The alias support was dead code since 2011. It was last touched
in r124182, where it was reintroduced after being removed
in r110434, and since then it was gated behind a HasGlobalAliases
flag that was permanently stuck as `false`.
It is also broken. I'm not sure if it bitrotted or was just broken
in the first place because it appears to have never been tested,
but the following IR results in a crash:
define internal i32 @a(i32 %a, i32 %b) unnamed_addr {
%c = add i32 %a, %b
%d = xor i32 %a, %c
ret i32 %c
}
define internal i32 @b(i32 %a, i32 %b) unnamed_addr {
%c = add i32 %a, %b
%d = xor i32 %a, %c
ret i32 %c
}
It seems safe to remove buggy untested code that no one cared about
for seven years.
