Hi,

After a much needed rebuild of the server running various 
GDC-related hosted services 
[http://forum.dlang.org/post/zrnqcfhvyhlfjajtqebt forum.dlang.org] - I've
gotten round to updating the compiler disassembler.

http://explore.dgnu.org/

Now supports 12 different architectures from ARM to SystemZ! (not 
including -m32 or any -march options)

Enjoy.
Iain.

This is awesome, I think I am going to use this to finally learn 
some assembly. But I am not quite sure though what the output is, 
is it x86 or x64?

The first is x64. You can switch to x86 using -m32.  However I 
could just add an extra compiler to do this automatically.

Done.  Also made the target names more clear.

Nice, is there a _best_ resource to understand the parameters, e.g. what is
(%rip) after a symbol name?

Not sure of any precise resource.  However this explains the need 
for %rip

Nice!
Is there a way to override the default '-Og'? It seems that now 
Currently I cannot see any difference

BTW, dunno how it's now, but about a year ago GDC was able to 
compile for AVR after removing two asserts in the frontend 
(checking if the pointer size is at least 32 bits or the like).

Oops, pressed "Send" too quickly.
Should be: I cannot see any difference in the output when I enter 
various optimization options.

Ah, I left that test option in by accident.  Removed.  :-)

The situation should be exactly the same.  You may notice that 
not all targets hosted are able to compile 
std.stdio.writeln("Hello World").  I hope that giving awareness 
that these exist will help finish off the druntime ports for 
these platforms.

I was sad that the 68k version doesn't work. :(

On an unrelated note, is is normal for write() to cause so much 
more ASM than writeln()?  IIRC, writeln() just wraps write(), so 
it seems strange that the latter would generate an order of 
magnitude more code than the former (looks like most of it is 
unicode exception stuff).

If you want, you can get cracking with porting the library to it.

This seems to be the reason why.

Raise a patch to do the same for write() too?  Removing the "\n" 
in fprintf of course.

I noticed that Intel ASM syntax no longer worked with supported 
compilers. This has been fixed.
