I have a question about the partial pre (-ftree-partial-pre) optimization
that was added in GCC 4.8. I have noticed that this optimization is slowing
down the bitmnp01 benchmark in the EEMBC1.1 suite on MIPS. I see this with
the 4.8 GCC and with ToT GCC. Comparing "-O3 -fno-tree-partial-pre" vs.

Honza,
in calls.c:expand_call, I see the following code:
...
#ifdef REG_PARM_STACK_SPACE
/* If outgoing reg parm stack space changes, we can not do sibcall. */
|| (OUTGOING_REG_PARM_STACK_SPACE (funtype)
!= OUTGOING_REG_PARM_STACK_SPACE (TREE_TYPE (current_function_decl)))
Snapshot gcc-4.8-20131212 is now available on
ftp://gcc.gnu.org/pub/gcc/snapshots/4.8-20131212/
and on various mirrors, see http://gcc.gnu.org/mirrors.html for details.
This snapshot has been generated from the GCC 4.8 SVN branch
with the following options: svn://gcc.gnu.org/svn/gcc/branches
