Hello,
one of the recent patches to the build system broke dependencies:
make[3]: Entering directory `/tmp/build-gcc/gcc'
make[3]: Circular build/gencondmd.o <- insn-flags.h dependency dropped.
make[3]: Circular build/gencondmd.o <- insn-flags.h dependency dropped.
Something like this is bad, because it usually has the potential to
break parallel builds in subtle ways. Please check for such output when
bootstrapping. It is very simple to do afterwards, too, in an up to
date build tree:
$ cd gcc && make
make: Circular build/gencondmd.o <- insn-flags.h dependency dropped.
make: Circular build/gencondmd.o <- insn-flags.h dependency dropped.
$
Cheers,
Ralf
