From 2f7cc01895ee178215b72d4548bd93a8064351e6 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Thu, 12 Jun 2014 01:46:54 +0000 Subject: Fix verifier for GlobalAliases to avoid recursing into global initializers. The verifier follows GlobalAlias operands so that it can detect cycles of alias definitions. It was doing this in a way that caused it to also recurse through initializers for the GlobalValue aliasees, and it would fail when an initializer refers to a global that is a declaration and not a definition. This patch causes it to stop recursing when it hits a global definition. llvm-svn: 210734 --- llvm/test/Verifier/alias.ll | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'llvm/test') diff --git a/llvm/test/Verifier/alias.ll b/llvm/test/Verifier/alias.ll index ff02a37bab9..d71a7cb2b6e 100644 --- a/llvm/test/Verifier/alias.ll +++ b/llvm/test/Verifier/alias.ll @@ -11,6 +11,10 @@ declare void @f() ; CHECK: Alias must point to a definition ; CHECK-NEXT: @ga +; References to a global declaration from an initializer are OK. +@gptr = global i32* @g +@gptr_a = alias i32** @gptr +; CHECK-NOT: Alias must point to a definition @test2_a = alias i32* @test2_b @test2_b = alias i32* @test2_a -- cgit v1.2.3
