From e6c74c9c2a49be4500d52c2531c1a45221a530a4 Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Thu, 7 Jan 2010 19:45:14 +0000 Subject: [PATCH] If the data requires a relocation then don't attempt to add it to the constant pool for fast-isel. We already don't add it for the normal case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92934 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86FastISel.cpp | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/lib/Target/X86/X86FastISel.cpp b/lib/Target/X86/X86FastISel.cpp index 10fba2461ed..31ae50e748d 100644 --- a/lib/Target/X86/X86FastISel.cpp +++ b/lib/Target/X86/X86FastISel.cpp @@ -19,6 +19,7 @@ #include "X86RegisterInfo.h" #include "X86Subtarget.h" #include "X86TargetMachine.h" +#include "llvm/Constant.h" #include "llvm/CallingConv.h" #include "llvm/DerivedTypes.h" #include "llvm/GlobalVariable.h" @@ -1652,6 +1653,12 @@ unsigned X86FastISel::TargetMaterializeConstant(Constant *C) { PICBase = X86::RIP; } + // If we've gotten here we need to make sure we don't have a constant + // that needs a relocation, because then we shouldn't put it into the + // constant pool. + if (C->getRelocationInfo() != Constant::NoRelocation) + return 0; + // Create the load from the constant pool. unsigned MCPOffset = MCP.getConstantPoolIndex(C, Align); unsigned ResultReg = createResultReg(RC);
