From 4798bbeaf5a76a83f2aa923b0abc792e01ac3be7 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Thu, 5 Feb 2009 06:55:21 +0000 Subject: if we have a large GEP offset on a 32-bit or other target, make sure to print the value properly sext'd to the right pointer size. This fixes PR3481. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63843 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/AsmPrinter.cpp | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'lib/CodeGen/AsmPrinter/AsmPrinter.cpp') diff --git a/lib/CodeGen/AsmPrinter/AsmPrinter.cpp b/lib/CodeGen/AsmPrinter/AsmPrinter.cpp index c6b0313c39..678488e1b4 100644 --- a/lib/CodeGen/AsmPrinter/AsmPrinter.cpp +++ b/lib/CodeGen/AsmPrinter/AsmPrinter.cpp @@ -815,6 +815,12 @@ void AsmPrinter::EmitConstantValueOnly(const Constant *CV) { SmallVector idxVec(CE->op_begin()+1, CE->op_end()); if (int64_t Offset = TD->getIndexedOffset(ptrVal->getType(), &idxVec[0], idxVec.size())) { + // Truncate/sext the offset to the pointer size. + if (TD->getPointerSizeInBits() != 64) { + int SExtAmount = 64-TD->getPointerSizeInBits(); + Offset = (Offset << SExtAmount) >> SExtAmount; + } + if (Offset) O << '('; EmitConstantValueOnly(ptrVal); -- cgit v1.2.3-70-g09d2
