Oh, I'm quite familiar with why Walter chose the boost license, and I agree with that choice (I use it for all of my projects). My point was that it doesn't seem to be a very common choice outside of the D community (at least from what I've seen). - Jonathan M Davis

Could someone give this licensing neophyte an explanation and some history? So dmd's backend came directly from dmc. This makes sense as this is the time of Digital Mars creation (Walter has been working with this code base pretty much since before I was born). Because of how history went, it was owned by Symantic yet Digital Mars still developed it. So its usage within dmd caused problems, i.e. with packaging and distributing because it required explicit permission from Digital Mars so that Symantic wouldn't get sued. Maybe Walter can clarify but this is what I have gathered over the years.

There's also the aspect, AIUI, that Walter has refrained from looking at / contributing to the code for any other compiler backend, in order to avoid legal complications arising from possible "tainting" from the dmd backend code. E.g., if he were to submit a patch to the gcc backend, Symantec could in theory come back and sue the gcc guys claiming that their code is based on the dmc backend and so they have to pay royalties. Or if he were to read the code for gcc's backend, Symantec could in theory accuse him of incorporating GPL code into the dmc backend (since he's still working on the backend every now and then), which is incompatible with the license. Of course, IANAL so this relicensing may not necessarily imply that Walter is now free to read / work on other compiler backends. Nor does he necessarily want to do so anyway. But regardless, this is a major step forward at least in the aspect of finally putting to rest the "D is non-free" FUD that's been spreading around over the years. T -- Bare foot: (n.)

LDC supports both DMD-style asm {} blocks as well as LLVM's native inline assembly format, which is very similar to GCC's, with explicit clobber specifications and explicit parameter passing (https://wiki.dlang.org/LDC_inline_assembly_expressions). The latter is useful on non-x86 platforms as well as to allow more optimizations of functions using inline asm such as inlining (although inlining in particular can also be enabled for DMD-style asm blocks using a pragma). There are also inline IR expressions for the few situations where you don't want to drop down all the way to inline assembly but still need to crack open the hood and control the emitted LLVM IR: https://wiki.dlang.org/LDC_inline_IR. For example, we use it to implement some target-independent SIMD intrinsics in the library. — David

GDC wrote the work-alike x86 assembler, and later dual-licensed it to share with LDC. A little while later I dropped it from GDC as it was not really fit for purpose, and rather outside the scope of what I see should be handled at the language level in the compiler.

Thanks for clarifying. I did not know that history.

Good news! Thank you! I gave a hint of this - additionally mentioning Dconf - to heise.de, with success: Programmiersprache D: Referenzcompiler DMD unter freier Lizenz https://www.heise.de/newsticker/meldung/Programmiersprache-D-Referenzcompiler-DMD-unter-freier-Lizenz-3678894.html I propose that the D Language Foundation releases an official press release about the new situation and send it to all important it/computer magazines. May be we can talk about pr strategy for D in general at Dconf. Regards mt.

Does this mean that we can now embed the D compiler in to a commercial D app to be used as a scripting like engine(D app compiles D code then dynamically links in code while running)?

As a compiler-writer no-nothing, does this have any implications on the various back-ends gaining ideas/code from each other? That is, is it possible we see LDC compile times go down, or DMD optimizations get better? I hope you tell the story of how this came about at Dconf :) -Steve

You can't change the license or copyright on the code, i.e. you can't transmit code from DMD to LDC and change the license of it. And LDC code cannot be transmitted to DMD and have its license changed. So whether this is possible or not depends. If the LDC license is more restrictive than Boost, then DMD cannot incorporate that code.
