From afb6a4fe7f248d8903e07062811d58f7a96ba6b1 Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Mon, 26 Jan 2015 19:19:04 +0000 Subject: Add a FIXME about preferred alignment to DataLayout. Essentially DataLayout is global and affects the layout of ABI level objects. Preferred alignment could change on a per function basis as we change CPU features. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227118 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/IR/DataLayout.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include') diff --git a/include/llvm/IR/DataLayout.h b/include/llvm/IR/DataLayout.h index a9e75955ce7..9479ba487c2 100644 --- a/include/llvm/IR/DataLayout.h +++ b/include/llvm/IR/DataLayout.h @@ -53,6 +53,11 @@ enum AlignTypeEnum { AGGREGATE_ALIGN = 'a' }; +// FIXME: Currently the DataLayout string carries a "preferred alignment" +// for types.
