> If Zig code doesn’t look like it’s jumping away to call a function, then it isn’t.

I'll admit, I don't know zig. But how would it implement 1.0*2.0 for an architecture that doesn't support float multiplication? I assume that it would do something like compiler-rt and replace that operation with a function call. See https://github.com/llvm/llvm-project/tree/main/compiler-rt/l... for examples of "code that doesn't look like a function call" that actually is.
