I'll try that at the end of January. I've vacation that time.

Hi Gunther,
Today I've noticed  one JWASM anomaly or maybe better name it SINGULARITY .
Let me explain it:
Acorrding to paragraph 3.2 FASTCALL Register Calling Convention of JWASM manual :

In 64-bit mode, FASTCALL means the standard Windows 64 ABI if output format is not ELF.For -elf64, there is no FASTCALL support implemented yet.

I wrote a simple test app (see the attachment ) in such a way  as if JWASM already had FASTCALL support and guess what ... it worked !!!
Let's go back to manual and read:

To make FASTCALL the default calling convention, there are 3 ways:

    Commandline options -Gr ( or -win64 )
    Second argument of the .MODEL directive: .MODEL FLAT, FASTCALL
    Directive OPTION LANGUAGE: FASTCALL

Now let's try to set calling convention to FASTCALL in all 3 ways and see what results we will get:

• -Gr  -> testFC.asm : Error A2168: General Failure
  
• .MODEL FLAT, FASTCALL -> test1.asm(9) : Warning A4095: Multiple .MODEL directives, .MODEL ignored
                                              test1.asm : Error A2168: General Failure
  
• OPTION LANGUAGE: FASTCALL -> test1.asm : Error A2168: General Failure
  

Thus, JWASM doesn't allow us to specify FASTCALL for elf64  , then,  why does it work  ?

--- NOTE: testFC was compiled with JWasm v2.11 and tested on Ubuntu 14.4 64 bit ---
The output should be something like this:

--------- INFO ---------

User-level applications use as integer registers for passing the sequence:
rdi, rsi, rdx, rcx, r8 and r9.

--------- TEST ---------

RDI=0x215bd000, RSI=12345, RDX=67890, RCX=54321, R8=9876, R9=12345

--------- END ----------

 As need for speed underground - my build - with installer with docs and licenses, seh, unicode support ... looks well (and maybe need num to ext for unpack).

Hi Adamanteus
Windows 8.1 is unable to read your compressed folders :icon_exclaim:

 If to move numbers in archives filenames to extensions (as JWasm.zip.00x) - my unzipping easy.
P.S. That's maybe admins will change forum settings for attachments, that to upload as one archive.
