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/MachineCSE.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/MachineCSE.cpp') diff --git a/lib/CodeGen/MachineCSE.cpp b/lib/CodeGen/MachineCSE.cpp index bb1db86..3e54784 100644 --- a/lib/CodeGen/MachineCSE.cpp +++ b/lib/CodeGen/MachineCSE.cpp @@ -262,7 +262,7 @@ bool MachineCSE::isCSECandidate(MachineInstr *MI) { // Ignore stuff that we obviously can't move. const TargetInstrDesc &TID = MI->getDesc(); if (TID.mayStore() || TID.isCall() || TID.isTerminator() || - TID.hasUnmodeledSideEffects()) + MI->hasUnmodeledSideEffects()) return false; if (TID.mayLoad()) { -- cgit v1.1
