No, they are distinct bugs in the target files.  In this BZ it's the fault of
the cris backend.  In 68538, it appears to be a problem in the x86 backend.

After seeing this report, I'm realizing that Bug 71009 which I filed might be a
duplicate of this one; it's also an ICE at the same place in emit-rtl.c for the
same reason of can_create_pseudo_p having an issue. It's just for a different
target though.

This is still a problem on the trunk.  I'm not at all familiar with the CRIS
port, but ISTM that we should never be calling copy_to_mode_reg when
!can_create_pseudo_p because copy_to_mode_reg always creates a new pseudo.

Thanks for the report.  Assigning to myself, hoping to have a look soon.
Also seen on trunk r231039 for cris-elf.
