RFR(XXS): 8076532: Fix format warning/error in methodHandles_ppc.cpp

[Volker Simonis]

Hi,

can I please get a review for this tiny, ppc-only change:

https://bugs.openjdk.java.net/browse/JDK-8076532
http://cr.openjdk.java.net/~simonis/webrevs/2015/8076532/

With newer GCCs we currently get the following warning/error:

methodHandles_ppc.cpp: In function ‘void
trace_method_handle_stub(const char*, oopDesc*, intptr_t*,
intptr_t*)’:
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));


Thanks,
Volker
