digitalmars.D.learn - Inline Assembler: Getting the offset of a label. How?

Hello d folk,

I have a question about D 1.0 inline asm. Has anyone an idea how to get
the offset of a label without using "call Label1", then "pop eax".
Actually there would be an offsetof but it seems not to work.

In other (inline) assemblers I'd just use offset or addr, but it seems
that my Win32 DMD 1.037 does not understand it.

I'd be really helpful for any solution, because I need it to write
position independend code. Thanks.

regards, pimp

mov eax, Label1

Hi Kagamin,

I've just tried this piece of Code:

[snip]
	asm
	{
		call Label1;
		Label1: pop ECX;
		mov EAX, Label1; //error reported on this line
	}
[/snip]

And I still got an error like: "undefined identifier 'Label1'".

Do you have maybe another solution or know whats wrong here? Thanks.

regards, the pimp

I tried several tricks, seems like compiler doesn't support this.
