With newer GCCs we currently get the following error:

/OpenJDK/jdk9-hs-comp/hotspot/src/cpu/ppc/vm/methodHandles_ppc.cpp: In function ‘void trace_method_handle_stub(const char*, oopDesc*, intptr_t*, intptr_t*)’:
/OpenJDK/jdk9-hs-comp/hotspot/src/cpu/ppc/vm/methodHandles_ppc.cpp:469:66: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 6 has type ‘intptr_t* {aka long int*}’ [-Werror=format=]
                 adaptername, mh_reg_name, (intptr_t) mh, entry_sp);

for this code code in methodHandles_ppc.cpp:

  tty->print_cr("MH %s %s="INTPTR_FORMAT " sp=" INTPTR_FORMAT,
                adaptername, mh_reg_name, (intptr_t) mh, entry_sp);

The fix is trivial - just use the "p2i()" helper function to cast the pointers to the appropriate type:

  tty->print_cr("MH %s %s="INTPTR_FORMAT " sp=" INTPTR_FORMAT,
                adaptername, mh_reg_name, p2i(mh), p2i(entry_sp));
