<pre>In the below, clang should not output junk. gcc does not.
$ cat tgc.c
#include <stdio.h>
int main() {
return 0;
}
void junk() {
printf("");
}
$ clang -ffunction-sections -fdata-sections -Wl,--gc-sections tgc.c; llvm-nm
a.out | grep junk
0000000000000120 T junk
[$ gcc -ffunction-sections -fdata-sections -Wl,--gc-sections tgc.c; nm a.out |
grep junk
$
This is 6.0.1 from the release branch from the monorepo using a custom port.
Should reproduce I think on any non-darwin port.</pre>
