DTraceAllocProbes in x86-64 templateTable?

Hi folks,

I noticed that the call to DTraceAllocProbes in the 64-bit x86
templateTable is directly after a jump instruction that jumps over it.
 I don't have dtrace to check, but that can't be right, can it?

It's line 3245 of:

http://hg.openjdk.java.net/jdk7/hotspot-comp-gate/hotspot/file/c028504fdaa6/src/cpu/x86/vm/templateTable_x86_64.cpp

The 32-bit version appears to have this code correctly placed above the jmp.

Jeremy
