@noinline ignored

[damiendr]

It looks like Julia 0.6 ignores @noinline in the following snippet:

@noinline bar() = 1
function foo()
    bar()
end
@code_typed(foo())

The pure+constant return logic bypasses noinline...

[damiendr]

OK, good to know. I was using noinline functions like these as a tag for introspection purposes, but I will find another way if that's the new logic.

Won't this cause problems with #265 ?

[yuyichao]

This is unrelated to #265.

Is this still the case? I am trying to implement a macro similar to how @noinline is supposed to work, but I'm no sure the code that arrives at emit_function in codegen.cpp really has the structure expected by jl_has_meta. I cannot make my macro work, and I guess it could be the same issue.

If @noinline is still supposed to be propagated to LLVM then this would depend on #27104
