either in “%xmm0” or in named portion of register “%rdi”.
• The assembly instructions are used to perform type conversion and to copy value to named portion of register “%rax”...
