Hi everyone,

LDC 0.16.0, the LLVM-based D compiler, is available for download!
This release is based on the 2.067.1 frontend and standard library and supports LLVM 3.1-3.7 (OS X: no support for 3.3).

Don't miss to check if your preferred system is supported by this release. We also have a Win64 compiler available!

As usual, you can find links to the changelog and the binary packages over at digitalmars.D.ldc:

Regards,
Kai

Congratulations!

Has anyone on the LDC team done any benchmarks on how much faster ddmd is when compiled with LDC?

ldc was recently added to the list of compilers that test ddmd continuously on travis CI:

https://github.com/D-Programming-Language/dmd/pull/5025

The associated travis CI run that finally went green with ldc 0.16.0 beta 2 took about as long as the other D compilers, so performance of ldc-compiled ddmd seems comparable:

If I not mistaken next version would be 1.0?

That's surprising given that many were worried that switching to ddmd would slow compilation speeds down by at least 30%. Also, this does not seem to be using any of ldc's optimization flags.

Next version will be 0.17 (based on 2.068 frontend still written in C++). But the next after next version will be 1.0 (based on 2.069 which includes the frontend written in D).

Well, all three of those are ddmd: the only difference is whether ddmd is compiled by dmd, gdc, or ldc.  The 30% measurement was based on comparing the previously completely C++ dmd with ddmd:

Whoops, posted before I was done writing.

The Travis CI run combines the time spent compiling ddmd, time spent compiling the druntime/phobos tests, and then running the tests.  The original 30% comparison was only for time spent compiling a D codebase, like phobos or vibe.d.

It's possible ldc takes longer to compile ddmd, but then the resulting ddmd takes less time to compile phobos.  That would have to be separated out.  It's also possible the backend is not the issue and the D frontend itself is slower than the C++ frontend, in which case using ldc to compile ddmd won't make a difference.

Great job and impressive bugfix list.
Could someone please update https://ldc-developers.github.io/LATEST.
