I would guess LDC supports it as long as LLVM does.

BTW, after the next version of macOS, High Sierra, Apple will drop the support for 32bit applications. You need to move to 64bit.

For a C implementation that doesn't support TLS, using it in D with -betterC won't work.

I won't miss it.

I don't think it'll be long before 32 bits starts disappearing from Windows and Linux as well.

As a pragmatic matter, the D community doesn't have the resources to support systems that have been abandoned by their vendors. This is why D officially doesn't support Windows XP anymore.

Good move from Apple.
I distribute both bitness as Universal Binaries, most probably this will still work.

For ldc users on linux, 32-bit x86 compiler downloads are basically a rounding error:

http://www.somsubhra.com/github-release-stats/?username=ldc-developers&repository=ldc

ldc 1.1.0 was released with a native linux/ARM build also, the stats in that link show it was downloaded almost 30 times more than the linux/x86 build.

We should generate the default string from the expression for D too. (at a minimum, I'd actually like to see every variable printed out too, but this is already written)

I keep meaning to write an update to that post because there have been a lot of improvements to the ecosystem since then.  (I've been kind of busy the past few months.)

Those strings eat up space and are of pretty marginal utility. Don't want to make assert's so bloatsome that people are discouraged from using them.

nope, they aren't. but they are immediately helpful. i integrated such patch to my dmd ages ago, and i'm not speaking out of nothing -- they *are* helful.

and i can't see how *adding* *useful* *info* to assertion will discourage people from using 'em.

"bloatsome"? i don't think so. those generated messages is small (usually 20-30 bytes), and nothing comparing to druntime/phobos size.
