From 1cce5bf8ef9ee3dc157ae5d8778f84a7a0d1d8b9 Mon Sep 17 00:00:00 2001 From: Stepan Dyatkovskiy Date: Sat, 12 May 2012 10:48:17 +0000 Subject: Recommited r156374 with critical fixes in BitcodeReader/Writer: Ordinary patch for PR1255. Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object. Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156704 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/VMCore/Instructions.cpp | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'lib/VMCore') diff --git a/lib/VMCore/Instructions.cpp b/lib/VMCore/Instructions.cpp index 6c5db32876..819a090cc3 100644 --- a/lib/VMCore/Instructions.cpp +++ b/lib/VMCore/Instructions.cpp @@ -3169,6 +3169,13 @@ SwitchInst::~SwitchInst() { /// addCase - Add an entry to the switch instruction... /// void SwitchInst::addCase(ConstantInt *OnVal, BasicBlock *Dest) { + CRSBuilder CB; + CB.add(OnVal); + ConstantRangesSet CRS = CB.getCase(); + addCase(CRS, Dest); +} + +void SwitchInst::addCase(ConstantRangesSet& OnVal, BasicBlock *Dest) { unsigned NewCaseIdx = getNumCases(); unsigned OpNo = NumOperands; if (OpNo+2 > ReservedSpace) @@ -3177,7 +3184,7 @@ void SwitchInst::addCase(ConstantInt *OnVal, BasicBlock *Dest) { assert(OpNo+1 < ReservedSpace && "Growing didn't work!"); NumOperands = OpNo+2; CaseIt Case(this, NewCaseIdx); - Case.setValue(OnVal); + Case.setValueEx(OnVal); Case.setSuccessor(Dest); } -- cgit v1.2.3-18-g5258
