Thanks for this post. Please also consider creating a Wiki page as that's more easily accessible for posterity (and editable) than a forum post here.

I think he also has done some other things besides Dconf. Hope to see you there! -Steve

So is the executable linked to an installed instance of LDC/LLVM to make this happen, or is there some limited compiler embedded in the executable or Druntime? More details about the implementation please. Mike Jit runtime (ldc-jit.dll/so) uses llvm optimizer and backend. Forgot to mention, user need to pass `-enable-dynamic-compile` compiler switch to enable this feature (and jit runtime will only be linked in this case).

New LDC feature: dynamic compilation
Main part of this feature is a new UDA `@dynamicCompile`.
You can mark with this attribute any function (including class
methods and lambdas) and compilation and optimization of this
function will be deferred to runtime.
Dynamic compiler will use instruction set available on host, so
application can utilize the best available instructions without
sacrificing users with old hardware.
You only need to mark top-level function with this UDA, compiler
will also defer compilation for any function called from root
with body available.
You need to explicitly compile `@dynamicCompile` functions before
using any of them.
CompilerSettings settings;
settings.optLevel = 3; // -O3
compileDynamicCode(settings); // compile all dynamic functions
Second feature is `@dynamicCompileConst` variables.
You can mark any global non-thread local variable with this
attribute.
They are treated as usual from static code but if they are
treated as compile-time constants by optimizer when accessed from
`@dynamicCompile` function.
Example:
`@dynamicCompileConst` __gshared simdSize;
`@dynamicCompile` void foo()
{
if (4 == simdSize)
{
// SSE-otimized code
}
else if (8 == simdSize)
{
// AVX-optimized code
}
}
...
simdSize = 4;
compileDynamicCode();
Optimizer will treat `simdSize` as constant and remove checks and
not taken branches.
You shouldn't change these variables from dynamic code (this is
UB and will probaly crash you)
And you need to recompile dynamic code with
`compileDynamicCode(...)` if you want changes to these variables
take effect in dynamic code.
These are highly experimental features so expect major bugs.
Known issues:
* There is debug hook to get final asm generated for
`@dynamicCompile` function but it is disabled now (but you can
still get original and optimized LLVM IR for them)
* Exceptions doesn't work on windows if there are dynamic
functions in stack (they work on linux and osx).
* There are codegen issues on win32, use win64
Munich D Meetup November 2017
Hi all, Tomorrow November 14th, we will have our next Munich meetup. This time Seb and Stefan will give an introductory talk about templates and CTFE.

Presumably that's why whoever was compiling those FreeBSD builds stopped bothering. Fair enough. 4 is better than 0 though. And, you never know, that could have been 4 large enterprises ;-) (plenty of large enterprise use FreeBSD). Now it's getting no downloads at all.

Hi everyone,
on behalf of the LDC team, I'm glad to announce the first beta
for LDC 1.6. The highlights of this version in a nutshell:
* Based on D 2.076.1.
* Experimental support for dynamic codegen at runtime ('manual
JIT').
* Many std.math functions are now CTFE-able.
Full release log and downloads:

Thanks to all contributors!
Fast update, thank you!
There is no version for FreeBSD?

The new mechanism of operation with memory is realized that allowed will get rid of crash of applications in case of completion. The summary code amount increases all the time. New classes from Qt are added. Now the code amount reached: qte5.d - 6700 lines qte5widgets.cpp - 3500 lines The considerable efforts are made in development of bitmap graphics, QBitmap, QResource, QPixmap are added and properties for QImage are added.
