Add prototypes for cfgbuild.c. * cfgcleanup.h: New. Add prototypes for cfgcleanup.c. * cfgloopmanip.h: New. Add prototypes for cfgloopmanip.c. * dominance.h: New. Add prototypes for dominance.c. * cfgloop.h: Move some prototypes/enum to cfgloopmanip.h and include it. * cfghooks.h: (struct profile_record) Relocate here. Relocate 2 prototypes from basic-block.h. * basic-block.h: Move prototypes and struct to new header files. Include cfgbuild.h, cfgcleanup.h, and dominance.h. * rtl.h: Move a few prototypes to new header files. * cfgcleanup.c (merge_memattrs): Make static. * genopinit.c (main): Add predict.h to list of includes. * predict.h: Update prototype list to match predict.c. * predict.c (maybe_hot_count_p): Export. (cgraph_edge::maybe_hot_p): Move to cgraph.c. (cgraph_node::optimize_for_size_p): Move to cgraph.h. * cgraph.h (cgraph_node::optimize_for_size_p): Relocate here. * cgraph.c (cgraph_edge::maybe_hot_p): Relocate here. * profile.h: Adjust prototypes. * ifcvt.h: New. Relocate struct ce_if_block here. * ifcvt.c: Include ifcvt.h. * config/frv/frv.c: Include ifcvt.h. * config/frv/frv-protos.h: Add 'struct' to ce_if_block * parameters. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@216559 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/cfgloopmanip.h | 63 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 gcc/cfgloopmanip.h (limited to 'gcc/cfgloopmanip.h') diff --git a/gcc/cfgloopmanip.h b/gcc/cfgloopmanip.h new file mode 100644 index 00000000000..cbf8e7cdf36 --- /dev/null +++ b/gcc/cfgloopmanip.h @@ -0,0 +1,63 @@ +/* Loop manipulation header. + Copyright (C) 2014 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 3, 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.
