Could someone clarify why the generated assembly for
void main() @nogc {

enum a = [3, 1, 2, 0]; // inferred to be int[]
enum b = sort(a);
static assert(b[0] == 0);

is 1380 lines with ldc 1.3.0 (-O3 -release -betterC -flto=full)?
You can see the result on godbolt here:

It's kind of surprising compared to C++'s 2 lines:

_Dmain is exactly 2 instructions, so nope equivalent :)
The linker isn't stripping out unused symbols however (from what I can
tell).
I see. Is there any argument that can be passed to ldc in order to strip
the unused symbols?
Should be a way, since you can pass arg directly via ldc to ld. But I
would expect it to have done it by default anyway.
