1641 out the definition. It was being called incorrectly and at
1642 the wrong times. Until a VMSie can look at this, it's better

1754 The strategy we now use is to pre allocate the top_elt along
1755 with the EH context so that each thread has its own top_elt.
1756 This is necessary as the dynmanic cleanup chain is used on the
1757 top element of the stack and each thread MUST have its own.

3863 Check that reload_in_reg[j] is a MEM before replacing reload_in
3864 from reg_reloaded_contents.
3865 Include non-spill registers in reload inheritance processing.
3866 Also try to use reload_out_reg to set spill_reg_store /

3879 When looking for a store of a value not loaded in order to call
3880 delete_output_reload, count_occurences should return 0 for no
3881 loads; but discount inherited input reloadill_reg_stored_to.

3892 (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS /

3896 (count_occurrences): Use rtx_equal_p for MEMs.
3897 (inc_for_reload): Return instruction that stores into RELOADREG.
3898 New argument two, IN, and rtx. Changed all callers.

3900 Don't clear after_call for a CLOBBER.
3901 Keep track of how many hard registers need to be copied from
3902 after_call, and don't clear after_call before we have seen
