<div>
<pre>Compiling this program (with wasm32-wasi for stdio.h, but the bug isn't
specific to WASI):
#include <stdio.h>
__attribute__((export_name("yellow")))
static void green(void) {
printf("hello green, exported as yellow\n");
}
int main(void) {
return 0;
}
produces an executable which doesn't export "yellow".
I expected this to mean that the C symbol "green" is internal, so it can't be
directly linked to from other C files, but that it's treated as live through
the linker and exported from the resulting wasm module as "yellow". Is that
reasonable?</pre>
