[avr-gcc-list] avr-gcc bug - Part 2

[Peter Bosscha]

Please be aware that I'm using Win NT, downloaded my stuff from:

 

http://combio.de/avr/ (Also pointed to from www.avrfreaks.net)

 

Tried to change processors that did not help either.

My code looks as follows:

 

.global main
main:
/* prologue: frame size=0 */
     ldi r28,lo8(__stack - 0)
     ldi r29,hi8(__stack - 0)
     out __SP_H__,r29
     out __SP_L__,r28
/* prologue end (size=4) */
     ldi r24,lo8(0)
     rcall mycall
     mov r28,r24
     ldi r24,lo8(1)
     rcall mycall
     mov r29,r24
.L11:
     tst r28
     breq .L11
     ldi r24,lo8(0)
     rcall mycall
     tst r24
     brge .L12
     tst r29
     brne .L13
     rjmp .L11
.L12:
     ldi r24,lo8(1)
     rcall mycall
     rjmp .L11
.L13:
     ldi r24,lo8(2)
     rcall mycall
     rjmp .L11
__stop_progIi__:
     rjmp __stop_progIi__
/* epilogue end (size=1) */
/* function main size 27 (22) */

 

Differences between this code and Dennis's are:

- registers handling (R28 / R29)

- BRGE instruction instead of BRLT

 

The only possible solution in my mind is that the fix has not found its way from Linux into the Windows version.
