Hello everyone.
I am trying to use the C function in AA, but it doesnt work. This is my script

Code:
[ENABLE]
registersymbol(newmem)
alloc(newmem,$100)
createthread(newmem)

registersymbol(math)
alloc(math,$10)

math+0:
dd (float)3
math+4:
dd (float)7

newmem:
  pushad
  movss xmm0,[math+0]
  movss xmm1,[math+4]

{$c}
float addf(float x, float y)
{
    return x + y;
}

{$ccode xmmReg0=xmm0 xmmReg1=xmm1}
xmmReg0.f0 = addf(xmmReg0.f0, xmmReg1.f0);

{$asm}
  //movss xmm0,[math+0]
  //addss xmm0,[math+4]
  movss [math+8],xmm0

  popad
  jmp newmem

[DISABLE]

newmem:
  ret

unregistersymbol(*)
dealloc(*)


This is the error message:
Code:
Not all code is injectable.
(C Error Error at line 25: error: declaration
expected
)
Are you sure you want to edit it to this?


However, when I do not use the function and perform the calculation directly, it executes correctly.

Code:
[ENABLE]
registersymbol(newmem)
alloc(newmem,$100)
createthread(newmem)

registersymbol(math)
alloc(math,$10)

math+0:
dd (float)3
math+4:
dd (float)7

newmem:
  pushad
  movss xmm0,[math+0]
  movss xmm1,[math+4]

{$ccode xmmReg0=xmm0 xmmReg1=xmm1}
xmmReg0.f0 = xmmReg0.f0 + xmmReg1.f0;

{$asm}
  //movss xmm0,[math+0]
  //addss xmm0,[math+4]
  movss [math+8],xmm0

  popad
  jmp newmem

[DISABLE]

newmem:
  ret

unregistersymbol(*)
dealloc(*)

{$c} blocks need a terminating {$asm}; you can't just go directly into a {$ccode} block

Move the {$c} block above newmem

Code:
{$c}
...
{$asm}

...
newmem:
  ...
{$ccode ...}
...
{$asm}

Moved from Auto Assembler Tutorials as this is not a tutorial.
