DMD now has a 64-bit codegen that works quite well (well enough for serious use, no showstopper bugs) on Linux. This has been around since 2.052, released last February. It also supports 64-bit on FreeBSD, though I don't know how well that works because I've never tried it. On Windows and Mac OS, 64-bit isn't supported. On Windows this is because Optlink (the linker DMD uses on Windows) doesn't work with 64-bit objects. On Mac OS, I don't know what the bottleneck is. GDC has also been improving rapidly and is, as far as I can tell, one showstopper bug (https://bitbucket.org/goshawk/gdc/issue/226/gc-from-spawned-threads-segfaults-on-64) away from being usable for serious work on Linux x64. It already seems usable in 32-bit mode. There's been some work towards porting it to Windows, but that's somewhat behind the curve. The Windows version only supports an ancient front-end release and 64-bit Windows support is buggy. LDC is a release behind DMD and GDC, so I haven't been following it. It's supposed to support 64-bit Linux, though.
