From 61c70e98ac3c7504d31dd9bc81c4e9cb998e9984 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sat, 28 Aug 2010 04:09:24 +0000 Subject: remove unions from LLVM IR. They are severely buggy and not being actively maintained, improved, or extended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112356 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/AsmPrinter.cpp | 18 ------------------ 1 file changed, 18 deletions(-) (limited to 'lib/CodeGen/AsmPrinter/AsmPrinter.cpp') diff --git a/lib/CodeGen/AsmPrinter/AsmPrinter.cpp b/lib/CodeGen/AsmPrinter/AsmPrinter.cpp index fa0b97f..2571341 100644 --- a/lib/CodeGen/AsmPrinter/AsmPrinter.cpp +++ b/lib/CodeGen/AsmPrinter/AsmPrinter.cpp @@ -1433,21 +1433,6 @@ static void EmitGlobalConstantStruct(const ConstantStruct *CS, "Layout of constant struct may be incorrect!"); } -static void EmitGlobalConstantUnion(const ConstantUnion *CU, - unsigned AddrSpace, AsmPrinter &AP) { - const TargetData *TD = AP.TM.getTargetData(); - unsigned Size = TD->getTypeAllocSize(CU->getType()); - - const Constant *Contents = CU->getOperand(0); - unsigned FilledSize = TD->getTypeAllocSize(Contents->getType()); - - // Print the actually filled part - EmitGlobalConstantImpl(Contents, AddrSpace, AP); - - // And pad with enough zeroes - AP.OutStreamer.EmitZeros(Size-FilledSize, AddrSpace); -} - static void EmitGlobalConstantFP(const ConstantFP *CFP, unsigned AddrSpace, AsmPrinter &AP) { // FP Constants are printed as integer constants to avoid losing @@ -1573,9 +1558,6 @@ static void EmitGlobalConstantImpl(const Constant *CV, unsigned AddrSpace, return; } - if (const ConstantUnion *CVU = dyn_cast(CV)) - return EmitGlobalConstantUnion(CVU, AddrSpace, AP); - if (const ConstantVector *V = dyn_cast(CV)) return EmitGlobalConstantVector(V, AddrSpace, AP); -- cgit v1.1
