Description bearophile_hugs 2013-07-31 14:33:02 UTC 
import std.math;
import core.simd: double2;
void main() {
    double2 x;
    double2 y = x ^^ 2;
    double2 z = x ^^ 3;
}


Gives errors like:

test.d:5: Error: template std.math.pow does not match any function template declaration
.../math.d:3180: Error: template std.math.pow cannot deduce template function from argument types !()(__vector(double[2LU]),__vector(double[2LU]))


Similar errors are generated by ldc2 on Windows32.

SIMD ^^ is neither generic, nor a trivial thing to implement.

We should really just flat out error here.
Comment 2 Walter Bright 2020-12-22 05:31:03 UTC 
Now it errs with the messages:

test.d(6): Error: incompatible types for (x) ^^ (cast(__vector(double[2]))2.0): both operands are of type __vector(double[2])
test.d(7): Error: incompatible types for (x) ^^ (cast(__vector(double[2]))3.0): both operands are of type __vector(double[2])

which is adequate.
