From cb4596364369ea36ff5675eb12fc62d0c6f1f0dd Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 21 Jul 2009 23:34:23 +0000 Subject: add an API so target-independent codegen can determine if a constant pool entry will require relocations against it. I implemented this conservatively for ARM, someone who is knowledgable about it should see if this can be improved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76678 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineFunction.cpp | 21 ++++++++++++++++++++- 1 file changed, 20 insertions(+), 1 deletion(-) (limited to 'lib/CodeGen/MachineFunction.cpp') diff --git a/lib/CodeGen/MachineFunction.cpp b/lib/CodeGen/MachineFunction.cpp index 599efb8bd2..e6ae7dc224 100644 --- a/lib/CodeGen/MachineFunction.cpp +++ b/lib/CodeGen/MachineFunction.cpp @@ -539,10 +539,29 @@ void MachineJumpTableInfo::dump() const { print(*cerr.stream()); } const Type *MachineConstantPoolEntry::getType() const { if (isMachineConstantPoolEntry()) - return Val.MachineCPVal->getType(); + return Val.MachineCPVal->getType(); return Val.ConstVal->getType(); } + +unsigned MachineConstantPoolEntry::getRelocatationInfo() const { + if (isMachineConstantPoolEntry()) + return Val.MachineCPVal->getRelocatationInfo(); + + // FIXME: This API sucks. + + // If no relocations, return 0. + if (!Val.ConstVal->ContainsRelocations()) + return 0; + + // If it contains no global relocations, return 1. + if (!Val.ConstVal->ContainsRelocations(Reloc::Global)) + return 1; + + // Otherwise, it has general relocations. + return 2; +} + MachineConstantPool::~MachineConstantPool() { for (unsigned i = 0, e = Constants.size(); i != e; ++i) if (Constants[i].isMachineConstantPoolEntry()) -- cgit v1.2.3-18-g5258
