#include<stdio.h>
inline void test(char const* str) noexcept
{
    puts(str);
}

int main()
{
    test("Hello\n");
}

hello.cc
module;
#include<stdio.h>
export module hello;

export inline void test(char const* str) noexcept
{
    puts(str);
}


main.cc
import hello;

int main()
{
    test("Hello\n");
}


The 2nd generates a larger binary because it emits dead module entry.

Please remove all dead code thank you.
