Hi, I intend to add some assembler sources to libgcc build. Using the straight forward way in ./gcc/config/avr/t-avr
@ -52,7 +50,30 @@ LIB1ASMFUNCS = \ ... + _ffssi2 \ + _ffshi2 \ + _loop_ffsqi2 \ + _ctzsi2 \ + _ctzhi2 \ + _clzdi2 \ + _clzsi2 \ + _clz \ + _paritydi2 \ + _paritysi2 \ + _parityhi2 \ + _popcounthi2 \ + _popcountsi2 \ + _popcountdi2 \ + _popcountqi2 \ + _bswapsi2 \ + _bswapdi2 all works fine except that I get warnings from make for hi functions: (in <build>/avr/ligbcc) Makefile:375: warning: overriding commands for target `_ffshi2.o' ../../../../gcc.gnu.org/trunk/libgcc/siditi-object.mk:15: warning: ignoring old commands for target `_ffshi2.o' Makefile:375: warning: overriding commands for target `_ctzhi2.o' ../../../../gcc.gnu.org/trunk/libgcc/siditi-object.mk:15: warning: ignoring old commands for target `_ctzhi2.o' Makefile:375: warning: overriding commands for target `_parityhi2.o' ../../../../gcc.gnu.org/trunk/libgcc/siditi-object.mk:15: warning: ignoring old commands for target `_parityhi2.o' Makefile:375: warning: overriding commands for target `_popcounthi2.o' ../../../../gcc.gnu.org/trunk/libgcc/siditi-object.mk:15: warning: ignoring old commands for target `_popcounthi2.o' make: `_clzhi2.o' is up to date. Am I something missing? Adding fragments to LIB1ASMFUNCS should filter them out in filter-out. Adding these function to LIB2FUNCS_EXCLUDE does not help; the warnings persist (I see correct LIB2FUNCS_EXCLUDE in ./gcc/libgcc.mvars). Setup is with current trunk (175011): ../../gcc.gnu.org/trunk/configure --target=avr --prefix=/local/gnu/install/gcc-4.7 --disable-nls --disable-shared --enable-languages=c,c++ Johann
