Glad to announce D 2.075.0.

This release comes with various phobos additions, a repackaged
std.datetime, configurable Fiber stack guard pages (now also on
Posix), and optional precise GC scanning for the DATA/TLS segment (static
data) on Windows.

Wow, dmd builds in 12 seconds on a single linux/x64 core, can't wait to see what that time is when the backend is in D too, especially since it's taking most of the compile time now.

Thanks to those involved for all the work on the release.

The sticking point there is the base D compiler used by GDC and LDC needs to be upgraded with the -mv switch.

Pretty dazz! Thank you!

Congratulations Martin and everyone!

A snap package for DMD 2.075.0 is now available in the `edge` channel of the snap store:

    sudo snap install --classic --edge dmd

for a fresh install, or

    sudo snap refresh --classic --edge dmd

... for anyone who already has an earlier version installed.

Note that there's a known issue with `rdmd` in this package (which is an issue with `snapd` rather than the package itself).  However, please do let me know about any other issues (or successes!).

version 2.067 that still had the C++ frontend took more than 100 seconds. I think if the backend is translated to D, building the compiler will take not more than 2 seconds.
To put it in perspective, building gcc with only C and C++ support takes around 15 minutes on my machine and clang+llvm is ridiculously slow to compile with not far from 1 hour compilation.
Ok, these projects are much, much bigger but that doesn't change the fact that C++ is slow to compile.

DMC++ takes about 15 seconds to do an optimized build of itself on my old Windows XP machine. (Of course, it doesn't use STL, or any templates for that matter. The code predates templates.)

One day, a colleague and I were working on migrating a large MSVC project to LLVM. Due to various reasons (using git master / bisecting regressions), this involved building LLVM from source code, which took an exorbitant amount of time (about 40 minutes IIRC).

Later that day, I mentioned in passing that we might make building D part of the build process (of a project using D code), since building the compiler took only 3 seconds on my machine.

To quote my colleague:

"Whaaaaaaaaaaat? How can a compiler compile in 3 seconds?!"

I can hardly believe it. I remember versions 2.05x building in about 11 seconds.

wow, how nice - but it is not installed correctly with VS2017. While installing, i am told that 64bit will not work.

what a SH.T

you guys should get your act together - just once. it's always a real experience to install software and have problems. Nice experience!!
