From 44359ced720432b50bc162dfc69c0fd88015c351 Mon Sep 17 00:00:00 2001 From: nathan Date: Mon, 21 Apr 2003 19:48:10 +0000 Subject: Break out coverage routines to new file. * Makefile.in (COVERAGE_H): New variable (C_OBJS): Add coverage.o (coverage.o): New target. (profile.o, loop-init.o, sched-ebb.o, predict.o, tracer.o): Adjust dependencies. (GTFILES): Adjust. (gt-coverage.h): New target. (gt-profile.h): Remove. * profile.h: Remove. Move to ... * coverage.h: ... here. New. #include gcov-io.h. * gcov-io.h: Move function definitions to ... * gcov-io.c: ... here. New. * profile.c: Move coverage routines to coverage.c. (instrument_edges, get_exec_counts, branch_prob, init_branch_prob, end_branch_prob): Adjust. * coverage.c: New. Coverage routines from profile.c (coverage_counter_ref, coverage_init, coverage_finish, coverage_end_function, coverage_begin_output, coverage_counter_ref, get_coverage_counts): Define. * gcov-dump.c, gcov.c: #include gcov-io.c. * libgcov.c: Likewise. Adjust. * loop-init.c: Don't #include profile.h * tracer.c, predict.c, sched-ebb.c: Adjust #includes. * rtl.h: Add coverage prototypes. * toplev.c (compile_file): Init coverage, not branch_prob. Always call coverage_finish. (rest_of_compilation): Call coverage_end_function. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@65897 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/coverage.h | 72 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 gcc/coverage.h (limited to 'gcc/coverage.h') diff --git a/gcc/coverage.h b/gcc/coverage.h new file mode 100644 index 00000000000..f6ead44a597 --- /dev/null +++ b/gcc/coverage.h @@ -0,0 +1,72 @@ +/* coverage.h - Defines data exported from coverage.c + Copyright (C) 1998, 1999, 2000, 2001, 2003 Free Software Foundation, Inc. + +This file is part of GCC. + +GCC is free software; you can redistribute it and/or modify it under +the terms of the GNU General Public License as published by the Free +Software Foundation; either version 2, or (at your option) any later +version. + +GCC is distributed in the hope that it will be useful, but WITHOUT ANY +WARRANTY; without even the implied warranty of MERCHANTABILITY or +FITNESS FOR A PARTICULAR PURPOSE.
