The debug operations do not map to any compiler intrinsics for MMX™ technology or Intel® Streaming SIMD Extensions . 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.
The two single, double-precision floating-point values of A are placed in the output buffer and printed in decimal format as follows:
cout
<< F64vec2 A;
"[1]:A1
[0]:A0"
Corresponding
intrinsics: none
The four, single-precision floating-point values of A are placed in the output buffer and printed in decimal format as follows:
cout
<< F32vec4 A;
"[3]:A3 [2]:A2
[1]:A1 [0]:A0"
Corresponding intrinsics: none
The lowest, single-precision floating-point value of A is placed in the output buffer and printed.
cout
<< F32vec1 A;
Corresponding intrinsics: none
double d = F64vec2 A[int i]
Read one of the two, double-precision floating-point values of A without modifying the corresponding floating-point value. Permitted values of i are 0 and 1. For example:
If DEBUG is enabled and i is not one of the permitted values (0 or 1), a diagnostic message is printed and the program aborts.
double d =
F64vec2 A[1];
Corresponding intrinsics: none
Read one of the four, single-precision floating-point values of A without modifying the corresponding floating point value. Permitted values of i are 0, 1, 2, and 3. For example:
float f = F32vec4 A[int i]
If DEBUG is enabled and i is not one of the permitted values (0-3), a diagnostic message is printed and the program aborts.
float f =
F32vec4 A[2];
Corresponding intrinsics: none
F64vec4 A[int i] = double d;
Modify one of the two, double-precision floating-point values of A. Permitted values of int i are 0 and 1. For example:
F32vec4
A[1] = double d;
F32vec4 A[int i] = float f;
Modify one of the four, single-precision floating-point values of A. Permitted values of int i are 0, 1, 2, and 3. For example:
If DEBUG is enabled and int i is not one of the permitted values (0-3), a diagnostic message is printed and the program aborts.
F32vec4
A[3] = float f;
Corresponding intrinsics: none.
