(From Staffan Larsen:)

BTW, I got compilation errors with Xcode 4.6.3 when compiling only the OpenJDK code:

/Users/staffan/mercurial/jdk9-hs-rt/hotspot/src/share/vm/trace/traceStream.hpp: In member function ‘void TraceStream::print_val(const char*, s8)’:
/Users/staffan/mercurial/jdk9-hs-rt/hotspot/src/share/vm/trace/traceStream.hpp:69: warning: format ‘%lld’ expects type ‘long long int’, but argument 4 has type ‘s8’

Configure flags were:
configure --disable-zip-debug-info --with-debug-level=release --with-jobs=7 --with-conf-name=openjdk-release --enable-openjdk-only


I think this is a fix:

diff --git a/src/share/vm/trace/traceStream.hpp b/src/share/vm/trace/traceStream.hpp

  void print_val(const char* label, s8 val) {

+ _st.print("%s = "INT64_FORMAT, label, (int64_t) val);
