from register elimination as PRE_MODIFY / POST_MODIFY increments.
Do not attempt to handle MEM inside auto-inc expressions.
* reload1.c (eliminate_regs_1): Do not attempt to handle elimination
of a register modified by an auto-inc expression. However, do handle
elimination of a register used as PRE_MODIFY / POST_MODIFY increment.

by an auto-inc expression. Disable register elimination rules whose
