From 2053c8ce3108f50feb5e4c7216fae42fb4c93fbd Mon Sep 17 00:00:00 2001 From: hubicka Date: Fri, 11 Jun 2010 14:33:28 +0000 Subject: [PATCH] * df-problems.c (df_live_scratch): Convert to bitmap_head. (df_live_alloc): Initialize df_live_scratch when initializing problem_data. (df_live_transfer_function): Update uses of df_live_scratch. (df_live_free): Free problem_data; clear df_live_scratch before releasing the obstack. (df_md_free): Free problem data. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@160612 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/ChangeLog | 10 ++++++++++ gcc/df-problems.c | 17 +++++++++-------- 2 files changed, 19 insertions(+), 8 deletions(-) diff --git a/gcc/ChangeLog b/gcc/ChangeLog index 59f69396a6e..d564d3639f4 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,5 +1,15 @@ 2010-06-11 Jan Hubicka + * df-problems.c (df_live_scratch): Convert to bitmap_head. + (df_live_alloc): Initialize df_live_scratch when initializing + problem_data. + (df_live_transfer_function): Update uses of df_live_scratch. + (df_live_free): Free problem_data; clear df_live_scratch before + releasing the obstack. + (df_md_free): Free problem data. + +2010-06-11 Jan Hubicka + * doc/invoke.texi (Wsuggest-attribute): Document.
