Hi,

We've just updated the 2.14 release binaries and code in github with the fix for CreateVariable.

Hi ToutEnMasm,
Use a search in VS and find the first 'myassert'
than click with right button on it and chose "Ind all references"
they already have /**/myassert, just move the '*/' to the end of line

let me know if you succeed to build without myassert, please

[TouEnMasm]

I have put all myassert in comment but,same error

[habran]

If you google that error, you will find out that it happens to others as well.
It has to do something with Visual Studio.

[habran]

ToutEnMasm, try to put in Property Pages C\C++\Preprocessor _NDEBUG
and in a linker _DEBUG

[TouEnMasm]

Found from where it com:
tokenize.c

static void StartComment( const char *p )
/***************************************/
{
    while ( isspace( *p ) ) p++;
    if ( *p == NULLC ) {
        EmitError( COMMENT_DELIMITER_EXPECTED );
        return;
    }
    ModuleInfo.inside_comment = *p++;
    if( strchr( p, ModuleInfo.inside_comment ) )
        ModuleInfo.inside_comment = NULLC;
    return;
}

the assertion failed using isspace say it's a bug using bad char to find the zero.
recommended method is to use len>> if len = 0

Great find :t
Did you find solution for that?

[TouEnMasm]

The line is a "comment µ",I let you search why there is a bug here in debug mode ?!.

[TouEnMasm]

I try my best proc this time

         .686P         
      .MMX
      .XMM
                                 
         .model flat, stdcall                     
         option casemap :none 
         ExitProcess PROTO :DWORD 
         includelib kernel32.lib              
   .code

   start:
   comment q
   rien                       
   q
   
   invoke ExitProcess,0
   end start      

result

Thanks ToutEnMasm :t
I will look at it ASAP

Hallo,

what does this message mean?

Here is an example of code that I use

Code Select Expand

.if rax
xor rbx, rbx
           .WHILE rbx < rax
                 invoke printf, offset _Dis, _insn[rbx].address, _insn[rbx].mnemonic, _insn[rbx].op_str;
            inc rbx
        .ENDW
.else
    nop
.endif

Description

The /LARGEADDRESSAWARE option tells the linker that the application can handle addresses larger than 2 gigabytes. In the 64-bit compilers, this option is enabled by default. In the 32-bit compilers, /LARGEADDRESSAWARE:NO is enabled if /LARGEADDRESSAWARE is not otherwise specified on the linker line.
If an application was linked with /LARGEADDRESSAWARE, DUMPBIN /HEADERS will display information to that effect.

This is required? After all, I do not break the boundaries of memory.

Regards!

Hi,

When doing 64bit coding you cannot use OFFSET to obtain the address of a variable (as you would in 32bit as an argument to invoke etc).

To obtain an address you should use LEA, or for an argument to invoke you can use the ADDR operator.

For example:

Code Select Expand



lea rdi,myBuffer   ; get the address of myBuffer into RDI.

invoke myProc, ADDR myBuffer2, myBuffer



The warning relating to largeaddressaware is telling you that you're trying to create a 64bit image that is using 32bit style relocations (for runtime loading by the OS).

Hallo,

the difficulty was not offset, but instead a pointer that has not been properly defined. With Offset is also interesting, since I did not notice the difference when assembled program. Thanks for the help :t

When doing 64bit coding you cannot use OFFSET to obtain the address of a variable (as you would in 32bit as an argument to invoke etc).

There are 64Bit offsets as well JWASM and ml64 handle them (either by using MOV or making them RIP-relative). I guess you mean the problem when using offsets/labels with SIB-Addressing, which is not possible**  because these kind of addressing is not RIP-relative.

regards

**except if using LARGEADDRESSAWARE:NO, which tells that that our image is in [0, 2³²) thus 64bit offsets could be truncate to 32bit.

Hello, please, can you check this about rip addressing.
This is output from yasm and as on other side of moon.

Code Select Expand

as output
0000000000000000 <_start>:
   0:   8a 05 08 00 00 00       mov    al,BYTE PTR [rip+0x8]        # e <_start+0xe>

The same code with adjustment using hjwasm:
