a simple `find . -name '*' | xargs grep -l SPARC_STACK_BOUNDARY_HACK'
in the gcc src tree gives:

./gcc/ChangeLog
./gcc/function.c
./gcc/config/sparc/sparc.h

and in the gcc/ChangeLog we see that it's been tampered with recently,
http://gcc.gnu.org/ml/gcc-cvs/2003-10/msg00257.html, by geoffk.

Reading in the gcc/config/sparc/sparc.h we see that there is a problem
for SPARC32 systems...

/* Boundary (in *bits*) on which stack pointer should be aligned.  */
/* FIXME, this is wrong when TARGET_ARCH64 and TARGET_STACK_BIAS, because
   then sp+2047 is 128-bit aligned so sp is really only byte-aligned.  */
#define STACK_BOUNDARY (TARGET_ARCH64 ? 128 : 64)
/* Temporary hack until the FIXME above is fixed.  This macro is used
   only in pad_to_arg_alignment in function.c; see the comment there
   for details about what it does.  */
#define SPARC_STACK_BOUNDARY_HACK (TARGET_ARCH64 && TARGET_STACK_BIAS)

Anyone?
