From 790366be6dbffc02533e84477757eda096a8f82d Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Sat, 13 Jan 2007 00:10:02 +0000 Subject: [PATCH] Make sure that GEP indices are only 32 or 64 bits. We're not ready for indices with other bit sizes yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33167 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Bytecode/Writer/Writer.cpp | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-) diff --git a/lib/Bytecode/Writer/Writer.cpp b/lib/Bytecode/Writer/Writer.cpp index b7987b2e944..dab25cad991 100644 --- a/lib/Bytecode/Writer/Writer.cpp +++ b/lib/Bytecode/Writer/Writer.cpp @@ -486,9 +486,11 @@ void BytecodeWriter::outputInstructionFormat0(const Instruction *I, // These should be either 32-bits or 64-bits, however, with bit // accurate types we just distinguish between less than or equal to // 32-bits or greater than 32-bits. - const IntegerType *IdxTy = - cast(I->getOperand(Idx)->getType()); - unsigned IdxId = IdxTy->getBitWidth() <= 32 ? 0 : 1; + unsigned BitWidth = + cast(I->getOperand(Idx)->getType())->getBitWidth(); + assert(BitWidth == 32 || BitWidth == 64 && + "Invalid bitwidth for GEP index"); + unsigned IdxId = BitWidth == 32 ? 0 : 1; Slot = (Slot << 1) | IdxId; } output_vbr(unsigned(Slot)); @@ -737,9 +739,11 @@ void BytecodeWriter::outputInstruction(const Instruction &I) { // These should be either 32-bits or 64-bits, however, with bit // accurate types we just distinguish between less than or equal to // 32-bits or greater than 32-bits. - const IntegerType *IdxTy = - cast(GEP->getOperand(Idx)->getType()); - unsigned IdxId = IdxTy->getBitWidth() <= 32 ? 0 : 1; + unsigned BitWidth = + cast(GEP->getOperand(Idx)->getType())->getBitWidth(); + assert(BitWidth == 32 || BitWidth == 64 && + "Invalid bitwidth for GEP index"); + unsigned IdxId = BitWidth == 32 ? 0 : 1; Slots[Idx] = (Slots[Idx] << 1) | IdxId; if (Slots[Idx] > MaxOpSlot) MaxOpSlot = Slots[Idx]; }
