Moral of the story is, if you're writing a compiler, for the

any source code, I want the hashes of the binaries to be
identical every single time. DMD doesn't do this and it
saddens me greatly.
DMD doesn't? What does it do that isn't deterministic?
I have no idea. As a simple test, I compiled one my source files
to an object file, and ran md5sum on it. I did this again and the
md5sum is different. Looking at a diff of the hexdump isn't very
fruitful either (for me at least). For reference, I'm on Linux
x86_64 with DMD v2.071.0.
