[Mspgcc-users] Is this a Bug???

[Yu Zhijie]

i'm a beginer of msp430-gcc. i meet one problem for inline asm.

my os is Win2K Professional, and mspgcc-20030506.exe is download from 
http://sourceforge.net/project/showfiles.php?group_id=42303

the target MCU is MSP430F149.



the file of main.c

#include <io.h>
#include <setjmp.h>

unsigned char c1;

int main(void)
{
  asm volatile("jmp IsThisBug \n\t"::);  

  return 0;
}

void IsThisBug()
{
  c1++;
}

and the code in *.elf.lst is:


00001140 <main>:

unsigned char c1;

void main(void)
{
    1140: 31 40 00 0a  mov #2560, r1 ;#0x0a00
  asm volatile("jmp IsThisBug \n\t"::);  
    1144: 07 3c        jmp $+16      ;abs 0x1154  /*** ERROR address for 0x1154 
?? ****/
}
    1146: 30 40 50 11  br #0x1150  ;

0000114a <IsThisBug>:

void IsThisBug()
{
  c1++;
    114a: d2 53 00 02  inc.b &0x0200  ;
}    114e: 30 41        ret   


But the jmp address at 0x1144 is ERROR!   
    
It seems like a Byte/Word problem, or the bug of my code???????

thanks very much!!!
