From 58376d8ede436eb1fe474bca1582a4f7afe613f9 Mon Sep 17 00:00:00 2001 From: Matt Arsenault Date: Fri, 26 Jul 2013 17:37:20 +0000 Subject: Re-add DataLayout pointer size convenience functions. These were reverted in r167222 along with the rest of the last different address space pointer size attempt. These will be used in later commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187223 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/IR/DataLayout.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'include') diff --git a/include/llvm/IR/DataLayout.h b/include/llvm/IR/DataLayout.h index c15591b6d2..269edeb9f3 100644 --- a/include/llvm/IR/DataLayout.h +++ b/include/llvm/IR/DataLayout.h @@ -271,6 +271,18 @@ public: unsigned getPointerSizeInBits(unsigned AS = 0) const { return getPointerSize(AS) * 8; } + + /// Layout pointer size, in bits, based on the type.
