Yes, this pair of types is not supported. Generally, I only add type pairs to builtins if they are present in Go's stdlib — and there's no function that returns (float32, float32) there.

You can use two separate calls (there's no benefit to combining them anyway) or declare a custom return type.

@nalgeon actually the go math package has a Sincos function but solod's math package does not implement it. https://pkg.go.dev/math#Sincos

[BrownNPC]

Also if solod does not support this combo it shouldnt generate code that expects so_R_f32_f32 dont you think?

[nalgeon]

Maybe, but not at this stage. I'd rather not complicate the compiler with such checks for now.
