From 1b2f643753a2974540934ac0f1e3ffd182b0571c Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 31 Jan 2012 06:05:00 +0000 Subject: with recent changes, ConstantArray is never a "string". Remove the associated methods and constant fold the clients to false. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149362 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Bitcode/Writer/BitcodeWriter.cpp | 26 -------------------------- 1 file changed, 26 deletions(-) (limited to 'lib/Bitcode/Writer/BitcodeWriter.cpp') diff --git a/lib/Bitcode/Writer/BitcodeWriter.cpp b/lib/Bitcode/Writer/BitcodeWriter.cpp index d58f7cf73d..50c990a670 100644 --- a/lib/Bitcode/Writer/BitcodeWriter.cpp +++ b/lib/Bitcode/Writer/BitcodeWriter.cpp @@ -845,32 +845,6 @@ static void WriteConstants(unsigned FirstVal, unsigned LastVal, } else { assert (0 && "Unknown FP type!"); } - } else if (isa(C) && cast(C)->isString()) { - const ConstantArray *CA = cast(C); - // Emit constant strings specially. - unsigned NumOps = CA->getNumOperands(); - // If this is a null-terminated string, use the denser CSTRING encoding. - if (CA->getOperand(NumOps-1)->isNullValue()) { - Code = bitc::CST_CODE_CSTRING; - --NumOps; // Don't encode the null, which isn't allowed by char6. - } else { - Code = bitc::CST_CODE_STRING; - AbbrevToUse = String8Abbrev; - } - bool isCStr7 = Code == bitc::CST_CODE_CSTRING; - bool isCStrChar6 = Code == bitc::CST_CODE_CSTRING; - for (unsigned i = 0; i != NumOps; ++i) { - unsigned char V = cast(CA->getOperand(i))->getZExtValue(); - Record.push_back(V); - isCStr7 &= (V & 128) == 0; - if (isCStrChar6) - isCStrChar6 = BitCodeAbbrevOp::isChar6(V); - } - - if (isCStrChar6) - AbbrevToUse = CString6Abbrev; - else if (isCStr7) - AbbrevToUse = CString7Abbrev; } else if (isa(C) && cast(C)->isString()) { const ConstantDataSequential *Str = cast(C); -- cgit v1.2.3-18-g5258
