Hi everyone!

On behalf of the LDC team I am proud to announce the LDC 0.15.2 beta1 release!
It is based on the 2.066.1 front-end and LLVM 3.1-3.6 (OS X: no support for 3.3).

This minor release fixes some issues. Most important are the ABI changes which fixes a lot of bugs in the Win64 compiler.

Be sure to read the preliminary change log at the GitHub release page which also has the package download links:
https://github.com/ldc-developers/ldc/releases/tag/v0.15.2-beta1

Regarding the binaries:
The Linux binaries are built on Ubuntu 12.04 LTS with gcc 4.8.x and LLVM 3.6. They work on Ubuntu 12.04 LTS (or later) without installing additional software.

As always, the Win32/MinGW packages require a recent version of the mingw-w64 toolchain, see http://wiki.dlang.org/Building_LDC_on_MinGW_x86 for details. The package is build with i686-4.9.1-release-posix-dwarf-rt_v3-rev1 downloaded with the mingw installer.

The Win64 MSVC version is still considered alpha quality. It is built with VS2013 using LLVM 3.6 in release mode.
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

I've got release-0.15.2 and LLVM 3.6 working with iOS and no regressions.

The ABI change presented me with an interesting puzzle though.  It switched extern (D) varargs to C style varags pushed on the stack instead of a separate arg array.

I had been using fastcc function calls [1] for extern (D) on IOS due to an LLVM optimizer bug with C calling convention (ccc) and, for a lesser reason, because the fastcc assembly code can at times be beautiful compared to ccc on iOS.  But fastcc doesn't support C style varags.

The path of least resistance seemed to be adopting ccc function calls. The LLVM optimizer bug with ccc still caused a unittest failure with LLVM 3.5.1.  Updating to LLVM 3.6 though apparently fixed it.

I am using that mingw release. If I swap ldc2 v.0.15.1 with v.0.15.2-beta1, I receive the errors:

...>ldmd2 test.d
Error: ...:\MinGW\lib\gcc failed with status: -1
Error: message: Couldn't execute program 'C:\MinGW\lib\gcc'Access denied.

Do you have suggestions?

Bye,

Hi bearophile!

I don't see a reason why the gcc file in the lib folder should be called. In my installation, this is a file with 0 byte size. The gcc exe lives in the bin folder.
Is your PATH variable reasonable set? Did you set the CC variable?

Kai
