From 53b54be5fcbc396c95939ad6069f35700d455713 Mon Sep 17 00:00:00 2001 From: John Criswell Date: Wed, 14 Apr 2004 21:27:56 +0000 Subject: [PATCH] Remove code to adjust the iterator for llvm.readio and llvm.writeio. The iterator is pointing at the next instruction which should not disappear when doing the load/store replacement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12954 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/InstSelectSimple.cpp | 10 ---------- lib/Target/X86/X86ISelSimple.cpp | 10 ---------- 2 files changed, 20 deletions(-) diff --git a/lib/Target/X86/InstSelectSimple.cpp b/lib/Target/X86/InstSelectSimple.cpp index 18b595fad85..0715e20c325 100644 --- a/lib/Target/X86/InstSelectSimple.cpp +++ b/lib/Target/X86/InstSelectSimple.cpp @@ -1548,11 +1548,6 @@ void ISel::LowerUnknownIntrinsicFunctionCalls(Function &F) { LoadInst * LI = new LoadInst (CI->getOperand(1), "", true, CI); CI->replaceAllUsesWith (LI); BB->getInstList().erase (CI); - if (Before) { // Move iterator to instruction after call - I = Before; ++I; - } else { - I = BB->begin(); - } break; } case Intrinsic::writeio: { @@ -1563,11 +1558,6 @@ void ISel::LowerUnknownIntrinsicFunctionCalls(Function &F) { CI->getOperand(2), true, CI); CI->replaceAllUsesWith (LI); BB->getInstList().erase (CI); - if (Before) { // Move iterator to instruction after call - I = Before; ++I; - } else { - I = BB->begin(); - } break; } default: diff --git a/lib/Target/X86/X86ISelSimple.cpp b/lib/Target/X86/X86ISelSimple.cpp index 18b595fad85..0715e20c325 100644 --- a/lib/Target/X86/X86ISelSimple.cpp +++ b/lib/Target/X86/X86ISelSimple.cpp @@ -1548,11 +1548,6 @@ void ISel::LowerUnknownIntrinsicFunctionCalls(Function &F) { LoadInst * LI = new LoadInst (CI->getOperand(1), "", true, CI); CI->replaceAllUsesWith (LI); BB->getInstList().erase (CI); - if (Before) { // Move iterator to instruction after call - I = Before; ++I; - } else { - I = BB->begin(); - } break; } case Intrinsic::writeio: { @@ -1563,11 +1558,6 @@ void ISel::LowerUnknownIntrinsicFunctionCalls(Function &F) { CI->getOperand(2), true, CI); CI->replaceAllUsesWith (LI); BB->getInstList().erase (CI); - if (Before) { // Move iterator to instruction after call - I = Before; ++I; - } else { - I = BB->begin(); - } break; } default: -- 2.34.1
