1833 The strategy we now use is to pre allocate the top_elt along
1834 with the EH context so that each thread has its own top_elt.

3892 Set *recog_operand_loc only after processing operands, and only
3893 if replace is true. Return a value.
3894 When changing address reload types for operands that didn't get
3895 reloaded, use RELOAD_FOR_OPADDR_ADDRESS for
3896 RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads.

3937 Handle inheritance from auto_inc expressions.
3938 (emit_reload_insns): If reload_in is a MEM, set OLD to
3940 Don't reload directly from oldequiv; if it's a pseudo with a
3941 stack slot, use reload_in[j].

3943 from reg_reloaded_contents.
3944 Include non-spill registers in reload inheritance processing.
3945 Also try to use reload_out_reg to set spill_reg_store /

3958 When looking for a store of a value not loaded in order to call
3959 delete_output_reload, count_occurences should return 0 for no
3960 loads; but discount inherited input reloadill_reg_stored_to.

3979 Don't clear after_call for a CLOBBER.
3980 Keep track of how many hard registers need to be copied from
3981 after_call, and don't clear after_call before we have seen
