>Description:
Building a sh-elf compiler fails while building __muldi3
for libgcc:

../../../gcc/gcc/libgcc2.c: In function `__muldi3':
../../../gcc/gcc/libgcc2.c:367: RTL flag check: access macro used with unexpected rtx code `jump_insn' in dbr_schedule, at reorg.c:3631

A similar failure occurs while building the same function
for with the sh-netbsdelf configuration I posted some time
ago (problems in updating this configuration prompted this
report).
>How-To-Repeat:
Attempt to build a sh-elf compiler.
>Fix:
The function can be compiled with -O0.
