Add zstd support for LTO bytecode compression.
2019-07-03 Martin Liska <mliska@suse.cz>
* Makefile.in: Define ZSTD_LIB.
* common.opt: Adjust compression level
to support also zstd levels.
* config.in: Regenerate.
* configure: Likewise.
* configure.ac: Add --with-zstd and --with-zstd-include options
and detect ZSTD.
* doc/install.texi: Mention zstd dependency.
* gcc.c: Print supported LTO compression algorithms.
* lto-compress.c (lto_normalized_zstd_level): Likewise.
(lto_compression_zstd): Likewise.
(lto_uncompression_zstd): Likewise.
(lto_end_compression): Dispatch in between zlib and zstd.
(lto_compression_zlib): Mark with ATTRIBUTE_UNUSED.
(lto_uncompression_zlib): Make it static.
* lto-compress.h (lto_end_uncompression): Fix GNU coding style.
* lto-section-in.c (lto_get_section_data): Pass info
about used compression.
* lto-streamer-out.c: By default use zstd when possible.
* timevar.def (TV_IPA_LTO_DECOMPRESS): Rename to decompression
(TV_IPA_LTO_COMPRESS): Likewise for compression.
