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 result' ../../gcc/gcc/config/avr/libgcc.S:74: Error: no such instruction: `sbrc r24,0' ../../gcc/gcc/config/avr/libgcc.S:75: Error: too many memory references for `add' ../../gcc/gcc/config/avr/libgcc.S:76: Error: too many memory references for `add' ../../gcc/gcc/config/avr/libgcc.S:76: Error: no such instruction: `shift multiplicand' ../../gcc/gcc/config/avr/libgcc.S:77: Error: no such instruction: `breq __mulqi3_exit' ../../gcc/gcc/config/avr/libgcc.S:77: Error: no such instruction: `while multiplicand!=0' ../../gcc/gcc/config/avr/libgcc.S:78: Error: no such instruction: `lsr r24' ../../gcc/gcc/config/avr/libgcc.S:79: Error: no such instruction: `brne __mulqi3_loop' ../../gcc/gcc/config/avr/libgcc.S:79: Error: no such instruction: `exit if multiplier=0' ../../gcc/gcc/config/avr/libgcc.S:81: Error: too many memory references for `mov' ../../gcc/gcc/config/avr/libgcc.S:81: Error: no such instruction: `result to return register' 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, Björn
