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!

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:

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.

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.

If I not mistaken next version would be 1.0?

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).

Great job and impressive bugfix list.
Could someone please update
