[Bug target/37378] [4.4 Regression] Revision 139827 causes Divide_X

[jakub at gcc dot gnu dot org]

------- Comment #16 from jakub at gcc dot gnu dot org  2008-10-24 15:22 -------
I guess e.g. ia64_expand_prologue could add all those regs that it
/* Even if we're not going to generate an epilogue, we still
   need to save the register so that EH works.  */
if (! epilogue_p)
  emit_insn (gen_prologue_use (XXX_reg));
when epilogue_p as USEs into CALL_INSN_FUNCTION_USAGE of all noreturn calls.
