2672 (cpp_get_token): Break out string parsing code to
2673 parse_string. Use skip_comment for CHILL comments too. Use
2674 copy_comment for put_out_comments instead of dinking with

2676 unless it's necessary.

2750 (append_include_chain): Brought over from cppfiles.c. Mark
2751 dirs as system include dirs if and only if appending to
2752 system include path. If opts->verbose, print a notice when a

2754 exist. Fix memory leak: this function is not supposed to copy

8426 The strategy we now use is to pre allocate the top_elt along
8427 with the EH context so that each thread has its own top_elt.

10561 When looking for a store of a value not loaded in order to call
10562 delete_output_reload, count_occurrences should return 0 for no
10563 loads; but discount inherited input reloadill_reg_stored_to.

10574 (reload_reg_free_for_value_p): Handle RELOAD_FOR_OPERAND_ADDRESS /

10578 (count_occurrences): Use rtx_equal_p for MEMs.
10579 (inc_for_reload): Return instruction that stores into RELOADREG.
10580 New argument two, IN, and rtx. Changed all callers.

10582 Don't clear after_call for a CLOBBER.
10583 Keep track of how many hard registers need to be copied from
10584 after_call, and don't clear after_call before we have seen
10585 that much copies, or we see a different instruction.
