From d6e44ab5ec8bc0bb939a9a595d0c653602cf4a3d Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Fri, 1 Feb 2008 09:10:45 +0000 Subject: Remove the nasty LABEL hack with a much less evil one. Now llvm.dbg.func.start implies a stoppoint is set. SelectionDAGISel records a new source line but does not create a ISD::LABEL node for this special stoppoint. Asm printer will magically print this label. This ensures nothing is emitted before. llvm-svn: 46635 --- llvm/lib/CodeGen/PrologEpilogInserter.cpp | 7 ------- 1 file changed, 7 deletions(-) (limited to 'llvm/lib/CodeGen/PrologEpilogInserter.cpp') diff --git a/llvm/lib/CodeGen/PrologEpilogInserter.cpp b/llvm/lib/CodeGen/PrologEpilogInserter.cpp index 34cbb2b0778..41efbef54e2 100644 --- a/llvm/lib/CodeGen/PrologEpilogInserter.cpp +++ b/llvm/lib/CodeGen/PrologEpilogInserter.cpp @@ -249,13 +249,6 @@ void PEI::saveCalleeSavedRegisters(MachineFunction &Fn) { MachineBasicBlock *MBB = Fn.begin(); MachineBasicBlock::iterator I = MBB->begin(); - // Do not insert prologue code before debug LABELs at the start of the - // entry block. - MachineModuleInfo *MMI = FFI->getMachineModuleInfo(); - if (MMI && MMI->hasDebugInfo()) - while (I != MBB->end() && I->isDebugLabel()) - ++I; - if (!TII.spillCalleeSavedRegisters(*MBB, I, CSI)) { for (unsigned i = 0, e = CSI.size(); i != e; ++i) { // Add the callee-saved register as live-in.
