My build robot shows a new build error, which I guess is caused/uncovered by your genrecog change on bfin-elf (see eg. build http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=355667): build/genrecog /home/jbglaw/repos/gcc/gcc/common.md /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md \ insn-conditions.md > tmp-recog.c /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:745: warning: operand 0 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:1953: warning: source missing a mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:1994: warning: source missing a mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:1994: warning: source missing a mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2005: warning: source missing a mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2005: warning: source missing a mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2128: warning: operand 1 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2139: warning: operand 1 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2150: warning: operand 2 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2162: warning: operand 2 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2228: warning: operand 1 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2238: warning: operand 1 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2248: warning: operand 2 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2259: warning: operand 2 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2720: warning: operand 0 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2742: warning: operand 0 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:2742: warning: operand 1 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:3231: warning: operand 4 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:3247: warning: operand 3 missing mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:1971: warning: source missing a mode? /home/jbglaw/repos/gcc/gcc/config/bfin/bfin.md:1971: constraints not supported in define_split make[1]: *** [s-recog] Error 1 make[1]: Leaving directory `/home/jbglaw/build/bfin-elf/build-gcc/gcc' make: *** [all-gcc] Error 2 Would be nice if the bfin maintainer or you would come up with a fix.
