There is one regression for sh-elf/-m4 and sh-elf/-m4/-ml

gcc.c-torture/execute/stdarg-2.c execution, -O2



I'm currently working on a merge from mainline (yesterday 12:00 UTC) into the sh-elf-4_1-branch. I also see a failure of stdarg-2.c for sh-elf/-m4/-ml at "-O3 -fomit-frame-pointer" and "-O3 -g" (-m4 -mb not tested). f12 returns an incorrect result, but not when you re-run the program. I suspect that the va_list has not been set up before it is used. (foo is inlined into f12).

There is also a failure of execute/20000603-1.c at -O2. Do you see
that too? f is miscompiled: in sched1, the DFmode store is moved after
the load.
