From 0c7b63356c52e94b98d574343c581ca196cb1a2d Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Fri, 6 Mar 2009 10:21:56 +0000 Subject: While thinking about the one-definition-rule and trying to find a tiny mouse hole to squeeze through, it struck me that globals without a name can be considered internal since they can't be referenced from outside the current module. This patch makes GlobalOpt give them internal linkage. Also done for aliases even though they always have names, since in my opinion anonymous aliases should be allowed for consistency with global variables and functions. So if that happens one day, this code is ready! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66267 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/GlobalOpt/2009-03-06-Anonymous.ll | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 test/Transforms/GlobalOpt/2009-03-06-Anonymous.ll (limited to 'test/Transforms/GlobalOpt') diff --git a/test/Transforms/GlobalOpt/2009-03-06-Anonymous.ll b/test/Transforms/GlobalOpt/2009-03-06-Anonymous.ll new file mode 100644 index 0000000..ea13d29 --- /dev/null +++ b/test/Transforms/GlobalOpt/2009-03-06-Anonymous.ll @@ -0,0 +1,11 @@ +; RUN: llvm-as < %s | opt -globalopt | llvm-dis | grep internal | count 2 + +global i32 0 +define i32* @1() { + ret i32* @0 +} +define i32* @f() { +entry: + call i32* @1() + ret i32* %0 +} -- cgit v1.1
