From c36b7069b42bece963b7e6adf020353ce990ef76 Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Fri, 7 Jan 2011 23:50:32 +0000 Subject: Do not model all INLINEASM instructions as having unmodelled side effects. Instead encode llvm IR level property "HasSideEffects" in an operand (shared with IsAlignStack). Added MachineInstrs::hasUnmodeledSideEffects() to check the operand when the instruction is an INLINEASM. This allows memory instructions to be moved around INLINEASM instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123044 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/PeepholeOptimizer.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/PeepholeOptimizer.cpp') diff --git a/lib/CodeGen/PeepholeOptimizer.cpp b/lib/CodeGen/PeepholeOptimizer.cpp index 1ddfe8b7c2..54466efd5a 100644 --- a/lib/CodeGen/PeepholeOptimizer.cpp +++ b/lib/CodeGen/PeepholeOptimizer.cpp @@ -338,7 +338,7 @@ bool PeepholeOptimizer::runOnMachineFunction(MachineFunction &MF) { if (MI->isLabel() || MI->isPHI() || MI->isImplicitDef() || MI->isKill() || MI->isInlineAsm() || MI->isDebugValue() || - MI->getDesc().hasUnmodeledSideEffects()) + MI->hasUnmodeledSideEffects()) continue; if (MI->getDesc().isCompare()) { -- cgit v1.2.3-70-g09d2
