This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.

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
