From dd045aeeddc65c15840ac25e90f729e2805dfc17 Mon Sep 17 00:00:00 2001 From: meyering Date: Wed, 20 Apr 2011 18:19:03 +0000 Subject: remove useless if-before-free tests Change "if (E) free (E);" to "free (E);" everywhere except in the libgo/, intl/, zlib/ and classpath/ directories. Also transform equivalent variants like "if (E != NULL) free (E);" and allow an extra cast on the argument to free. Otherwise, the tested and freed "E" expressions must be identical, modulo white space. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@172785 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-data-ref.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'gcc/tree-data-ref.c') diff --git a/gcc/tree-data-ref.c b/gcc/tree-data-ref.c index e01c67722f7..04606052225 100644 --- a/gcc/tree-data-ref.c +++ b/gcc/tree-data-ref.c @@ -5127,11 +5127,9 @@ free_rdg (struct graph *rdg) struct graph_edge *e; for (e = v->succ; e; e = e->succ_next) - if (e->data) - free (e->data); + free (e->data); - if (v->data) - free (v->data); + free (v->data); } htab_delete (rdg->indices); -- cgit v1.2.1
