2251 The strategy we now use is to pre allocate the top_elt along
2252 with the EH context so that each thread has its own top_elt.

4347 reload_reg_free_before_p test with reload_reg_used_at_all test, and

4350 Treat reload_override_in more similar to inherited reloads.
4351 Handle (subreg (reg... for inheritance.
4352 For flag_expensive_optimizations, add an extra pass to remove
4353 unnecessary reloads from known working inheritance.

4356 (emit_reload_insns): If reload_in is a MEM, set OLD to
4358 Don't reload directly from oldequiv; if it's a pseudo with a

4372 Add code to call delete_output_reload for stores with no matching load.
4373 Set / use spill_reg_stored_to.

4376 When looking for a store of a value not loaded in order to call
4377 delete_output_reload, count_occurences should return 0 for no
4378 loads; but discount inherited input reloadill_reg_stored_to.
4379 Do checks for extra uses of REG. Changed all

4389 (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS /

4393 (count_occurrences): Use rtx_equal_p for MEMs.
4394 (inc_for_reload): Return instruction that stores into RELOADREG.
4395 New argument two, IN, and rtx. Changed all callers.

4397 Don't clear after_call for a CLOBBER.
4398 Keep track of how many hard registers need to be copied from
4399 after_call, and don't clear after_call before we have seen
