From 142ea99832ea3e5d7c798b7c2736e2f1ff82f9af Mon Sep 17 00:00:00 2001 From: Anna Thomas Date: Fri, 22 Jul 2016 17:50:08 +0000 Subject: Clang changes for overloading invariant.start and end intrinsics This change depends on the corresponding LLVM change at: https://reviews.llvm.org/D22519 The llvm.invariant.start and llvm.invariant.end intrinsics currently support specifying invariant memory objects only in the default address space. With this LLVM change, these intrinsics are overloaded for any adddress space for memory objects and we can use these llvm invariant intrinsics in non-default address spaces. Example: llvm.invariant.start.p1i8(i64 4, i8 addrspace(1)* %ptr) This overloaded intrinsic is needed for representing final or invariant memory in managed languages. llvm-svn: 276448 --- clang/test/CodeGenCXX/init-invariant.cpp | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'clang/test/CodeGenCXX/init-invariant.cpp') diff --git a/clang/test/CodeGenCXX/init-invariant.cpp b/clang/test/CodeGenCXX/init-invariant.cpp index 71eb7dd7349..815287c8e11 100644 --- a/clang/test/CodeGenCXX/init-invariant.cpp +++ b/clang/test/CodeGenCXX/init-invariant.cpp @@ -1,12 +1,12 @@ // RUN: %clang_cc1 -triple i686-linux-gnu -emit-llvm %s -o - | FileCheck %s --check-prefix=CHECK-O0 // RUN: %clang_cc1 -triple i686-linux-gnu -emit-llvm %s -O1 -o - | FileCheck %s -// Check that we add an llvm.invariant.start to mark when a global becomes +// Check that we add an llvm.invariant.start.p0i8 to mark when a global becomes // read-only.
