[Bug target/19636] Can't compile ethernut OS (avr-gcc)

Found an important hint:

If the switch instruction is replaced with else ifs, the file is also
compilable with the -Os option. It seems that the avr-gcc >4.0 can only
optimize a limited number of cases (the file usart.i has 33 cases in one switch
statement).

Yes, the bug is still present in gcc-4.1.1, see below. I also had problems
building gcc-4.1.1 for avr. libssp doesn't compile for this target, hence I had
to disable it  by passing --disable-libssp to configure.

usart.c: In function ‘UsartIOCtl’:
usart.c:821: error: unable to find a register to spill in class
‘BASE_POINTER_REGS’
usart.c:821: error: this is the insn:

(reg:HI 24 r24)) 12 {*movhi} (nil)
(nil))
usart.c:821: confused by earlier errors, bailing out

Sorry, no. Your comment has been the latest news.

Can you try using GCC 4.1.1 and see if you can still reproduce this bug? That
would be very informative.

Compiling of usart.i still fails:

usart.c: In function 'UsartIOCtl':
usart.c:821: error: unable to find a register to spill in class
'BASE_POINTER_REGS'
usart.c:821: error: this is the insn:

(reg:HI 24 r24)) 12 {*movhi} (nil)
(nil))
usart.c:821: confused by earlier errors, bailing out

Tested with: 4.0.3 20051123, 4.1.0 20051202, 4.2.0 20051202

It compiles OK with 3.4.5

I can confirm this bug for 4_0 and head (using -Os).

Note:
gcc-head-2004-12-07 compiles usart.i OK.
gcc-head-2004-12-29 fails with:

usart.c: In function 'UsartIOCtl':

The testcase compiles successfully with avr-gcc on 3.3.2, and 3.4.3, using
-mmcu=atmega128.
Could someone with sufficient permissions please set the "Known To Work" field.

Dieter, could you confirm which device you're compiling for?
