2330 (append_include_chain): Brought over from cppfiles.c. Mark
2331 dirs as system include dirs if and only if appending to
2332 system include path. If opts->verbose, print a notice when a

7893 out the definition. It was being called incorrectly and at

8006 The strategy we now use is to pre allocate the top_elt along
8007 with the EH context so that each thread has its own top_elt.
8008 This is necessary as the dynamic cleanup chain is used on the
8009 top element of the stack and each thread MUST have its own.

10115 Treat reload_override_in more similar to inherited reloads.

10117 For flag_expensive_optimizations, add an extra pass to remove

10127 Include non-spill registers in reload inheritance processing.
10128 Also try to use reload_out_reg to set spill_reg_store /

10141 When looking for a store of a value not loaded in order to call
10142 delete_output_reload, count_occurrences should return 0 for no
10143 loads; but discount inherited input reloadill_reg_stored_to.

10165 that much copies, or we see a different instruction.
