search for: fancy_abort

Hi, I just notice that front-end will add an extra block for switch instruction without default. How could I identify basic blocks added due to this reason? The added codes looks like: sw.default.i625: ; preds = %if.end512 tail call void @fancy_abort(i8* getelementptr inbounds ([38 x i8]* @.str, i64 0, i64 0), i32 3045, i8* getelementptr inbounds ([23 x i8]* @__FUNCTION__.compcode_to_comparison, i64 0, i64 0)) #7, !dbg !8046 unreachable, !dbg !8046 Could I get "unreachable" information from metadata? Thanks a lot!...

With the patch from Chris and then the patch from you combined, the previous error disappeared, but I get another error, reduced to this: ./cc1 -fpreprocessed libgcc2.i -quiet -dumpbase libgcc2.c -mtune=pentiumpro -auxbase-strip libgcc/./_clz.o -g -O2
