[avr-gcc-list] new AVR-GCC bug

[rudi gerrits]

Hi,

 

I am happy to see that the SRAM allocation bug is fixed in the latest avr-gcc version.

-> avrgcc20010211.exe , downloaded from http://combio.de/avr/index.html

However , a new bug seems to have popped up.

 

The following code is emitted wrong:

 

 while ((inp(USR) & (1<<RXC)) == 0)
 {
   if ( i == 5)   
   {
    // receive timeout
    return 0;
   }
 }

It worked fine with Volker's version.

If I remove the inner statements it works like it should have.

Same problem if the while() loop is changed into a for() loop.

It seems that the bit test is translated into this :

 

   in r18,11
   tst r18
   brlt .L18
 

With the old compiler the "brlt" was "brge".

 

Can someone look into this ?

 

Thanks.
