From 62378bb5ab6f5c1e965e4a863f3d541772efe3c4 Mon Sep 17 00:00:00 2001 From: Matthias Braun Date: Tue, 5 Dec 2017 00:56:14 +0000 Subject: TwoAddressInstructionPass: Trigger -O0 behavior on optnone While we cannot skip the whole TwoAddressInstructionPass even for -O0 there are some parts of the pass that are currently skipped at -O0 but not for optnone. Changing this as there is no reason to have those two hit different code paths here. llvm-svn: 319721 --- llvm/lib/CodeGen/TwoAddressInstructionPass.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'llvm/lib/CodeGen/TwoAddressInstructionPass.cpp') diff --git a/llvm/lib/CodeGen/TwoAddressInstructionPass.cpp b/llvm/lib/CodeGen/TwoAddressInstructionPass.cpp index 28a4375cb28..c51340766b7 100644 --- a/llvm/lib/CodeGen/TwoAddressInstructionPass.cpp +++ b/llvm/lib/CodeGen/TwoAddressInstructionPass.cpp @@ -1661,6 +1661,10 @@ bool TwoAddressInstructionPass::runOnMachineFunction(MachineFunction &Func) { else AA = nullptr; OptLevel = TM.getOptLevel(); + // Disable optimizations if requested.
