From 6c38f0bb071b864a6f2ae7b0cacad1b15f6e3d03 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Mon, 27 Nov 2006 01:05:10 +0000 Subject: For PR950: The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931 --- llvm/lib/Analysis/ValueNumbering.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'llvm/lib/Analysis/ValueNumbering.cpp') diff --git a/llvm/lib/Analysis/ValueNumbering.cpp b/llvm/lib/Analysis/ValueNumbering.cpp index 03b9f6b3eae..73d7ed3e4a6 100644 --- a/llvm/lib/Analysis/ValueNumbering.cpp +++ b/llvm/lib/Analysis/ValueNumbering.cpp @@ -113,8 +113,10 @@ void BVNImpl::visitCastInst(CastInst &CI) { for (Value::use_iterator UI = Op->use_begin(), UE = Op->use_end(); UI != UE; ++UI) if (CastInst *Other = dyn_cast(*UI)) - // Check that the types are the same, since this code handles casts... - if (Other->getType() == I.getType() && + // Check that the opcode is the same + if (Other->getOpcode() == Instruction::CastOps(I.getOpcode()) && + // Check that the destination types are the same + Other->getType() == I.getType() && // Is it embedded in the same function?
