Simplify streaming of SCC components
this patch saves few bytes from SCC streaming. First we stream end markers
that are fully ignored at stream in.
Second I missed streaming of emtry_len in the previous change so it is
pointlessly streamed for LTO_trees. Moreover entry_len is almost always 1
(always during gcc bootstrap) and thus it makes sense to avoid stremaing it
in majority of cases.
gcc/ChangeLog:
2020-05-21 Jan Hubicka <hubicka@ucw.cz>
* lto-streamer-in.c (lto_read_tree): Do not stream end markers.
(lto_input_scc): Optimize streaming of entry lengths.
* lto-streamer-out.c (lto_write_tree): Do not stream end markers
(DFS::DFS): Optimize stremaing of entry lengths
