From f6eb7e3175aa0bb69152196bff69beade5fb8f38 Mon Sep 17 00:00:00 2001 From: Jingyue Wu Date: Sun, 15 Jun 2014 21:40:57 +0000 Subject: Canonicalize addrspacecast ConstExpr between different pointer types As a follow-up to r210375 which canonicalizes addrspacecast instructions, this patch canonicalizes addrspacecast constant expressions. Given clang uses ConstantExpr::getAddrSpaceCast to emit addrspacecast cosntant expressions, this patch is also a step towards having the frontend emit canonicalized addrspacecasts. Piggyback a minor refactor in InstCombineCasts.cpp Update three affected tests in addrspacecast-alias.ll, access-non-generic.ll and constant-fold-gep.ll and added one new test in constant-fold-address-space-pointer.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211004 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Other/constant-fold-gep.ll | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test/Other/constant-fold-gep.ll') diff --git a/test/Other/constant-fold-gep.ll b/test/Other/constant-fold-gep.ll index aed4145c55..dc122fd161 100644 --- a/test/Other/constant-fold-gep.ll +++ b/test/Other/constant-fold-gep.ll @@ -457,7 +457,7 @@ define i8* @different_addrspace() nounwind noinline { %p = getelementptr inbounds i8* addrspacecast ([4 x i8] addrspace(12)* @p12 to i8*), i32 2 ret i8* %p -; OPT: ret i8* getelementptr (i8* addrspacecast ([4 x i8] addrspace(12)* @p12 to i8*), i32 2) +; OPT: ret i8* getelementptr (i8* addrspacecast (i8 addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @p12, i32 0, i32 0) to i8*), i32 2) } define i8* @same_addrspace() nounwind noinline { -- cgit v1.2.3
