From 1fc2a7f006876cac5ba4dbb34272c13592820983 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 24 Aug 2005 22:21:47 +0000 Subject: Remove some dead cases. Emit the indcall sequence as: mtctr inreg mr R12, inreg btctr If inreg and R12 aren't coallesced, this reduces the odds of having the mtctr and btctr in the same dispatch group. :) llvm-svn: 23023 --- llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) (limited to 'llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp') diff --git a/llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp b/llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp index 2f793808270..4e753d1d1b4 100644 --- a/llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp +++ b/llvm/lib/Target/PowerPC/PPC32ISelPattern.cpp @@ -980,8 +980,8 @@ unsigned ISel::SelectExpr(SDOperand N, bool Recording) { true); } else { Tmp1 = SelectExpr(N.getOperand(1)); + BuildMI(BB, PPC::MTCTR, 1).addReg(Tmp1); BuildMI(BB, PPC::OR, 2, PPC::R12).addReg(Tmp1).addReg(Tmp1); - BuildMI(BB, PPC::MTCTR, 1).addReg(PPC::R12); CallMI = BuildMI(PPC::CALLindirect, 3).addImm(20).addImm(0) .addReg(PPC::R12); } @@ -995,9 +995,6 @@ unsigned ISel::SelectExpr(SDOperand N, bool Recording) { for(int i = 0, e = ArgVR.size(); i < e; ++i) { switch(N.getOperand(i+2).getValueType()) { default: Node->dump(); assert(0 && "Unknown value type for call"); - case MVT::i1: - case MVT::i8: - case MVT::i16: case MVT::i32: assert(GPR_idx < 8 && "Too many int args"); if (N.getOperand(i+2).getOpcode() != ISD::UNDEF) { @@ -1022,9 +1019,6 @@ unsigned ISel::SelectExpr(SDOperand N, bool Recording) { switch (Node->getValueType(0)) { default: assert(0 && "Unknown value type for call result!"); case MVT::Other: return 1; - case MVT::i1: - case MVT::i8: - case MVT::i16: case MVT::i32: if (Node->getValueType(1) == MVT::i32) { BuildMI(BB, PPC::OR, 2, Result+1).addReg(PPC::R3).addReg(PPC::R3); -- cgit v1.2.3
