Hi everyone!

The LDC team moves fast to a major milestone: we're aiming for a 
1.0.0 release!

On behalf of the LDC team I am proud to announce the new 
1.0.0-alpha1 release!
It is based on the 2.069.2 front-end and supports LLVM 3.5-3.8.

This is the first ALPHA version of the release. The main purpose 
is to find the remaining bug. Thus please help testing!

The Travis-CI shows all green but there are still issues left:

- The build system does not use a D compiler for linking. This 
can result in link failures due to missing libraries.
- LDC on Win64 is not yet able to compile itself.
- A bug with vararg handling in version 0.17.0 prevents linking 
of LDC on ARM
- Other architectures and operating systems must be still 
evaluated

Again, we need to help to test this alpha release! Every feedback 
is welcomed!

Be sure to read the change log at the GitHub release page which 
also has the package download links:
https://github.com/ldc-developers/ldc/releases/tag/v1.0.0-alpha1

cea6d778edc4464397e93770ce5952e8 ldc2-1.0.0-alpha1-win64-msvc.zip

Regarding the binaries:
The Linux binaries are built on Ubuntu 12.04 LTS with gcc 4.8.x, 
ldc2 0.17.0 and LLVM 3.7.1. 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 (update 1) using dmd 
2.069.2 and LLVM 3.7.1 in release mode. The distribution now 
contains a precompiled libcurl 7.46.0 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

The OS X binaries are actually built on OS X 10.11, with the 
MACOSX_DEPLOYMENT_TARGET being set to 10.7. The latter is new 
(previously it was not being set at all) and should fix linker warnings 
when using the pre-built binaries on earlier OS versions.

Thanks, nice to have the warnings disappear. The 1.0 alpha works 
fine on my simple test programs on both Mac OSX and Linux 
(64-bit).

Hi Guillaume

it just means that I did not take the extra effort to integrate 
the ALPHA Win32 code into the ALPHA version of the release. First 
we need to make the bootstrap process smooth before integrating 
more stuff. But nice to see the interest in the compiler!

Kai

This is an excellent news, finally a fairly recent front-end with 
decent optimization!
The alpha works great so far for all my projects.

BTW I was pleased to notice that LDC produces the smallest 
binaries of all D compilers, especially when templates are in 
heavy use.

Well, it isn't pretty but can pass the dmd testsuite for objc.  I'll
organize it a litte better, get a pull going to show work in progress.

That was quick :). Please let me know when you have a pull request 
available, I can help with the code review.

Would be inserting to enable all tests in objc_objc_msgSend.d and see if 
they work in LDC.

I uncommented lines in main (I think that is what you mean) to this:

void main()
{
    test_stret();
    test_fp2ret();
    test_fpret();
    test_float32();
    test_double64();
}

And it works.  I was unsure if the fp2ret and C++/D complex types would
work, but for this test they do.

Some code has already been converted to D (out of necessity / 
ease of transitioning to DDMD). At least for code that does not 
interface with LLVM, it'd be nice to convert it to D (imho).

I made https://github.com/ldc-developers/ldc/pull/1325 from my hack
session last saturday. It is no where close, but at least you can see a
start. Maybe we can make a branch in LDC repo for this so you and others
can collaborate?

Yes, I'd say let's just create a branch in ldc-developers/ldc.

It takes me a lot to understand what's wrong in a parser code.
I finally reduced code to this:

size_t inc(size_t* v)
{
    (*v)++;
    return 10;
}

size_t pos = 10;
	
immutable tst = pos + inc(&pos); // <-- this
writeln(tst);
writeln(pos);

The marked line was an unintended mistake inside original code.
Anyway it gives different result with dmd and ldc2 1.0. I neither 
know if is a undefined behaviour.

I hope LDC computes tst = 20. ;)
Iirc, there were some inconsistencies wrt. this. LDC and GDC do 
it one way (the proper one imo), dmd another way.

"Proper" depends on specs. If is an undefined behaviour i think 
it should be defined or a warning should be triggered

Spec:
https://dlang.org/spec/expression.html#order-of-evaluation

Strict left-to-right order evaluation, as the spec prescribes, 
would give tst=20.
Is there a DMD bug report for this? I didn't test with DMD, but 
if tst!=20, it is a pretty severe issue.

Dmd gives 20. Ldc gives 21:

Great news! I've tried the latest alpha on most of my projects - 
works like a charm on Linux64. :)
On Windows there is still that nasty library extension naming 
issue with dub.. however, that should be fixed with dub 0.9.25.
