gcno file: do not stream block flags (PR gcov-profile/80031).
2017-04-28 Martin Liska <mliska@suse.cz>
PR gcov-profile/80031
* gcov-dump.c (tag_blocks): Just print number of basic blocks.
* gcov-io.h (GCOV_TAG_BLOCKS_NUM): Remove unused macro.
* gcov.c (read_graph_file): Read just number of blocks.
* profile.c (branch_prob): Do not stream 0 flags per a basic
block.
