FYI, the 4.7 branch no longer builds for me:

/tmp/gcc47-svn/gcc/config/i386/i386.c: In function 'ix86_expand_prologue':

plus a couple more sets of the same errors for the other plus_constant() calls.

If I remove the "Pmode" argument, the resulting compiler seems to do the right
thing and the test case passes.
