The -da -O0 changes of the last patch are:
test.c.275r.split1
test.c.277r.dfinit
test.c.278r.mode_sw
test.c.279r.asmcons
test.c.284r.ira
test.c.285r.reload
-test.c.289r.split2
test.c.292r.pro_and_epilogue
test.c.295r.jump2
+test.c.306r.split3
test.c.307r.stack
test.c.308r.alignments
test.c.310r.mach
test.c.311r.barriers
test.c.316r.shorten
test.c.317r.nothrow
test.c.318r.dwarf2
test.c.319r.final
test.c.320r.dfinish
while the first one just adds test.c.306r.split3 and doesn't remove
test.c.289r.split2 and the second one just adds test.c.313r.split5
before test.c.316r.shorten.
