Now available in the Download section.

This is mainly the cleanup release (read more here). Also a more detailed note about "eqtype" operator has been added to documentation - it was the last important feature that has not yet been documented enough.

Since now all further development goes into direction of version capable of generating AMD64 long mode code - in future releases X86.INC is going to be replaced with new file, containing the long mode support.

?Hi Privalov,
In file win32ax.inc (and also win32wx.inc), the macro "allow_nesting" contains :-

purge _invoke %_ }

I think it has to be :-

purge invoke %_ }

hasn't it?

cheers,
Q

Hello.

I wrote this code:

Code:

format ELF

section '.text' executable

     public _start
       _start:
 nop

and trying to compile with the FASM v1.56, but occurs such error:

Quote:

public _start
error: undefined symbol.

But FASM v1.55 successfull compile this code.

What I made wrong?
Or it's new feature, which are not well documented at the FASM help?

Besr regards,
IceStudent

Yes, you right.

All versions of compiler, which I have (1.50..1.56), compile such code.
But builds with the listing support are can not compile it.

First of all, at v1.56 changed size of variable org_origin: dq,
so I must change the code at listing.inc:

Code:

 mov     dword [adjustment],eax
      mov     dword [adjustment+4],eax
    mov     dword[org_origin],edi         ; <-- changed 
     mov     dword[org_origin+4],eax    ; <--

I think, it's correct..

Then I observed, that problem is here:

Code:

    cmp     [listing_file],0
    je      no_line_pointers_needed
         ....
      no_line_pointers_needed:
;     dec     [current_pass]                ; <-- you must comment this line
   ret

If I comment this line, FASM successfully compile all examples of the Linux version (and even FASM source): with the listing option or no.

Of course, may be I made mistake, so tell me about it.

Best regards,
IceStudent

Yeah, the listing feature has not been adapted to the latest changes of internals yet.

Another small update has been made today, with a small fix made as a side-effect during writing the internals documentation. In the mean time I have also updated the 64-bit division algorithm used by expression evaluator, as it happened to be terribly slow in some cases of dividing two very large values.

The today's fix can be the most simply described on a small example:

Code:

a equ b
b equ 1
a: mov eax,a

The bug that existed in preprocessor caused the "a" label to be preprocessed twice, so the whole line was becoming "1: mov eax,b" (and causing an error), while it should be "b: mov eax,b", as it is done by the updated 1.56.

Hi, Privalov!

Just another suggestion from me (maybe not so useless for anyone but me). Are you planning to extend string operations functionality so we could write e.g. such piece of code:

Code:

macro display_a_to_b _str {
  local ..str
  ..str = ''
  repeat length(_str)
    if _str[%] = 'a'
      ..str = ..str + 'b'
    else
      ..str = ..str + _str[%]
    end if
  end repeat
  display ..str,13,10
}

With this little extension we could even make something like PRINTF macro. What do you think?

I've forgotten to check that (you know of course what EQTYPE does).

yes, but anyway, what should it do if used on non-string?

It's usually done this way:

Code:

macro display_a_to_b _str {
  local ..str
  ..str = ''
  virtual at 0
    db _str
    repeat $
      load a byte from %-1
      if a = 'a'
        display 'b'
      else
        display a
      end if
    end repeat
  end virtual
  display 13,10
}
