Hi,
I'm writing a high level interpreter (Windows, but eventually others) in FASM and would like to be able to invoke FASM as a DLL from the interpreter for inline assembly. Nothing fancy--even something as simple as sending the DLL a single line (without unresolved variables) and getting the assembly code back.
Anyone done anything like this, or could anyone give hints as to how to proceed?
Thanks,
Glenn Dixon

wouldn't it be better statically linked? is there any reason to use DLL?

Thanks for your reply.
The interpreter is a language itself and you can write executable code in it.

Something like Forth. Inline assembly would be used to write routines that need to be either time or space efficient. They generally would be very short and simple subroutines, and you would write and execute them "on-the-fly" without compiling the entire application again.

Thanks,
Glenn

yes, but i mean you can compile FASM into linkable file and then link it into your executable. you don't need another file (FASM.DLL).

dixong, I think this is a nice idea. It could be very useful for learning fasm in classroom style environment. Also useful to have fasm as scripting option at runtime in game or whatever project.

One can make GUI for it to assist the learner execute the fasm code he/she wrote on the spot. It's bring back the memory of using DBase or Foxpro. It does help to speed up the learning process.

The other benefits is the DLL being used as FASM framework. Located far away at a server computer and call-able by client PC thats connected to the servers. Something like an Enterprise version of FASM runtime DLL.

I wonder if this can be done, later-on, has anyone thought of making an ActiveX or COM version of FASM DLL?

i.e. in HLL (basic) calls:

Code:

MyObj.QueryInterface(IID_FASM, @lpFasm)
lpFasm.Execute(@MyAsmString) 'MyAsmString contain multiple 
                             'lines of inline FASM codes
lpFasm.Release

I think a DLL version for FASM would be great!
I agree with i-don!

Unless you need an immediate binary return of the line assembled (don't forget FASM is multi-pass), why don't you simply use redirection and launch it as a child process?

That's actually how Reva currently integrates assembly... it uses FASM in precisely that manner if desired.

Or you can simply generate a FASM output and call FASM like this:

FASM.EXE "~ABCDEF~.TMP" "ABCDEF.EXE"

I also have heard that FASM can produce *.OBJ files, I'm not sure about that one though as I have never needed to use a *.OBJ in an assembly-language project (operating system) before.

There is actually a FASM dll library, it is attached in the Windows section thread of "fasm.dll" or something from about a week or so ago. Should work great if this poject is still going lol.
