Call Function In Assembly Bug ?

[Guest Leon]

Below is a suggested bug report format:

 

Bug description:

CALL function in ASM does not seem to work

 

Steps to reproduce:

 

CODE:

 

#include <system.h>

 

void main()

{

asm

{

CLRW

 

MOVWF _portc

MOVWF _trisc

 

 

CALL ROUTINE

MOVLW 0xFF

MOVWF _portc

 

GOTO LABELEND

 

ROUTINE :

 

MOVLW 0x03

MOVWF _portc

RETURN

 

LABELEND :

 

}

}

 

 

Expected behaviour:

How a fixed program should behave it should not give an error.

 

 

Is the problem 100% reproduceable:

this problem happens every time

 

IDE version: SourceBoost IDE 6.95

Compiler: Compiler BoostC

Compiler version: 6.95

Target device: PIC16F877A

OS: Windows XP Profesional SP3 Dutch

 

Comments:

If you replace the "CALL" with "GOTO" compiling is not a problem, of course the GOTO is not the same as the call.

replacing is just to check spelling and to check if the software works.

Leon

Hi Leon,

 

You may have to put your ROUTINE into a separate function like this:

 

void MyFunc(void) {
 asm
 {
MOVLW 0x03 
MOVWF _portc
RETURN
 }
}

 

Cheers
