From b45b4814f6ea5b5a3a120f45793cc44c12bac974 Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Mon, 14 Apr 2014 22:21:22 +0000 Subject: [PATCH] Use FrameSetup on frame instructions for the Mips port. I can't seem to get a testcase to show a difference here, but it's part of the unconditional-br.ll line table weirdness. llvm-svn: 206218 --- llvm/lib/Target/Mips/Mips16FrameLowering.cpp | 2 +- llvm/lib/Target/Mips/MipsSEFrameLowering.cpp | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/llvm/lib/Target/Mips/Mips16FrameLowering.cpp b/llvm/lib/Target/Mips/Mips16FrameLowering.cpp index 028b049f9a31..c01d03a1ddf6 100644 --- a/llvm/lib/Target/Mips/Mips16FrameLowering.cpp +++ b/llvm/lib/Target/Mips/Mips16FrameLowering.cpp @@ -71,7 +71,7 @@ void Mips16FrameLowering::emitPrologue(MachineFunction &MF) const { } if (hasFP(MF)) BuildMI(MBB, MBBI, dl, TII.get(Mips::MoveR3216), Mips::S0) - .addReg(Mips::SP); + .addReg(Mips::SP).setMIFlag(MachineInstr::FrameSetup); } diff --git a/llvm/lib/Target/Mips/MipsSEFrameLowering.cpp b/llvm/lib/Target/Mips/MipsSEFrameLowering.cpp index 0343a4764f79..6ad5821571d7 100644 --- a/llvm/lib/Target/Mips/MipsSEFrameLowering.cpp +++ b/llvm/lib/Target/Mips/MipsSEFrameLowering.cpp @@ -375,7 +375,8 @@ void MipsSEFrameLowering::emitPrologue(MachineFunction &MF) const { // if framepointer enabled, set it to point to the stack pointer. if (hasFP(MF)) { // Insert instruction "move $fp, $sp" at this location. - BuildMI(MBB, MBBI, dl, TII.get(ADDu), FP).addReg(SP).addReg(ZERO); + BuildMI(MBB, MBBI, dl, TII.get(ADDu), FP).addReg(SP).addReg(ZERO) + .setMIFlag(MachineInstr::FrameSetup); // emit ".cfi_def_cfa_register $fp" unsigned CFIIndex = MMI.addFrameInst(MCCFIInstruction::createDefCfaRegister(
