From 61a1d6cb81a14eb977d7278fbde7d563be280533 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Thu, 26 Jan 2012 21:37:55 +0000 Subject: progress making the world safe to ConstantDataVector. While we're at it, allow PatternMatch's "neg" pattern to match integer vector negations, and enhance ComputeNumSigned bits to handle shl of vectors. llvm-svn: 149082 --- llvm/lib/CodeGen/MachineFunction.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'llvm/lib/CodeGen/MachineFunction.cpp') diff --git a/llvm/lib/CodeGen/MachineFunction.cpp b/llvm/lib/CodeGen/MachineFunction.cpp index 6bfd970..a720467 100644 --- a/llvm/lib/CodeGen/MachineFunction.cpp +++ b/llvm/lib/CodeGen/MachineFunction.cpp @@ -655,9 +655,12 @@ static bool CanShareConstantPoolEntry(const Constant *A, const Constant *B, if (A->getType() == B->getType()) return false; // For now, only support constants with the same size. - if (TD->getTypeStoreSize(A->getType()) != TD->getTypeStoreSize(B->getType())) + uint64_t StoreSize = TD->getTypeStoreSize(A->getType()); + if (StoreSize != TD->getTypeStoreSize(B->getType()) || + StoreSize > 128) return false; + // If a floating-point value and an integer value have the same encoding, // they can share a constant-pool entry. if (const ConstantFP *AFP = dyn_cast(A)) -- cgit v1.1
