There are no regressions on x86-linux cross sh4-unknown-linux-gnu.

Created an attachment (id=9898)

maybe fix mode switching vs abnormal edges

Try this patch on top of the other.

The patch gets rid of the ICE and makes it possible to build
libjava with --enable-cheching on sh4-unknown-linux-gnu again.
Thanks!

code...

There are no new failures on c/c++/objc tests with the patch but
it makes 120 new failures on gfortran execution test.  The patched
compiler still fails for libjava/interpret.cc and Andrew's
reduced testcase.

BTW, I've found that Andrew's testcase fails even on i686-linux with
-O2 -fnon-call-exceptions:

  internal compiler error: in expand_assignment, at expr.c:3929

I've filed it as PR 23714.

Here is the reduced testcase:
void run (void) {
  float stack[1];
  float *sp = stack;
  try
  {
float value2 = ((float) *(--sp));
float value1 = ((float) *(--sp));
*(sp++) = (value1 - value2);
  }
  catch (int *ex)
  {
  }
}
