[avr-gcc-list] What has changed between WinAVR 20070525rc2 and WinAVR 20080430?

[Bob Paddock]

Can anyone tell me what has changed from:

avr-gcc (GCC) 4.1.2 (WinAVR 20070525rc2)

to?:

avr-gcc (WinAVR 20080430) 4.3.0

I recompiled code for a working product using 4.1.2 with 4.3.0 and it
no longer works correctly.

Fairly complex product so trying to localize the problem would not be
all that much fun, without some insights as to what might be
different.

The unit has a bit mapped display.  With 4.3.0 I have random pixels
that I don't have with 4.1.2, which probably indicates that I have
something marginal in my display driver timing.  When I assert INT0
the unit eventually locks up with 4.3.0, but not with 4.1.2.

All rather vague descriptions, I know...

 

RAM and EEPROM usage remained the same, code size

grew by 516 bytes going from 4.1.2 to 4.3.0.
