Test case: --- import core.simd; pure @safe V1 simd(XMM opcode, V1, V2)(V1 op1, V2 op2, ubyte imm8) if (is(V1 == __vector) && is(V2 == __vector)) { return cast(V1)__simd(opcode, op1, op2, imm8); } void main() { float4 a, b; a = simd!(XMM.CMPPD)(a, b, 0x7A); }

https://github.com/dlang/dmd/pull/7216 The imm8 needs to go into the template parameter list as a constant.

Seems like a strange limitation, but it's your intrinsic.
