DSPIC, LINKER ERROR

[yo2lio]

HI,

In ASM, Linker don't recognize predefined globals variable such as PORTB if this variables is not initializated before.

http://www.mikroe.com/forum/viewtopic.php?p=65023#65023

For examples :

Code: Select all

  asm
    MOV RCOUNT,W12
  end;

Compile OK.

Code: Select all

  asm
    MOV PORTB,W12
  end;

0:26 E-420 Invalid ASM instruction (132): PORTB (0x000206) W12

Work around :

Code: Select all

  PORTB := PORTB; // skipped by optimizer
  asm
    MOV PORTB,W12
  end;

Florin, it's been the case since the very first compiler version, it is a feature rather than an error. It is not recommended that we link all variables including those which are not used.

As for assembly, hey we are talking here about HL comilers, assembly is provided just for more comfort, it is not intended to be a macro assembler compiler.

Yes true,

I like MikroPascal and I have 17 years of experience in ASM .
I like to switch between MikroPascal and ASM.

It's a very good compiler , have small problems now but is OK for me , I can handle.
