Momentan verwende ich den avr-gcc 3.4.6
Unter Windows bzw. Linux unterstützt er jedoch unterschiedliche AVRs, so daß ich zeimlich verwirrt darüber bin.

Reading specs from e:/WinAVR-20060421/lib/gcc/avr/3.4.6/specs
Configured with: ../gcc-3.4.6/configure --prefix=/c/WinAVR --target=avr --enable

Thread model: single
gcc version 3.4.6

Target specific options:
-msize Output instruction sizes to the asm file
-mshort-calls Use rjmp/rcall (limited range) on >8K devices
-mno-tablejump Do not generate tablejump insns
-mtiny-stack Change only the low 8 bits of the stack pointer
-mcall-prologues Use subroutines for function prologue/epilogue
-mno-interrupts Change the stack pointer without disabling interrupts
-mint8 Assume int to be 8 bit integer
-mmcu= Specify the MCU name
-minit-stack= Specify the initial stack address
There are undocumented target specific options as well.
AVR options:
-mmcu=[avr-name] select microcontroller variant
[avr-name] can be:
avr1 - AT90S1200, ATtiny1x, ATtiny28
avr2 - AT90S2xxx, AT90S4xxx, AT90S8xxx, ATtiny22
avr3 - ATmega103, ATmega603
avr4 - ATmega83, ATmega85
avr5 - ATmega161, ATmega163, ATmega32, AT94K
or immediate microcontroller name.
-mall-opcodes accept all AVR opcodes, even if not supported by MCU
-mno-skip-bug disable warnings for skipping two-word instructions
(default for avr4, avr5)
-mno-wrap reject rjmp/rcall instructions with 8K wrap-around
(default for avr3, avr5)

Wie leicht zu sehen ist unerscheiden sich beide deutlich bei den unterstützten AVRs, sind aber beide Version 3.4.6 :-k
Weiß da jemand näheres oder ne Idee wo was schiefgeht? Was der Linux-gcc sagt stimmt jedenfalls mit den Quellen überein (gcc-core-3.4.6)
Unter Windows bzw. Linux unterstützt er jedoch unterschiedliche AVRs, so daß ich zeimlich verwirrt darüber bin.
