How would I go about forcing the compiler to not optimize out a function, an have it only be evaluated at runtime? I am currently doing so by passing arguments that can only be evaluated at runtime like pointers, but that is not ideal.

to make sure the function isnt' being run at comptime add this to the start of the function body
if(@inComptime()) @compileError("");
to make sure the compiler isn't optimizing the call out, maybe wrap the call like this: std.mem.doNotOptimizeAway(someFn());

Lets say my function returns a u32, how would I get the return value when wrapping th function in std.mem.doNotOptimizeAway?

const x = someFn();
std.mem.doNotOptimizeAway(x):
thanks! Will try!
