From d0f03375468f173a33fe2f655e260c0ff6209e25 Mon Sep 17 00:00:00 2001 From: rsandifo Date: Mon, 12 Jul 2010 18:55:48 +0000 Subject: gcc/ * Makefile.in (LIBFUNCS_H): Add $(HASHTAB_H). (target-globals.o): Depend on $(LIBFUNCS_H). * libfuncs.h: Include hashtab.h. (libfunc_entry): Moved from optabs.c. (target_libfuncs): New structure. (default_target_libfuncs): Declare. (this_target_libfuncs): Declare as a variable or define as a macro. (libfunc_table): Redefine as a macro. * optabs.c (default_target_libfuncs): New variable. (this_target_libfuncs): New conditional variable. (libfunc_table): Delete. (libfunc_entry): Moved to optabs.h. (libfunc_hash): Redefine as a macro. (hash_libfunc, eq_libfunc): Fix comments. (init_optabs): Use libfunc_hash to detect cases where the function has already been called. Clear the hash table instead of recreating it. * target-globals.h (this_target_libfuncs): Declare. (target_globals): Add a libfuncs field. (restore_target_globals): Copy the libfuncs field to this_target_libfuncs. * target-globals.c: Include libfuncs.h. (default_target_globals): Initialize the libfuncs field. (save_target_globals): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@162099 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/optabs.c | 40 +++++++++++++++------------------------- 1 file changed, 15 insertions(+), 25 deletions(-) (limited to 'gcc/optabs.c') diff --git a/gcc/optabs.c b/gcc/optabs.c index e9487d0367e..b9db02fe83f 100644 --- a/gcc/optabs.c +++ b/gcc/optabs.c @@ -46,11 +46,14 @@ along with GCC; see the file COPYING3.
