Debug

The debug operations do not map to any compiler intrinsics for MMX(TM) instructions. They are provided for debugging programs only. Use of these operations may result in loss of performance, so you should not use them outside of debugging.

Output

cout << Is32vec4 A;

cout << Iu32vec4 A;

cout << hex << Iu32vec4 A; /* print in hex format */

The four 32-bit values of A are placed in the output buffer and printed in the following format (default in decimal):

"[3]:A3 [2]:A2 [1]:A1 [0]:A0"

Corresponding Intrinsics: none

cout << Is32vec2 A;

cout << Iu32vec2 A;

cout << hex << Iu32vec2 A; /* print in hex format */

The two 32-bit values of A are placed in the output buffer and printed in the following format (default in decimal):

"[1]:A1 [0]:A0"

Corresponding Intrinsics: none

cout << Is16vec8 A;

cout << Iu16vec8 A;

cout << hex << Iu16vec8 A; /* print in hex format */

The eight 16-bit values of A are placed in the output buffer and printed in the following format (default in decimal):

"[7]:A7 [6]:A6 [5]:A5 [4]:A4 [3]:A3 [2]:A2 [1]:A1 [0]:A0"

Corresponding Intrinsics: none

cout << Is16vec4 A;

cout << Iu16vec4 A;

cout << hex << Iu16vec4 A; /* print in hex format */

The four 16-bit values of A are placed in the output buffer and printed in the following format (default in decimal):

"[3]:A3 [2]:A2 [1]:A1 [0]:A0"

Corresponding Intrinsics: none

cout << Is8vec16 A; cout << Iu8vec16 A; cout << hex << Iu8vec8 A;

/* print in hex format instead of decimal*/

The sixteen 8-bit values of A are placed in the output buffer and printed in the following format (default is decimal):

"[15]:A15 [14]:A14 [13]:A13 [12]:A12 [11]:A11 [10]:A10 [9]:A9 [8]:A8 [7]:A7 [6]:A6 [5]:A5 [4]:A4 [3]:A3 [2]:A2 [1]:A1 [0]:A0"

Corresponding Intrinsics: none

cout << Is8vec8 A; cout << Iu8vec8 A;cout << hex << Iu8vec8 A;

/* print in hex format instead of decimal*/

The eight 8-bit values of A are placed in the output buffer and printed in the following format (default is decimal):

"[7]:A7 [6]:A6 [5]:A5 [4]:A4 [3]:A3 [2]:A2 [1]:A1 [0]:A0"

Element Access Operators

int R = Is64vec2 A[i];

unsigned int R = Iu64vec2 A[i];

int R = Is32vec4 A[i];

unsigned int R = Iu32vec4 A[i];

int R = Is32vec2 A[i];

unsigned int R = Iu32vec2 A[i];

short R = Is16vec8 A[i];

unsigned short R = Iu16vec8 A[i];

short R = Is16vec4 A[i];

unsigned short R = Iu16vec4 A[i];

signed char R = Is8vec16 A[i];

unsigned char R = Iu8vec16 A[i];

signed char R = Is8vec8 A[i];

unsigned char R = Iu8vec8 A[i];

Access and read element i of A. If DEBUG is enabled and the user tries to access an element outside of A, a diagnostic message is printed and the program aborts.

Corresponding Intrinsics: none

Element Assignment Operators

Is64vec2 A[i] = int R;

Is32vec4 A[i] = int R;

Iu32vec4 A[i] = unsigned int R;

Is32vec2 A[i] = int R;

Iu32vec2 A[i] = unsigned int R;

Is16vec8 A[i] = short R;

Iu16vec8 A[i] = unsigned short R;

Is16vec4 A[i] = short R;

Iu16vec4 A[i] = unsigned short R;

Is8vec16 A[i] = signed char R;

Iu8vec16 A[i] = unsigned char R;

Is8vec8 A[i] = signed char R;

Iu8vec8 A[i] = unsigned char R;

Assign R to element i of A. If DEBUG is enabled and the user tries to assign a value to an element outside of A, a diagnostic message is printed and the program aborts.

Corresponding Intrinsics: none
