Hi everyone!

On behalf of the LDC team I am proud to announce the LDC 0.16.0 beta2 release!
It is based on the 2.067.1 front-end and LLVM 3.1-3.7 (OS X: no support for 3.3).

If no more severe errors are reported then the next version will be the final release. The LDC team already considers this the best LDC release of all times!

Big news is that the Win64 version of the compiler reaches production quality, thanks to the hard work from kinke!

This release has been checked to work on Linux/PPC64 and OpenSolaris (x86), too. There is still a major issue on FreeBSD (x86_64) (issue #1119).
Due to a library build problem with druntime/Phobos there is no MinGW32 version (issue #1121). This is currently under investigation but we are also looking for volunteers. If you need this platform please consider helping us!!!

Big thanks to everyone who provided feedback on the last beta version! Without your feedback it would not be possible to eliminate the bugs so fast!

Most important changes are:

- Frontend is now at 2.067.1
- LLVM 3.7 is supported
- DMD-style coverage analysis is added
- ABI changes which fixes a lot of bugs in the Win64 compiler
- The ldc2 driver now only use slow -debuglib libraries if explicitly asked to

Be sure to read the change log at the GitHub release page which also has the package download links:

Regarding the binaries:
The Linux binaries are built on Ubuntu 12.04 LTS with gcc 4.8.x and LLVM 3.7.0. They work on Ubuntu 12.04 LTS (or later) without installing additional software.

The OS X binaries are built with LLVM 3.6.2 on OS X 10.10.

The Win64 MSVC version is built with VS2015 using LLVM 3.7 in release mode. The distribution now contains a precompiled libcurl 7.40.0 from http://d.darktech.org/libcurl.html. For any other VisualStudio version you need to rebuild the library.
You find the build script here: https://github.com/ldc-developers/ldc-scripts/blob/master/ldc2-win64/RELEASE.proj

Please be sure to report any bugs at https://github.com/ldc-developers/ldc/issues, and feel free to drop by at the digitalmars.D.ldc forums (http://forum.dlang.org/group/digitalmars.D.ldc) for any questions or comments.

Thanks to everybody involved in making this happen!

Regards,
Kai

Fantastic, thanks! (I filed one minor issue, otherwise looks great!)

Hello, I have some issues with align() attribute.
http://pastebin.com/1uCRwDfS
Assert fails if I uncomment somefun(buf) line but works otherwise.
win64 msvc build
ldc2 main.d -w -g -unittest -m64 -oq

Hmm,

I see in the IR

  %_param_0 = alloca %bug.some_buf*, align 8      ; [#uses = 2, size/byte = 8]

which is consistent with the output. :-(

Kai

I have a vibe.d project linking to some C++ code and

dub build --compiler=/tmp/ldc2-0.16.0-beta2-linux-x86_64/bin/ldc2 --force

prints

warning: Linking two modules of different data layouts: '<string>' is '' whereas 'source/myfile.d' is 'e-m:e-i64:64-f80:128-n8:16:32:64-S128'

C++ compiler is
g++ (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4

Any guess where this comes from? A hint would help create a reduced test case / find my mistake. A similar (but smaller project) compiles fine...

dub clean does not help.

The produced binary seems to work.

I was of the impression that you need to put the initialized field of a union first, but maybe I'm wrong. There is at least this in the documentation on struct literals: "If there are anonymous unions in the struct, only the first member of the anonymous union can be initialized with a struct literal, and all subsequent non-overlapping fields are default initialized." It may or may not apply here.
