All is bad again after the fix for PR42220:
2010-03-07 Bernd Schmidt <bernd.schm...@analog.com>
PR rtl-optimization/42220
* regrename.c (scan_rtx) <case STRICT_LOW_PART, ZERO_EXTRACT>:
Use verify_reg_tracked to determine if we should use OP_OUT rather
than OP_INOUT.
(build_def_use): If we see an in-out operand for a register that we
know nothing about, treat is an output if possible, fail the block if
not.
