Re: NEW asm.dlang.org site
Thanks for the good work! It would be really nice if in the future we could compare DMD, GDC and LDC (and SDC when it becomes more usable) at asm.dlang.org. (Btw a nice choice of name :) ) I have a couple of questions about the output when looking at a C++[1] program and the same in GDC[2] and DMD[3](I am not very familiar with assembly): 1) Syntax: AFAIU, (_D)main pushes 3 and 4 to the stack and calls (example.)add. Then (example.)add loads them from the stack in two registers and adds them. IIRC, dmd passes parameters in reverse order (of the normal C way) and that's why pushing and loading 3 and 4 from the stack is in reverse order. However why does DMD use hex instead of decimal notation? [I was also a little confused about positive vs negative indexing of bp and the order of src and dst in the arguments to movl, but then I noticed that I am comparing x86 and x86_64, so I managed to answer those questions myself :D ] 2) _Dmain: I also noticed that the output of gdc-4.4 and gdc-4.6 does not include a label for _Dmain (nor the regular C main). Is this a problem of the disassembly, or just how older version of GDC produced code?

Re: DlangUI
Was pleasantly surprised to see that it worked without having to manually muck with any dependencies. Resource usage is minimal, interface feels smooth (though obviously ugly, but that isn't the point). I can't wait until I have some extra free time to build something with this and hopefully contribute. Great work! P.S. I noticed that it *almost* builds with gdc, but fails on freetype. Have you been attempting to target gdc at all for those performance gains?

Whereas with DMD I had to disassemble from object code (using obbjdump). This is an implementation detail really of how DMD works vs GCC backend. 2) _Dmain: I also noticed that the output of gdc-4.4 and gdc-4.6 does not include a label for _Dmain (nor the regular C main). Is this a problem of the disassembly, or just how older version of GDC produced code? GCC-Explorer thinks _Dmain is a label, and sees that it is unused (not called from anywhere). So it removes it. In later versions of GDC, a C main function is included in the compilation, and so now references _Dmain. I guess this is a bug in GCC Explorer itself that will need to be addressed somehow. Iain.

I tried the demo but I get an error: SDL_GL_CreateContext failed: Failed creating OpenGL context Running Mac OS 10.10.2 on 2011 Macbook Pro Never tried it on mac. I believe, if OpenGL context cannot be created, DlangUI SDL backend should switch to bare SDL (sw renderer). I would rather expect that app crashes on missing fonts. Linux (and mac) font paths are hardcoded. Where are .ttf files located on macos? Fast and dirty fix is possible - add paths for a few mac fonts. Could you please share startup logs? As well, you can try to build w/o OpenGL - clone repository and remove USE_OPENGL version from dub.json

So, not horrible, but could also be a whole lot less (down from 1k to 74 based on January's data) if it were cached on each host.
