Hello fellow SPARC friends.

Looking at the comments in sys/arch/sparc/include/frame.h it seem to be 
incorrect:
...
/*
  * CC64FSZ (C Compiler 64-bit Frame SiZe) is the size of a stack frame 
used
  * by the compiler in 64-bit mode.  It is (16)*8; space for 8 ins, 8 outs.
  */
#define CC64FSZ		176
...


But 16 * 8 = 128.

Can anyone share some knowledge on why CF64FSZ is 176 bytes and not 128 
bytes as the comment says?
