From 0334b31204f696717d29149d8f32c488ad6cfd6c Mon Sep 17 00:00:00 2001 From: vries Date: Fri, 30 Oct 2015 08:38:24 +0000 Subject: [PATCH] Cleanup fipa-pta constraint dumping 2015-10-30 Tom de Vries * tree-ssa-structalias.c (ipa_pta_execute): Declare variable from as unsigned, and initialize, and use initial value instead of hardcoded constant. Add generic constraints dumping section. Don't dump global initializers constraints dumping section if empty. Don't update variable from if unused. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@229569 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/ChangeLog | 8 ++++++++ gcc/tree-ssa-structalias.c | 19 ++++++++++++++----- 2 files changed, 22 insertions(+), 5 deletions(-) diff --git a/gcc/ChangeLog b/gcc/ChangeLog index 934711b183b1..e9379ddc4901 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,3 +1,11 @@ +2015-10-30 Tom de Vries + + * tree-ssa-structalias.c (ipa_pta_execute): Declare variable from as + unsigned, and initialize, and use initial value instead of hardcoded + constant.
