  double x = 4, y;
  __asm__ volatile ("" : "=r,r" (x), "=r,r" (y) : "%0,0" (x), "m,r" (8));
}
============================================

bug.c: In function 'void foo()':
bug.c:5: error: Failure trying to reload:

------- Comment #2 from reichelt at gcc dot gnu dot org  2008-03-04 07:38 -------
That's not an error-recovery issue. Reload prints the error via
  fatal_insn ("Failure trying to reload:", set);
which outputs some data and calls fancy_abort. So that's just a disguised ICE.

The ICE reappeared on the trunk:

bug.c:5: internal compiler error: output_operand: floating constant misused
Please submit a full bug report, [etc.]

Jakub, this was probably caused by your the patch for PR39058.
Maybe the IRA merge just papered over the real problem.
