Any other backend would be better. DMD with -O takes over an

2-3 different compilers when D is already lacking manpower.
A 60:1 speedup? I've never heard of that big of a difference
before. Especially since LDC is typically slower to compile,
even on massive code bases like Weka's.
Could you please file a bug with some details?
I ran it again, was a bit over a minute. But still 1 min 30
seconds compared to an hour.
1:07:40.162314 -- dmd with -O
0:01:28.632916 -- ldc2 with -O
0:00:23.802639 -- dmd without -O
0:00:33.818080 -- ldc2 without -O
It'd be quite a bit of work to narrow down what it is and if it
has something to do with how many structures I use or otherwise.
I'd have to try and emulate that with test code as I can't use my
code. Then the issue would just sit there for who knows how long.
It's not that big of an issue, as I just use ldc2 instead anyways.
