--- Comment #1 from Sandra Loosemore <sandra at codesourcery dot com> ---
Hmmm, this looks like a bug in LRA exposed by the change to register alloc
order. In particular this comment in the code just above the assertion seems
to reflect an incorrect assumption:
/* We did not assign hard regs to reload pseudos after two
iteration. It means something is wrong with asm insn
constraints. Report it. */
since there is no inline asm in the test case.
