Hi everyone,

LDC 1.4.0 is out now. The highlights of version 1.4 in a nutshell:

* Based on D 2.074.1.
* Shipping with ldc-build-runtime, a small D tool to easily (cross-)compile the runtime libraries yourself.
* Full Android support, incl. emulated TLS.
* Improved support for AddressSanitizer and libFuzzer. The libraries are shipped with the prebuilt Linux x86_64 and OSX packages.
* Prebuilt Linux x86_64 package shipping with LTO plugin, catching up with the OSX package.
* Prebuilt packages include the NVPTX LLVM target, in order to target CUDA via DCompute.

Full release log and downloads: https://github.com/ldc-developers/ldc/releases/tag/v1.4.0

Thanks to everybody contributing!

Thanks. Why is the executable named `ldc2` on Linux? If it's for historical reasons, why not just drop it and use just `ldc`?

I agree, it was probably done to differentiate with D 1.0 back in the day, but enough time has passed since D 1.0's demise that we can probably just switch, while keeping a ldc2 symbolic link or wrapper so as not to break any code.

Because we can't simply change it and thus break integration with build tools.

Yep that is/was the reason. Symbolic file links on Windows are very uncommon, as they require an NTFS file system and Vista or newer.

A hard link should be fine for a file.
https://msdn.microsoft.com/en-us/library/windows/desktop/aa363860%28v=vs.85%29.aspx docs say hard links were supported on xp.

Or, worst case, we could even provide a tiny binary that simply forwards to ldc, as ldmd2 currently does after adjusting for ldc's flags.

Requires NTFS too, only supported on the same volume (can't just move/copy to another partition), and the targets are apparently fixed (no relative link targets) after a quick test (copying to other directory). So I don't see an alternative to ugly wrappers for Windows compatibility.

Erm, yeah, by definition as hard link. ;) As we don't have an installer on Windows, just a portable archive, hard links aren't an option.

I would expect them to be in the same folder. The downside for hardlink can be deletion and recreation of one of the files, after which they become unrelated files.

I have updated the wiki page on building ldc from source, showing how to build our branch of llvm and switching it to CMake:

https://wiki.dlang.org/Building_LDC_from_source

I have also added some info about building on or for Android.  Please look it over and add anything I missed.

I will now remove the instructions on building ldc for Android here, since it's all in the official page now and no patches are needed:
