Hi everyone!

On behalf of the LDC team I announce the new 1.2.0-beta1 release!
It is based on the 2.072.2 front-end and supports LLVM 3.5-4.0.

Beside the new front-end there are some more fixes to increase robustness of the compiler. Be sure to read the change log at the GitHub release page for details. The packages are available for download at the same page.
https://github.com/ldc-developers/ldc/releases/tag/v1.2.0-beta1

MD5 checksums for the release packages:

Regarding the binaries:
The Linux x86/x86_64 binaries are built on Ubuntu 12.04 LTS with gcc 4.8.x, ldc2 1.2.0-beta1 and LLVM 4.0.0. They work on Ubuntu 12.04 LTS (or later) without installing additional software.

The OS X binaries and the FreeBSD binaries are built with LLVM 4.0.0.

The Win32 and Win64 MSVC versions are built with VS2015 and LLVM 3.9.1 (due to a regression in LLVM 4.0).

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

Great to see this coming so fast!  Btw, OS X is now called macOS.

Well, we still support pre-Sierra, so _technically_… ;)

kinke has been working hard on it, and.... LDC master is at 2.073 already!

I tested a bit 1.2.0-beta1 as a cross compiler for ARM. Good news is that basic stuff like "hello world" works. Really good news, at least for me, is that all this was done on Windows Linux Subsystem [1].

Unfortunately all good news ends as soon I try something more involved, like:
=======================================
import std.stdio;

void main()
{
    try
    {
      throw new Exception("darn!");
    }
    catch(Exception e)
    {
      writeln(e.msg);
    }
    writeln("Hello world!");
}
=======================================
I get:

Fatal error in EH code: _Unwind_RaiseException failed with reason code: 9
Aborted

The machine I'm running this on is an ARM926EJ-S rev 5, and the ABI used is ARM, EABI5 version 1 soft float.

Any idea what might be wrong here?

Thanks for testing. Joakim also encountered this error during his ARM tests, see https://github.com/ldc-developers/ldc/issues/2024.

I have no problem when either cross-compiling or natively compiling that code for Android/ARM, by using the llvm triple armv7-none-linux-android with ldc 1.2.  What llvm triple are you using?

It could be that the ARM exception-handling code isn't right for your ARM platform/ABI, as we had similar issues on other ARM platforms till Dan fixed them:

I tried a couple of things

ldc2 -mtriple=arm-none-linux-gnueabi -gcc=arm-linux-gnueabi-gcc


Then something closer to my config

ldc2 -mtriple=armv4t-none-linux-gnueabi -mcpu=arm9tdmi -gcc=arm-linux-gnueabi-gcc

The problem I think is that the system I'm targeting uses ARM, EABI4 version 1 (SYSV), as bellow:

readelf -A libc-2.9.so
Attribute Section: aeabi
File Attributes
  Tag_CPU_name: "ARM9TDMI"
  Tag_CPU_arch: v4T
  Tag_ARM_ISA_use: Yes
  Tag_ABI_PCS_wchar_t: 4
  Tag_ABI_FP_denormal: Needed
  Tag_ABI_FP_exceptions: Needed
  Tag_ABI_FP_number_model: IEEE 754
  Tag_ABI_align_needed: 8-byte
  Tag_ABI_align_preserved: 8-byte, except leaf SP
  Tag_ABI_enum_size: int

But the app I build uses ARM, EABI5 version 1 (SYSV)

Attribute Section: aeabi
File Attributes
  Tag_CPU_name: "5T"
  Tag_CPU_arch: v5T
  Tag_ARM_ISA_use: Yes
  Tag_THUMB_ISA_use: Thumb-1
  Tag_ABI_PCS_GOT_use: GOT-indirect
  Tag_ABI_PCS_wchar_t: 4
  Tag_ABI_FP_rounding: Needed
  Tag_ABI_FP_denormal: Needed
  Tag_ABI_FP_exceptions: Needed
  Tag_ABI_FP_number_model: IEEE 754
  Tag_ABI_align_needed: 8-byte
  Tag_ABI_enum_size: int
  Tag_CPU_unaligned_access: v6
  Tag_ABI_FP_16bit_format: IEEE 754

Did a small test in C++ using the gcc cross compiler and exceptions are working with the same ABI and cpu name and arch as the ones I got with ldc. So eabi version is not an issue here.

OK, looking up that CPU now, it's an old ARMv5 core, whereas we've tested on ARMv6 at best.  If you want to use ldc for that, you may need to help port ldc/druntime to those older embedded cores.
