digitalmars.D.ldc - LDC 1.1.0 released

Hi everyone,

On behalf of the LDC team I am happy to finally announce the 
release of LDC 1.1.0, based on the 2.071. It has been in the 
making for an uncharacteristically long time, but we hope you 
will enjoy the multitude of new features: profile-guided 
optimization, better-integrated link-time optimization, 
experimental cross module inlining and first Windows DLL export 
support; along with UDAs for fine-grained optimizer control (e.g. 
 fastmath), a partial object file cache, and of course many other 
bug fixes and improvements.

Binary packages (now also including Dub) and the source tarball 
can be found on the GitHub release page, along with the detailed 
changelog:

https://github.com/ldc-developers/ldc/releases/tag/v1.1.0

All the binary packages are built against LLVM 3.9.1. The Linux 
x86/x86_64 binaries are built on Ubuntu 12.04 LTS and should work 
on any newer distribution. The Win32 and Win64 MSVC versions are 
built with Visual Studio 2015, and shouldn't be expected to work 
with any older version.

Note that there were some changes to the command line semantics, 
which – although mostly minute – could break some application: 
http://forum.dlang.org/post/ubobkfmsspbsmjunosna forum.dlang.org

Please be sure to report any bugs at 
https://github.com/ldc-developers/ldc/issues, and feel free to 
post here in the digitalmars.D.ldc forums for any questions or 
comments.

Oh, and stay tuned for a new release soon, now that the LDC 
release process has been straightened out and the team has more 
manpower again. There even is a pull request open for 2.072.2 
already.

Just added armhf binary (arm-none-linux-gnueabihf) built on Raspbian
GNU/Linux 8.0 (jessie).  It can run on both armv7 and armv6 systems
(Raspberry Pi 2,3 are armv7, original Pi 1 and Pi Zero are armv6).  I've
only tested it on Raspbian, hopefully it will work on other ARM boards
running a compatible Linux version.

Congratulations everyone! :-)

I've uploaded an updated version of the snap package to the 
Ubuntu store, based on the following package definition:
https://github.com/ldc-developers/ldc2.snap/releases/tag/rev2

As before this is now awaiting manual review, which based on 
previous experience should take a few working days.  I'll make a 
post in the Announce forum once it is published.

The snap package uses LLVM 3.8, since there's not a 3.9 package 
available in Ubuntu 16.04.  I'm looking into how to most 
effectively get 3.9 in there; it will probably involve building 
LLVM from source, but since that's a reasonably hefty process, I 
thought I'd get an initial v1.1.0 snap out there before moving on 
that.

It's now published in the `edge` channel.  For people with it 
already installed, `sudo snap refresh` (or `sudo snap refresh 
--edge ldc2` if that doesn't work) should upgrade it for you.  
Otherwise,

     sudo snap install --classic --edge ldc2

... should install it on an Ubuntu 16.04 system or later.

A colleague gave it a go on his Arch machine, and it seems that 
the `snapd` version available there still doesn't support classic 
snaps.  If anyone is running Debian, Gentoo, Fedora or OpenSUSE, 
it would be great to know about your experience -- you can 
install `snapd` following the instructions here: 
https://snapcraft.io/docs/core/install

This has now been updated:
https://github.com/ldc-developers/ldc2.snap/releases/tag/rev3

The new package uses a fresh build of LLVM 3.9.1 as the backend, 
as well as bootstrapping with a fresh build of LDC 0.17.3.

Thanks to Johan's advice I've also enabled LTO support.  This is 
definitely an experimental feature -- I'm not 100% sure the 
package's LLVMgold-ldc.so plugin will work on systems that do not 
have ABI compatibility with Ubuntu 16.04 -- but since the package 
is still in the (bleeding) 'edge' channel, I thought it was worth 
trying out ;-)

Let me know if you try it out and it works (or fails!) for you!

Thanks & best wishes,

I am using Lubuntu 16.10, testing a simple hello world:

This is actually a bug in the binary package, which I just added 
an issue for: https://github.com/ldc-developers/ldc/issues/2008

Ubuntu 16.10 unfortunately broke forwards-compatibility for 
libraries and compilers, in the sense that they patched the 
linker to create position-independent executables by default. We 
decided to follow suit and make LDC default to 
position-independent code on Linux as well (which makes sense as 
it enables ASLR and friends). Thus, setting 
`-relocation-model=pic` doesn't change anything – as indicated in 
the error message, the problem is in the C parts of the standard 
library, not your D code.

This is because the packages are built on an older Ubuntu 
version, with the default C compiler settings – which of course 
implicitly default to non-PIC. We'll have to amend our build 
scripts and push out a new point release to fix this. I'm rather 
amazed that during six (!) beta versions, nobody tested the 
binaries on 16.10…

(DMD 2.071.2 and older was completely broken on 16.10 for this 
reason.)

Ah, thanks for the detailed reply. Funny that I downloaded the 
beta version for testing exactly this, but couldn't thanks to my 
new born daughter :)
Looking forward to the next point release with the fix.

Since you're on Ubuntu 16.10 you could also try the snap package 
for LDC 1.1.0:

     sudo snap install --classic --edge ldc2

Done, installed OK.

Executed it and it failed with exact same error, which I guess is 
expected:

I wasn't expecting it to fail, as I'd had a previous report of it 
working OK on 16.10. :-\

I presume that part of the improvements for classic snaps you mentioned 
was building on an older system where GCC doesn't default to 
position-independent code – try v1.1.1-beta1, which includes 
https://github.com/ldc-developers/ldc/pull/2009.

Can confirm it works on 14.04.  I verified also with 16.10 last 
night, but can re-verify this evening if you want extra

Sai, if you are happy to try this out, it would be good to have

I am not sure how to download the prebuilt from GitHub, I am not 
good at navigating the GitHub pages yet. I already verified the 
snap, if you can give me a link to the pre-built on Github, I 
will download and test it on my PC.

Thank you (and David) for fixing this very promptly.

Just a stupid question:  Which one is preferred as a user? Snap 
version or the prebuilt version on Github? Personally I don't 
mind as long as the download/install instructions are clear. But 
It seems to me that snap is supposed to be more user friendly. So 
may be snaps are preferred for non-experts like me?

I don't think the GitHub prebuilt 1.1.1 packages are available 
yet.  You can check the list of releases (and corresponding

David did all the fixes, I just tested them out to make sure they 
worked ;-)

It's not at all a stupid question.

The easy answer is, "Whichever you prefer as a user."  The 
slightly more complicated answer is that the snap packages are 
quite a recent effort which is still somewhat work-in-progress.  
The current snap package is in the --edge snap channel (as in, 
'bleeding edge') for a reason. ;-)

However, in practice, as an Ubuntu user, it is likely to be just 
as effective for you, and certainly easier to install and keep up 
to date.  So if that works nicely for you, there's no reason you 
shouldn't continue to use it.

If you do that, though, I'd suggest keeping an eye out for 
announcements related to the snap package, since its status may 
change fairly often in the near future.  You can also report any 
compilation problems you encounter here:

I had the old ldc installed from apt-get on the path. I 
uninstalled it now and added /snap/bin to the path. I know I

Oh, and `snap info` doesn't need `sudo` in order to work.  You 
can run it as a regular user.

It's only when you are doing things like install/remove that you
