[Bug c/20738] New: bootstrap failure for avr on head 4.1

["bjoern dot m dot haase at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hi, 
 
when checking out the gcc tree this morning for a clean rebuild and regular  
testsuite run, I observed that bootstrap failed. It seems that it is related  
to some preprocessor issue: 
 
1.) Problem occures when assembling the libgcc library. First failing  
operation is 
 
/home/bmh/gnucvs/head/build/./gcc/xgcc -B/home/bmh/gnucvs/head/build/./gcc/  
-B/usr/local/avr/bin/ -B/usr/local/avr/lib/ -isystem /usr/local/avr/include  
-isystem /usr/local/avr/sys-include -O2 ?-DIN_GCC -DCROSS_COMPILE ? -W -Wall  
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes  
-Wold-style-definition ?-isystem ./include ?-DDF=SF -Dinhibit_libc  
-mcall-prologues -g ?-DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I.  
-I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include  
-I../../gcc/gcc/../libcpp/include ?-DL_mulqi3 -xassembler-with-cpp  
-c ../../gcc/gcc/config/avr/libgcc.S -c libgcc/./_mulqi3.o 
 
and the error message reads 
 
../../gcc/gcc/config/avr/libgcc.S: Assembler messages: 
../../gcc/gcc/config/avr/libgcc.S:72: Error: suffix or operands invalid for  
`clr' 
../../gcc/gcc/config/avr/libgcc.S:72: Error: no such instruction: `clear

make[2]: *** [libgcc/./_mulqi3.o] Fehler 1 
make[1]: *** [stmp-multilib] Fehler 2 
make: *** [all-gcc] Fehler 2 
 
2.) My impression is that the problem is possibly related to some preprocessor  
issue because when executing 
 
/home/bmh/gnucvs/head/build/./gcc/xgcc -B/home/bmh/gnucvs/head/build/./gcc/  
-B/usr/local/avr/bin/ -B/usr/local/avr/lib/ -isystem /usr/local/avr/include  
-isystem /usr/local/avr/sys-include -O2 ?-DIN_GCC -DCROSS_COMPILE ? -W -Wall  
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes  
-Wold-style-definition ?-isystem ./include ?-DDF=SF -Dinhibit_libc  
-mcall-prologues -g ?-DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I.  
-I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include  
-I../../gcc/gcc/../libcpp/include ?-DL_mulqi3 -xassembler-with-cpp  
-c ../../gcc/gcc/config/avr/libgcc.S -c libgcc/./_mulqi3.s 
 
in order to have a look at the assembly output, no file _mulqi3.s is  
generated. Instead the output of the preprocessor is written to stdout. 
 
Yours,
